Plasma-sprayed semicircular discs for chromium oxide thermal spraying—wear-resistant semicircular disc coating processing equipment

Guangzhou Sanxin Semi-Circular Disc Coating with Chromium Oxide Using plasma spraying technology, pure chromium oxide (Cr₂O₃) is precisely applied onto the curved surface of the semi-circular disc, forming a dense protective layer. This coating achieves a dual breakthrough in wear resistance and corrosion resistance, offering exceptional hardness and wear resistance: the microhardness of the coating ranges from HV1200 to 1463, three times that of conventional chrome plating, significantly extending the service life of fiber-drawing guide wheels. Precisely tailored to suit various applications, with customizable thickness and surface finish: the coating thickness is adjustable from 50 to 300 μm, with an error margin of ±3%.

Supersonic Spray Disc Coating Tungsten Carbide

Guangzhou Sanxin Disc Spray Tungsten Carbide Sprayed using the SX-8000 supersonic spraying system, this coating features a radial powder feed design that ensures more thorough powder melting, resulting in a coating density 30% higher than that of conventional HVOF coatings. Outstandingly hard and wear-resistant—its wear life is more than six times longer than that of ordinary stainless steel. Exceptional erosion resistance: its wear rate is 80% lower than that of traditional chrome-plated coatings. Leading performance in high-temperature and corrosion resistance: suitable for applications involving temperatures up to 1500℃ (e.g., industrial kilns and blast furnace tuyeres).

Dual-insulation and wear-resistant protection: Guangzhou Sanxin alumina spraying empowers high-precision coating.

Guangzhou Sanxin has deeply cultivated alumina spraying technology for coating machine components, with insulation as its core strength. By integrating multiple features—such as wear resistance, high-temperature resistance, and corrosion protection—it has become the preferred choice for industry procurement.
