Tool Coatings
Tungsten Carbide, Di-Carb, and Plasma Coating
Tools with surface coatings have a longer shelf life and are more effective at getting the job done. For over 40 years, Tunco has been an industry leader in producing crushed tungsten carbide products, and we now also develop hard-facing coating and ceramic coatings for tools used in high-production industry applications. We’re also capable of recoating any existing part, regardless of whether we manufactured it.
Tunco Tool Coating Options
When choosing a coating for tools, it is important to consider the hardness of the materials and wear resistance capabilities based on the use of the tool. Our team of industry experts is here to assist you with coatings solutions for your specific need.
Tungsten Carbide
Tungsten Carbide (WC) is a chemical compound that combines equal parts tungsten and carbon, making it stronger than steel or titanium. Tungsten carbide measures 90 on the Rockwell “C” scale, which approaches the hardness and durability of natural diamonds. The benefits of a tungsten carbide coating include:
- Improves part performance and wear resistance
- Reduces costs on wearable parts
- Decreases machine downtime for part change-outs
- Allows the freedom to design less expensive or lighter weight materials
In its basic form tungsten carbide is a fine, gray powder that is extremely sharp. Our expertise comes into play when this chemical compound is transformed into a form that can then be placed on cutting, sanding and grinding tools. We do this by utilizing a brazing process with a controlled atmosphere furnace to permanently bond the compound particles (grit) to the metal tool part.
Di-Carb
The Di-Carb coating is a Tunco original that uses patented technology to combine the durability of natural diamonds with the extreme sharpness of tungsten carbide. This creates a diamond-like coating for a fraction of the cost. The Di-Carb technology is specifically designed for use with cutting tools. This material is designed to create a long-lasting, rapid cutting saw blade for high-production applications.
Plasma Coating
Plasma coating is a thermal spraying system used to coat metal tools, capable of coating metal sizes from 1/16” to 65”, operating at 35,000 degrees Fahrenheit. We specialize in providing plasma coating that ranges from 400 mesh to 60 mesh with materials such as carbide, ceramic, stainless steel, and aluminum oxides.
Benefits of Plasma Coating include:
- Protects from corrosion
- Wide selection of coating options
- Wear-and-tear resistance
- Heat-resistant
- Applicable to a wide range of materials
