NK5892 Nickel Chromium Aluminum Yttrium Alloy Spherical Powder (Ni 24.5Cr 6Al 0.4Y Powder)

Ni 24.5Cr 6Al 0.4Y Powder Description:

Ni 24.5Cr 6Al 0.4Y Powder is a specific material for thermal spray coatings, recognised for its excellent resistance to oxidation and hot corrosion. This alloy provides effective protection against corrosion at temperatures up to 980°C (1800°F) when using atmospheric plasma spraying (APS) and up to 1050°C (1920°F) during HVOF or controlled atmosphere plasma spraying (LPPS, LVPS, VPS). The presence of Chromium and Aluminium facilitates the formation of a protective oxide layer, crucial for extending the lifespan of ceramic high-temperature coating systems such as thermal barrier coatings and ceramic abrasion-resistant systems. Yttrium enhances the adhesion of this oxide layer, while Aluminium oxide acts as an oxygen diffusion barrier, minimising oxidation of the bond coat. The high Chromium content of this alloy is particularly beneficial in combating hot corrosion and sulphidation, making it a preferred choice for demanding industrial applications that require reliable performance under extreme thermal conditions.
