Diamond‐like carbon (DLC) coatings are getting new trends for cutting tool applications. In this research work, the DLC coatings were deposited on 15 × 15 × 5‐mm tungsten carbide cobalt substrates with variation of bias voltage from 0 to 500 V. The DLC films of 400 nm were deposited using filter cathode vacuum arc system, and 100‐nm chromium interlayer was deposited by sputtering. The optimized conditions for plasma pretreatment at different argon flow rates and deposition rates with bias… 

Effect of substrate bias on the tribological behavior of ta-C coating prepared by filtered cathodic vacuum arc

Tetrahedral amorphous carbon (ta-C) films were coated on the tungsten carbide cobalt by using filter cathodic vacuum arc (FCVA). All the specimens were coated at different bias voltage, such as 0 V,
