Complicated Highly Wear-Resistant Parts

The main alloying elements are chromium, molybdenum, and tungsten, with small amounts of niobium, tantalum and indium. In addition to its wear resistance, it has good oxidation resistance, corrosion resistance and welding performance. It can be used to manufacture wear-resistant parts, and can also be used as a cladding material to coat the surface of other base materials through surfacing and spraying processes. Nickel-based alloy powder includes self-fluxing alloy powder and non-self-fluxing alloy powder. The non-self-fluxing nickel-based powder refers to the 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.

Products Details

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 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. The nickel-based self-fluxing alloy powder is formed by adding appropriate amount of B and Si to the nickel 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 alloying elements (mainly boron and silicon) that can form a low-melting eutectic in nickel, cobalt, and iron-based alloys. Material.Commonly used nickel-based self-fluxing alloy powders include 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-W-C-based self-fluxing alloy powder, high copper self-fluxing alloy powder, tungsten carbide dispersion nickel-based self-fluxing powder Alloy powder, etc. The role of boron and silicon elements: significantly reduce the melting point of the alloy, expand the solid liquidus temperature zone, and form a low-melting eutectic; deoxidation reduction and slag-forming functions; hardening and strengthening of coatings.
