Thermal spray alloy
Thermal spraying of alloys is a technique of preparing coatings for the protection of metal surfaces.
Thermal spraying alloy technology forms a dense coating by heating the alloy material to a molten or semi-molten state and then spraying it onto the surface of the substrate at high speed. This coating has a variety of excellent properties, such as wear-resistant, corrosion-resistant, oxidation-resistant, high-temperature oxidation-resistant, thermal shock-resistant, and abrasion-resistant. This effectively protects the substrate material and prolongs its service life. Thermal spraying alloy technology is widely used in mechanical parts of the surface wear, corrosion protection or remanufacturing repair, especially in the need to withstand high temperatures, high pressure, corrosion and other harsh environmental conditions. Show its unique advantages.
Specific applications of thermal spray alloys include, but are not limited to.
WC-based coatings: WC-Co, WC-Ni, WC-Co-Cr, etc. as the representative of the cemented carbide coatings, because of its high hardness, good toughness and excellent wear and corrosion resistance, is widely used in mechanical parts surface protection. It is widely used for surface protection of mechanical parts.
Nickel-aluminum base layer materials: Pre-alloyed nickel-aluminum base layer materials, such as Ni95Al5, are suitable for arc spraying process. This kind of coating has the performance of high temperature oxidation resistance, thermal shock resistance and abrasion resistance, and the bonding strength is above 55MPa, which can be directly used as the working layer.
The advantages of thermal spraying alloy technology lie in its outstanding comprehensive performance, high cost performance and green and non-polluting preparation process, which is widely recognized as the preferred product that can replace the electroplated hard chrome layer that has serious environmental pollution problems.
