Tungsten Carbide CoatingProcessing involves applying a layer of carbide-tungsten coating to the metal surface using a spray equipment.Tungsten Carbide CoatingThe coated layer of sputtered tungsten carbide primarily serves high hardness and wear resistance.The hardness of the tungsten carbide coating after application is not related to its thickness but directly correlates with the duration of its stay within the high-temperature range.

The method for applying a wear-resistant tungsten carbide coating by spraying is to use hvof to spray cobalt-based tungsten carbide alloy powder or nickel-based tungsten carbide alloy powder.Tungsten carbide coating processing can theoretically reach 65~70HRC, which is the theoretical hardness achieved by domestic coating technology. Coating tungsten carbide on sealing surfaces also increases the technical difficulty of sanding, and it is recommended to use diamond abrasive膏 for sanding. If the sealing surface is a hard seal, the tungsten carbide coating may be affected after multiple openings.
