30Co 25Ni 16Cr 6Al 0.3Y 4BN 15Polyester Powder Description:
30Co 25Ni 16Cr 6Al 0.3Y 4BN 15Polyester Powder is a specialized composite thermal spray powder tailored for abradable coatings in high-pressure compressor sections of jet engines and industrial gas turbines. It features a CoNiCrAlY matrix for superior oxidation and corrosion resistance, coupled with boron nitride for solid lubrication, enhancing abradability and reducing wear during operational surges. The coating’s-controlled porosity, adjusted through polyester content, ensures optimal friability against various metal components, making it ideal for applications demanding reliability under extreme environmental conditions. Heat treatment post-spray enhances porosity, further optimizing performance and durability up to service temperatures of 750°C (1380°F).
