| abstract | 1518416 Reinforced superalloy bodies WESTINGHOUSE CANADA Ltd 8 June 1976 [9 June 1975] 23588/76 Headings C7D and C7F A composite material comprises a matrix of Ni- or Co-based superalloy, and filaments coated with hafnium carbide, hafnium nitride, titanium nitride, zirconium carbide or zirconium nitride as a barrier layer to prevent diffusion at elevated temperatures. The filaments may be of graphite, SiC, Mo, W, or W alloyed with one of K, Si, Re, ThO 2 or hafnium carbide. The barrier layer is deposited by sputtering, electron beam evaporation, ion plating or preferably by chemical vapour deposition. Examples relate to coating wires of W-2% ThO 2 with hafnium carbide, hafnium nitride, and titanium nitride. In the figure a W filament 3 passes through chamber 4 sealed by Hg seals 5, 6, the filament being heated to 900-1300‹C by current supplied to electrodes 15,16. To deposit hafnium carbide, hafnium is held in chamber 10 and converted by HCL gas or CL2 to hafnium chloride which flows out into tube 12 and reacts with a CH 4 /H 2 mixture from tube 13. To deposit titanium nitride, titanium chloride is reacted with N2. In the Examples, coated filaments are placed in a container and surrounded with superalloy powder, the container being subjected to hot isostatic pressing in argon. |
