摘要
Tool wear and wear mechanism during the turning of a wear-resisting aluminum bronze have been studied. Tool wear samples were prepared by using M2 high-speed steel and YW1 cemented carbide tools to turn a novel high strength, wear resisting aluminum bronze without coolant and lubricant. Adhesion of workpiece materials was found on tool’s surface. Under the turning condition used in this study major wear mechanisms for turning aluminum bronze using M2 high-speed steel tool are diffusion wear, adhesive wear and plastic deformation and shear on the crater. Partial melting of high-speed steel on the rake plays a role in the tool wear also. Major wear mechanisms for turning aluminum bronze using YW1 cemented carbide tool are diffusion wear, attrition wear and sliding wear. To control the machining temperature is essential to reduce tool wear.
