NiCr 80/20 Thermal Spray Wire for Arc Spraying: High-Performance Coating Solution
Product Description for NiCr 80/20 Thermal Spray Wire for Arc Spraying
Product Introduction
NiCr 80/20 thermal spray wire is a high-quality material designed for arc spraying applications. This wire is composed of 80% nickel and 20% chromium, making it an excellent choice for creating coatings that require high-temperature resistance, corrosion resistance, and oxidation resistance. NiCr 80/20 is widely used in various industries, including aerospace, power generation, petrochemical, and manufacturing, to protect and restore surfaces, enhance wear resistance, and extend the lifespan of critical components. Its superior performance in harsh environments makes it a reliable solution for demanding applications.
Surface Preparation
Proper surface preparation is crucial to achieve optimal results with NiCr 80/20 thermal spray wire. The surface to be coated should be meticulously cleaned to remove contaminants such as grease, oil, dirt, and oxides. Grit blasting with aluminum oxide or silicon carbide is recommended to achieve a surface roughness of 50-75 microns. Ensuring a clean and roughened surface enhances the adhesion of the thermal spray coating, leading to improved performance and longevity.
