Overview

Tungsten Carbide coatings are the industry benchmark for severe wear protection. Applied by HVOF (High Velocity Oxy-Fuel), carbide particles are propelled at supersonic speed onto the component, forming a dense, metallurgically bonded layer with hardness far beyond hardened steel or hard chrome plating. The coating resists abrasion, erosion, and galling while preserving the base material's toughness — allowing worn components to be restored and returned to service with a surface that outlasts the original.

Frequently Asked Questions

Tungsten Carbide Coating — Common Questions

Answers to common questions about our HVOF tungsten carbide wear coating services.

What is tungsten carbide coating?

Tungsten carbide coating is an extremely hard, wear-resistant thermal spray coating (WC-Co or WC-Co-Cr) applied by HVOF to protect components from abrasion, erosion, and fretting.

How is tungsten carbide coating applied?

It is applied using the HVOF process, which propels tungsten carbide powder at supersonic speed to form a dense, low-porosity layer with excellent bond strength.

How hard is a tungsten carbide coating?

HVOF tungsten carbide coatings typically reach 1000-1300 HV, far harder than hardened steel or hard chrome plating, giving outstanding wear life.

Which components benefit from tungsten carbide coating?

Screw conveyors, rewinder rolls, pump casings, shaft sleeves, valves, and other parts exposed to severe sliding or abrasive wear.

Is tungsten carbide coating better than hard chrome plating?

For most wear applications yes, it offers higher hardness, better wear resistance, and is a cleaner alternative to hexavalent-chromium hard chrome plating.
