Ni 17Cr 4Fe 4Si 3.5B 1C Powder Description:
Ni 17Cr 4Fe 4Si 3.5B 1C Powder is a fully alloyed, gas-atomized powder featuring a spheroidal shape, which ensures excellent flowability during coating applications. It is tailored for a two-step 'spray and fuse' process, wherein the material is initially applied using thermal spray and subsequently fused to create a fully dense, metallurgically bonded microstructure devoid of oxides and porosity. The inclusion of boron and silicon permits fusing at lower temperatures, generating hard phases that significantly improve wear resistance. This alloy achieves a fused hardness of approximately HRC 55 to 60 and experiences a shrinkage of around 10% during the fusing process. The typical fusing temperature for this powder is about 993°C, making it ideal for applications that demand high hardness and wear resistance.
