Tungsten carbide titanium

(W, Ti)C powder is a raw material widely used in the cemented carbide industry and other advanced materials industries. It is typically produced by dissolving two or more carbides along with other compounds such as nitrides. Our company employs a unique carburization and solid-solution process to manufacture composite carbide products that feature stable composition, uniform distribution, high solid-solution capacity, low impurity content, and controllable particle size.

Thermal Spraying Nickel-Chromium—Chromium Carbide Powder

Thermal Spraying Tungsten Carbide Powder

Tungsten carbide itself is extremely hard (with a Mohs hardness of about 9 and a Vickers hardness well above 1500 HV). However, pure tungsten carbide coatings are highly brittle and very difficult to spray. Therefore, the tungsten carbide powders used in thermal spraying are not pure WC; rather, they are composite powders made by combining WC particles with a metallic “binder phase” (typically cobalt Co, but sometimes nickel Ni, chromium Cr, or cobalt-chromium alloy CoCr).

Introduction to Wear-Resistant Powder Materials for Thermal Spraying

To reduce wear caused by material erosion on equipment components, a wear-resistant coating is applied to the surface of these components, thereby protecting the substrate material of the equipment parts. Coating processes typically include plasma-sprayed oxide ceramic coatings and supersonic flame-sprayed alloy coatings.

Introduction to Corrosion-Resistant Powder Materials for Thermal Spraying

The ceramic coating materials used in plasma spraying primarily consist of oxide ceramics from the alumina-titanium/chromium oxide series. Coatings produced by this spraying process exhibit exceptionally excellent and stable wear resistance, friction reduction, and corrosion resistance. The coating microstructure is dense, and when combined with appropriate pore-sealing treatments, these coatings are widely used in components such as plungers, piston rods, and sealing sleeves in petroleum, hydraulic, and marine equipment. They effectively mitigate the corrosive effects of media on equipment parts while also meeting stringent wear resistance requirements.

Our company has introduced advanced equipment and technology from the U.S. company TAFA to produce a wide range of thermal spray materials. We specialize in manufacturing arc-spray wires for wear-resistant and corrosion-resistant coatings, and we have been providing high-quality products and technical services for many years. Below is an introduction to some of our materials:

Selection of Thermal Spray Coating Materials

When selecting a coating material, you should first consider the service conditions of the workpiece and the performance characteristics required of the coating. You should also take into account the workpiece’s material, batch size, cost-effectiveness, and the thermal spraying method to be used.

To address the wear problem in circulating fluidized bed (CFB) boilers, and based on the wear mechanisms of CFB boilers, the coating material must possess high wear resistance, good ductility, and a certain level of corrosion resistance. Our company has introduced advanced equipment and technology from TAFA, an American company.
