Tungsten carbide coating is a very hard surface treatment that increases the resistance of metal surfaces to wear, impact and high temperatures. Tungsten carbide particles are sprayed onto the part surface using a thermal spray method, forming a hard, dense protective layer in the wear zone.
It is widely used in areas with heavy wear, such as cutting tools, mold systems, wire drawing machines, the automotive, aerospace, mining and heavy industry. On surfaces under constant friction, such as pump shafts, cylinders, rollers and valve parts, it noticeably extends part life.
The coating helps reduce the frequency of maintenance and part replacement, lowering downtime and operating costs. Worn parts can be re-coated and returned to service.
The suitable coating type depends on the part material, operating temperature, type of wear and load. Contact us with your part drawing, dimensions or a sample, and our expert team will work with you to determine the best tungsten carbide coating solution.
Frequently Asked Questions
What is tungsten carbide coating?
A hard surface coating that resists wear, impact and high temperature.
How is it applied?
With gas-fueled Sulzer Metco HVOF and liquid-fueled GTV K2 Quatro HVOF equipment. For high-temperature jobs we also apply "hot system" tungsten carbide coating.
Where is it used?
Wire drawing blocks and capstans, textile yarn machine parts, pulleys and capstans used in copper cable production, paper and textile rollers, wear-resistant seal seat coatings on bushings, worn bearing seat coatings, defense industry parts, and parts under heavy loads in machinery manufacturing. It is among the most preferred coatings against cavitation, wear and corrosion in many sectors, and it is well suited to restoring worn parts by recoating.
How hard is it?
68–72 HRc (900–1,150 HV0.3).
Can you recoat a worn part?
Yes. We can recoat a worn part, machine it back to its original dimensions and bring it back to like-new condition. If an earlier coating exists on the part, it is removed, the necessary preparation is done, and the part can be coated again with better properties.
What should I send to get a quote?
Your company name; phone and e-mail; the part's field of use; the reason for coating; quantity; material type; a technical drawing or diameter and length dimensions. Sending photos and dimensions via WhatsApp (+90 533 551 04 21) is enough.
