A new protective coating for nickel alloys

摘要: Abstract Past experience has shown that aluminide coatings are highly effective in prolonging the life of high-temperature components aircraft turbines. Increased turbine inlet temperatures, however, and thinner blade walls necessitated by use internal cooling systems call for greater corrosion resistance diffusion stability. Used on nickel alloys, LDC-2 coating is a remarkable improvement over respective contemporary technology. This borne out results cyclic sulphidation with additions sulphur synthetic sea salt, oxidation, hot thermalshock testing. The produced an aluminium treatment following galvanic platinum deposition. structure described. By application passages can be protected more effectively. reason such ducts necessarily than outer surface. LDC-2, provides high degree protection even as thin coating. It was further found after surface cleansing degraded renewed.
