Tungsten carbide coating applied by spray coating on conveying rollers using supersonic thermal spraying technology.

Guangzhou Sanxin Company uses supersonic thermal spraying equipment to apply tungsten carbide coatings onto the surface of conveyor rollers in electronic copper foil production lines, creating wear-resistant and corrosion-proof coatings. After precision grinding, the surface achieves a mirror-like finish that does not scratch the copper foil. A tungsten carbide coating is a type of coating applied to a substrate’s surface, with tungsten carbide as its primary component. Tungsten carbide is an extremely hard ceramic material that boasts excellent properties such as a high melting point, exceptional hardness, outstanding wear resistance, and superior corrosion resistance. By forming a tungsten carbide coating on metal surfaces, the hardness, wear resistance, corrosion resistance, and high-temperature performance of these surfaces can be significantly enhanced. Tungsten carbide coatings are typically prepared using techniques such as physical vapor deposition, chemical vapor deposition, and arc ion plating. They are widely used in fields including tools, molds, aerospace, automotive, and machinery.
