RigidTungsten carbide coatingThe theoretical hardness reaches 65~70HRC, which is the theoretical hardness achieved by domestic coating technology. Coating the sealing surface with tungsten carbide also increases the difficulty of polishing. It is recommended to use diamond grinding compound for polishing. If the sealing surface is a hard seal, opening it multiple times can affect the tungsten carbide coating, so try to avoid opening the coating during polishing.

HardenedTungsten Carbide CoatingCharacteristics of the layer

Wear-resistant coating – hardness only slightly less than diamond

2. Corrosion-resistant coating – Resists corrosive environments such as saltwater

3. Erosion-resistant coating - for applications such as water turbines in underwater environments

4. Insulating Coating - Insulating coating for metalwork capable of withstanding 3,000 volts

5. Surface Reinforcement Coating – Graphite Surface Reinforcement Anti-adhesion

6. High-Temperature Corrosion Coating – Resists ablation at 1900 degrees, mimicking high-temperature adhesion and damage to workpieces
