Ni 24.5Cr 6Al 0.4Y Powder Description:
Ni 24.5Cr 6Al 0.4Y Powder is a high-performance thermal spray coating material celebrated for its exceptional resistance to oxidation and hot corrosion. When applied using atmospheric plasma spray (APS), it provides effective corrosion protection at temperatures up to 980°C (1800°F), and up to 1050°C (1920°F) when applied using HVOF or controlled atmosphere plasma spray methods such as LPPS, LVPS, and VPS. The combination of chromium and aluminum facilitates the development of a protective oxide scale, which is crucial for prolonging the life of high-temperature ceramic coating systems, including thermal barrier coatings and ceramic abradable systems.
Yttrium enhances the adhesion of this oxide layer, while aluminum oxide serves as an oxygen diffusion barrier, reducing bond coat oxidation. The high chromium content of this alloy is particularly effective in combating hot corrosion and sulfidation, making it an ideal choice for industrial applications that demand robust performance under extreme thermal conditions.
