高速干切削淬硬AISIH13钢的硬质合金刀具（YW2）磨损机理
Wear Mechanism of Cemented Carbide Cutters （YW2） in High-peed Dry Machining of Hardened AISIH13 Steel
摘要
Abstract
High-speed dry machining （HSDM） technology must be developmental trend of mechanical manufacturing field. HSDM tests of hardened AISIH13 were performed with YW2 ,SEM and EDS were used for inspection of morphology and analysis of element;respectively, and tool wear mechanism was investigated. The results indicated that temperature gradient is essential reason of tool wear. The rake surface takes on irregular concave, adhesive wear is leading wear pattern, the relief surface presents small inclined plane, fatigue exfoliation is dominating. Meanwhile, oxidation reaction and element diffusion exist in rake and relief surface, too.关键词
