Coating For Dry Machining Of Al Alloys
Engineers from Sumitomo Electric Industries have developed a diamond-like carbon coating (DLC) for the dry machining of aluminum alloys and nonferrous applications. Previously, in the first stages of harsh-environment cutting, coatings would peel and lose their beneficial properties.

Engineers from Sumitomo Electric Industries have developed a diamond-like carbon coating (DLC) for the dry machining of aluminum alloys and nonferrous applications.
Previously, in the first stages of harsh-environment cutting, coatings would peel and lose their beneficial properties. The company claims that with the coating, cutting tools maintain their properties, including high hardness, excellent lubrication, low friction coefficient, smooth surface, corrosion resistance and increased tool life. The coating is designed to promote chip control and has a friction coefficient of µ=0.05 - 0.2—without lubricants. Aluminum alloy adhesion on the edge is suppressed in dry machining, thereby decreasing cutting resistance. Furthermore, generation of built-up edge is suppressed, thereby maintaining the sharpness of the edge and improving the quality of the cutting material. The coating can be found on the company’s carbide grades, drills and end mills.
