- Description
- This notice is a combined synopsis/solicitation for Other Than Commercial Item. This announcement constitutes the only solicitation; offers are being requested and a written solicitation will not be issued. The Government intends to acquire the other than commercial item using the Simplified Acquisition Procedures set forth in FAR Part 13. This notice is being issued as a Request for Quotations (RFQ) for Layered Barrier Coatings. Scope of Work: NASA Glenn Research Center (GRC) has requirements to produce a series of multi-layer ceramic oxide coatings with selected compositions and rare earth doping levels to achieve thermal protection, environmental protection, as well as temperature and erosion sensing functions for coated turbine engine components. NASA coating designs shall be implemented to produce protective coatings on NASA-provided substrates that shall be coated and delivered to NASA for testing of coating performance. All coatings shall be deposited on 1?? diameter coupons for performance testing, however, depositions must be performed in a system of sufficiently large dimensions where identical coatings could later be deposited onto turbine engine components such as turbine blades or vanes. All coatings shall be deposited continuously by the Contractor, with no interruption between layers, by electron-beam physical vapor deposition (EB-PVD) using industry standard deposition conditions and rates. Depositions shall be performed in an industrial scale or industrial prototype EB-PVD facility in order to achieve the deposition rates necessary for industry-standard coatings. Continuous deposition is essential in order to achieve the continuous columnar microstructure that provides the coatings with their required strain tolerance. The layered coatings and rare-earth doping shall be produced by co-evaporation of multiple ingot feedstocks along with mechanical shuttering. Coatings shall be deposited at elevated temperatures greater than 1000?aC by EB-radiant heat. Substrates provided by NASA will be one-inch diameter platimum-aluminide-coated Rene N5 superalloy substrates (PtAl/Rene N5) as well as sacrificial carbon substrates that will be used to produce freestanding coatings. Statement of Work: I. Luminescent dopant-layered TBCs The Contractor shall deposit 7wt% yttria-stabilized zirconia (7YSZ) coatings incorporating selected rare earth oxide dopant layers that will function as damage or temperature indicators. The dopant-layered 7YSZ coatings shall be deposited onto PtAl/Rene N5 substrates as well as graphite substrates provided by NASA using the Contractors industrial prototype EB-PVD facility by co-evaporation of multiple ingot feed-stocks. The layered coatings shall be deposited in a continuous fashion without interruption between layers in order to achieve continuous columnar microstructure without distinct microstructural interfaces. Coatings deposition rate shall be equal to standard industrial practice. Coatings shall be deposited at elevated temperatures >1000 0C by EB-radiant heat. Minimum of ten 1??diam PtAl/Rene N5 substrates per run (except for exploratory runs 1 and 2) along with two 1?? diameter graphite substrates. Europia (Eu2O3), terbia (Tb2O3), and dysprosia (Dy2O3) ingots with outer diameter (OD) = 1.05?? shall be provided by NASA. 7YSZ ingot with OD = 1.94?? shall be provided by NASA. A The Contractor shall conduct single dopant layer (~3 at%) trial runs as a precursor to multiple dopant layer runs. Several runs for each dopant composition shall be performed for establishing the optimum deposition parameters that can then be applied in subsequent deposition runs #4 and #5. Run #1: 6 mil Eu2O3-doped 7YSZ/PtAl/Rene N5 (to establish deposition parameters for co-evaporation of europia and 7YSZ ingots) Run #2: 6 mil Tb2O3-doped 7YSZ/PtAl/Rene N5 (to establish deposition parameters for co-evaporation of terbia and 7YSZ ingots) Run #3: 2 mil undoped 7YSZ/6 mil Eu2O3-doped 7YSZ/PtAl/Rene N5 (to gain experience with transition from doped to undoped layers) B. The Contractor shall deposit multilayer doped TBCs (~3 at% dopant). Each layer shall have thickness 2 mils Run #4: undoped 7YSZ/Eu2O3-doped 7YSZ/Tb2O3-doped 7YSZ/PtAl/Rene N5 Run #5: Same as Run #3 above but with lower Eu2O3 and Tb2O3 doping levels (<1 at%) Run #6: 7 mils undoped 7YSZ/1 mil Eu2O3-doped (3 at%) 7YSZ/PtAl/Rene N5 Run #7: 5 mils undoped 7YSZ/1 mil Eu2O3-doped (3at%) 7YSZ/PtAl/Rene N5 Run #8: 5 mils undoped 7YSZ/0.4 mil Eu2O3-doped (3at%) 7YSZ/PtAl/Rene N5 Run #9: 1 mil Eu2O3-doped (3 at%) 7YSZ/7 mils undoped 7YSZ/PtAl/Rene N5 Run #10: 1 mil Dy2O3-doped (1 at%)/6 mil undoped/1 mil Eu2O3-doped/PtAl/Rene N5 II. Environmental Barrier/Thermal Barrier Coating (EBC/TBC) interlayers The Contractor shall deposit graded layers comprised of alternating layers of TBC and EBC compositions for the purpose of reducing the stress concentration at the EBC/TBC interface. The EBC composition shall be mullite and the TBC composition shall be either HfO2-27wt%Y2O3 or ZrO2-Y2O3?VRe2O3 (Re = rare earth element). The number of layers shall range from 10 to 20 layers. Alternating composition sublayers shall have thickness ranging from 5 to 20 microns. Within these ranges, NASA shall specify the number of layers and the thickness of each individual sublayer. ZrO2-Y2O3?VRe2O3 ingot (OD = 1.94??) shall be provided by NASA. Mullite and HfO2-27wt%Y2O3 ingots shall be provided by vendor. Runs #11 and 12: The Contractor shall deposit alternating layers of mullite and HfO2-27wt%Y2O3 onto EBC/Si-coated silicon carbide fiber reinforced silicon carbide matrix composite (SiC/SiC) substrates provided by NASA. The coatings deposited in runs 11 and 12 shall contain different numbers and thicknesses (within ranges described in preceding paragraph) of mullite and HfO2-27wt%Y2O3 layers as prescribed by NASA. Run #13: The Contractor shall deposit alternating layers of mullite and ZrO2-Y2O3?VRe2O3 onto EBC/Si-coated SiC/SiC substrates provided by NASA. The number of layers and the thickness of the individual layers shall be in the ranges described above and will be prescribed by NASA. III. Highly Reflective Multi-Layer Coating Radiation barrier coatings shall be deposited that will exhibit high infrared reflectance due to the coherent interference of reflections from interfaces between layers of Al2O3 and 7YSZ. Layers shall exhibit sharp interfaces and layer thicknesses shall follow requirements given below. The contractor shall deposit alternating layers of Al2O3 and 7YSZ by co-evaporating ingots while employing a rotating shutter. 7YSZ ingot (OD = 1.94??) shall be supplied by NASA. Al2O3 ingot shall be provided by the vendor. Minimum of eight 1??diam PtAl/Rene N5 substrates along with two 1?? diameter graphite substrates. Substrates shall be supplied by NASA. The Contractor shall control layer thicknesses by increasing the shutter rotation speed with thickness adjustments of 5 nm increments. Al2O3 sublayers start at 765 nm thickness (next to substrate) and decrease to 115 nm thickness (at surface) in 5 nm increments. 7YSZ sublayers start at 740 nm (next to substrate) and decrease to 90 nm (at surface) in 5 nm increments. Run #14: The Contractor shall deposit a total of 262 sublayers alternating between Al2O3 (odd-numbered layer) and 7YSZ (even-numbered layer). The initial odd-numbered layer (Al2O3) shall have thickness of 765 nm and each subsequent odd-numbered layer shall have thickness 5 nm less than previous odd-numbered layer until the last odd-number layer (layer 261) is deposited with a thickness of 115 nm. The initial even-numbered layer (7YSZ) shall have thickness of 740 nm and each subsequent even-numbered layer shall have thickness 5 nm less than previous even-numbered layer until the last even-numbered layer (layer 262 nm) is deposited with a thickness of 90 nm. Therefore, the layer thicknesses shall be as follows: Starting closest to substrate, Layer 1 = Al2O3, thickness = 765 nm Layer 2 = 7YSZ, thickness = 740 nm Decrease each succeeding composition sublayer by 5 nm, Layer 3 = Al2O3, thickness = 760 nm Layer 4 = 7YSZ, thickness = 735 nm Continue decreasing sublayers by 5 nm increments until, Layer 261 = Al2O3, thickness = 115 nm Layer 262 = 7YSZ, thickness = 90 nm Summary of Deliverables: The Contractor shall deliver all coated specimens within 9 months of the contract award. NASA shall supply all substrates for deposition. For runs 1-10 and 14, substrates shall be a mixture of 1?? diameter PtAl-coated Rene N5 superalloy substrates and 1?? diameter graphite disks. For runs 11-13, substrates shall be EBC/Si-coated SiC substrates. The number of delivered coatings on each type of substrate for each run shall be as follows: Run #1: 4 on PtAl/Rene N5, 2 on graphite Run #2: 4 on PtAl/Rene N5, 2 on graphite Run #3: 10 on PtAl/Rene N5, 2 on graphite Run #4: 10 on PtAl/Rene N5, 2 on graphite Run #5: 10 on PtAl/Rene N5, 2 on graphite Run #6: 10 on PtAl/Rene N5, 2 on graphite Run #7: 10 on PtAl/Rene N5, 2 on graphite Run #8: 10 on PtAl/Rene N5, 2 on graphite Run #9: 10 on PtAl/Rene N5, 2 on graphite Run #10: 10 on PtAl/Rene N5, 2 on graphite Run #11: 10 on EBC/Si-coated SiC Run #12: 10 on EBC/Si-coated SiC Run #13: 10 on EBC/Si-coated SiC Run #14: 8 on PtAl/Rene N5, 4 on graphite **NOTE TO PROSPECTIVE OFFERORS: OFFEROR MUST INCLUDE ADEQUATE INFORMATION IN THEIR QUOTATION FOR THE GOVERNMENT TO EVALUATE WHETHER OR NOT THEIR OFFER MEETS THE ABOVE STATEMENT OF WORK** The provisions and clauses in the RFQ are those in effect through FAC 01-13.
