Wear-resistant Alloy

The main alloying elements are chromium, molybdenum, tungsten, but also contain small amounts of niobium, tantalum and indium. In addition to wear resistance, its oxidation resistance, corrosion resistance, welding performance is good. It can be used as a coating material, which can be coated on the surface of other base materials by surfacing welding and spraying process.
Nickel base powders include self-fluxing alloy powder and non-self-fluxing alloy powder.
The non-self-fluxing nickel-based powder refers to the nickel-based alloy powder which does not contain B, Si or B, Si content is low. This kind of powder is widely used in plasma arc spraying coating, flame spraying coating and plasma surface strengthening. It mainly includes: Ni-Cr alloy powder, Ni-Cr-Mo alloy powder, Ni-Cr-Fe alloy powder, Ni-Cu alloy powder, Ni-P and Ni-Cr-P alloy powder, Ni-Cr-Mo-Fe alloy powder, Ni-Cr-Mo-Si high wear-resistant alloy powder, Ni-Cr-Fe-Al alloy powder, Ni-Cr- Fe-Al-B-Si alloy powder, Ni-Cr-Si alloy powder, Ni-Cr-W based wear resistance alloy powder, etc.
The nickel base self-fluxing alloy powder was formed by adding proper amount of B and Si to the nickel alloy powder. The so-called self-melting alloy powder is also known as low eutectic alloy, hard surface alloy, which is a series of powder materials formed by adding low-melting eutectic alloy elements (mainly boron and silicon) to nickel, cobalt and iron-based alloys. Commonly used nickel-based self-fluxing alloy powders are Ni-B-Si alloy powder, Ni-Cr-B-Si-Mo, Ni-Cr-B-Si-Mo-Cu, high molybdenum nickel base self-fluxing alloy powder, high chromium molybdenum nickel base self-fluxing alloy powder, Ni-Cr-W-C base self-fluxing alloy powder, high copper self-fluxing alloy powder Gold powder, tungsten carbide dispersion type nickel based self-fluxing alloy powder, etc.
