Introduction to surface coatings for carbide products

Carbide products, primarily composed of tungsten carbide (WC) and titanium carbide (TiC) with a cobalt (Co) binder, are renowned for their exceptional hardness and durability. Manufactured through advanced powder metallurgy techniques, these tools are sintered in specialized furnaces such as vacuum or hydrogen reduction furnaces to achieve their desired properties.

High Performance at High Temperatures

One of the standout characteristics of tungsten carbide alloys is their ability to maintain formidable hardness even at elevated temperatures, typically ranging from 850 to 1000°C. This attribute allows carbide cutting tools to operate at cutting speeds significantly faster—approximately 4 to 10 times—than those made from high-speed steel.

Exceptional Hardness

carbide products boast an impressive hardness range from HRA 85 to 95, making them ideal for various demanding cutting applications. This high hardness level ensures prolonged tool life and enhanced performance in cutting operations.

Enhancing Carbide with Surface Coatings

To augment the already impressive wear resistance of carbide products, surface coatings have been developed. These coatings involve applying a thin layer of extremely hard and wear-resistant materials such as titanium carbide (TC) and titanium nitride (TiN) to the surface of the carbide. Typically, the coating thickness varies from 5 to 12 μm, providing a critical balance where the base material contributes strength and toughness, while the coated surface offers increased resistance to wear.

Benefits of Coated carbide products

Enhanced Wear Resistance: The primary advantage of surface coatings is significantly enhanced wear resistance, which extends the tool’s operational life and maintains its cutting efficiency longer than uncoated tools.
Improved Performance: Coated tools are particularly beneficial in semi-finishing and finishing operations where precision and tool longevity are crucial.
Cost-Effectiveness: Although initially more expensive, the longer lifespan and reduced need for frequent replacement make coated carbide products more cost-effective in the long run.
