The main alloying elements are chromium, molybdenum, and tungsten, but also contain a small amount of niobium, tantalum and indium. In addition to wear resistance, its oxidation resistance, corrosion resistance, and welding performance are also good. It can manufacture wear-resistant parts and can also be used as a coating material, which can be coated on the surface of other base materials through surfacing and spraying processes.

 

Nickel-based compound powder has self-fluxing alloy powder and non-self-fluxing alloy powder.

 

Non-self-fluxing nickel-based powder refers to nickel-based alloy powder that does not contain B, Si or B, and has a low Si content. This type of powder is widely used in plasma arc spray coating, flame spray coating and plasma surface strengthening. Mainly include: 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-resistant and corrosion-resistant alloy powder, etc.

 

Adding an appropriate amount of B and Si to the nickel alloy powder forms a nickel-based self-fluxing alloy powder. The so-called self-fluxing alloy powder, also known as eutectic alloy, hard-faced alloy, is a series of powders formed by adding alloy elements (mainly boron and silicon) that can form low-melting eutectic to nickel, cobalt, and iron-based alloys Material. Commonly used nickel-based self-fluxing alloy powders are Ni-B-Si alloy powder, Ni-Cr-B-Si alloy powder, Ni-Cr-B-Si-Mo, Ni-Cr-B-Si-Mo-Cu, High-molybdenum nickel-based self-fluxing alloy powder, high-chromium-molybdenum-nickel-based self-fluxing alloy powder, Ni-Cr-WC-based self-fluxing alloy powder, high-copper self-fluxing alloy powder, tungsten carbide dispersive nickel-based self-fluxing Alloy powder, etc.
