Research on the Wear Characteristics and Wear Mechanisms of CrAlTiN Coated HSS Tools under Dry Cutting Conditions

Abstract:

High-speed steel (HSS) turning tools was designed and sharpened according to the angles of the complex shape cutting tools. CrAlTiN coating was deposited using unbalance magnetron sputtering plating technique. By dry turning tests, the wear characteristics and wear mechanisms of the face were investigated. The results show that the face wear of the coated HSS tools is obviously different from that of the uncoated tools, the crater width is smaller, the boundary is jagged and the lowest position is away from the major cutting edge. Adhesive wear and local adhesive wear are the main wear mechanisms.
