High hardness nickel chromium borosilicate alloy powder. It has excellent self-fluxing properties, wettability and spray weldability, and a relatively low melting point. The spray welding layer has the characteristics of high hardness, corrosion resistance, wear resistance and heat resistance. It is difficult to cut and is suitable for wet grinding.

Chromium alloy thermal spray powder There are many types of thermal spray powder, such as nickel-chromium heat-resistant alloy, which is made of chromium added to nickel of. Nickel-chromium heat-resistant alloy hardly oxidizes at high temperatures and is a typical coating material that is heat-resistant, corrosion-resistant and high-temperature oxidation resistant. The coating is dense and has good bonding performance with the base metal. It is an excellent transition layer material between the coating and the substrate of ceramics, soft metals and other materials. It can not only increase the substrate's ability to resist high-temperature gas erosion, but also improve the coating and the The bonding strength of the base material.
Ferrochrome alloy thermal spray powder. This type of thermal spray powder is made by adding appropriate iron to nickel-chromium. Its high-temperature oxidation resistance is slightly worse than that of nickel-chromium alloy. Other properties are basically the same as those of nickel-chromium alloy. Chromium series alloys are close to each other, and the most outstanding point is that they are relatively cheap, so they can be used for repairing corrosion-resistant workpieces and can also be used as transition layer thermal spray powder.
Chromium-boron alloy thermal spray powder. Since this alloy contains elements such as boron, chromium and carbon, it has relatively high hardness and moderate toughness. After spraying, its coating is wear-resistant, corrosion-resistant and resistant to It has good thermal properties and can be used for anti-corrosion repair of shafts, pistons, etc. Suitable for oxyacetylene flame or plasma spray welding process
