Laser cladding technology is an important technology for modern metal surface treatment. The cladding coating formed by laser cladding technology has low dilution rate, controllable cladding layer and convenient construction. It is widely used in the technical surface treatment of various major industries. Technology. At the same time, laser cladding technology uses a wide range of materials, mainly the following materials:
1. Self-fluxing alloy powder: mainly materials containing B, Si and other elements, which can be widely used in various types of carbon steel, alloy steel, stainless steel and cast iron.
2. Ceramic powder: Ceramic powder has excellent wear resistance, corrosion resistance, high temperature resistance and oxidation resistance characteristics, so it is often used to prepare high temperature wear and corrosion resistance coatings. At present, silicide ceramic powders and oxides are commonly used. Ceramic powder.
3. Composite powder: Composite powder mainly refers to a powder system formed by mixing or compounding high melting point hard ceramic materials with metal. The metal's toughness and good manufacturability can be organically combined with the excellent wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of ceramic materials.
4. Other metal powders: including copper-based, titanium-based, aluminum-based, magnesium-based, zirconium-based, chromium-based, and intermetallic compound matrix materials. Most of these materials use some special properties of the alloy system to achieve one or more functions such as wear resistance and friction reduction, corrosion resistance, electrical conductivity, high temperature resistance, and thermal oxidation resistance.
