MITSUBISHI MATERIALS U.S.A. COMPANY announced the release of LC2005 - DLC Coated Grade for Turning of Non-Ferrous Metals. DLC coating is a film that possesses both the hardness of diamond and the lubricity of graphite. It is particularly suitable for aluminum alloy machining due to its excellent wear resistance and anti-adhesion properties, especially in cutting tools. Hydrogen-free DLC films have high hardness and provide superior wear and heat resistance, which is why they have been widely used in cutting tools. Generally, while hydrogen-free DLC excels in wear and heat resistance, it faces the challenge of being prone to peeling due to the significant hardness difference from the substrate. Mitsubishi Materials has overcome this issue by adopting a newly developed thin hydrogen-free DLC film with improved adhesion, thereby achieving an excellent balance of wear resistance and strong adhesion.
