Plasma Copper Plate Molybdenum Powder Spraying and Processing for SX-80—Thermal Spraying of Metal Materials

Characteristics of Plasma Spraying: (1) It can spray a wide variety of coating materials, especially those with high melting points and refractory materials such as refractory metals, ceramics, metal-ceramics, and other special functional materials. (2) Inert gases can be selected as the working medium, reducing oxidative reactions of sprayed particles during flight. (3) The coating exhibits high bonding strength and low porosity; fine coatings can be prepared by precisely controlling process parameters.

Introduction to the Plasma-Sprayed Ceramic Coating Process

A plasma flame jet is generated using a plasma torch (also known as a plasma arc generator). The tungsten electrode (cathode) and the nozzle (anode) of the torch are connected to the negative and positive terminals of the power supply, respectively (the workpiece remains electrically neutral). A high-frequency spark ignites an arc, causing the working gas supplied to the torch—either Ar or N2—to become ionized into a plasma under the influence of the arc.

Non-stick coating spray, surface coating, non-stick finish, non-stick coating material, wear-resistant and anti-adhesive spray.

The traditionally used Teflon coating exhibits excessive peel strength against hot melt adhesives, resulting in insignificant non-stick performance and inadequate wear resistance. This leads to a rapid loss of non-stick properties, lower production efficiency, shorter maintenance cycles, and increased costs.

Parts such as wire-drawing wheels, wire-drawing tower pulleys, wire-drawing cylinders, winding reels, and guide grooves used in metal wire-drawing equipment are coated with carbide ceramic coatings on their surfaces. For workpieces with particularly high wear resistance requirements, imported supersonic equipment can be used to apply tungsten carbide (hard alloy) coatings, achieving a hardness of up to HRC7.5.

We offer a range of thermal spray services, including supersonic spraying equipment from U.S. PRAXAIR and plasma equipment from U.S. Miller, all imported from Europe and the U.S. Our thermal spray coatings feature high bonding strength, exceptional density, and guaranteed superior quality.

Tungsten carbide coating for electrode roll strips

The active material, binder, and conductive agent are mixed together to form a slurry, which is then coated onto both sides of a copper or aluminum current collector. After drying, the solvent is removed to form electrode sheets. The particle coating on the electrode sheets is compacted and densified through calendering, and then the sheets are cut or slit into strips.
