摘　　要：分析了CrTiAlN镀层的组织,研究了CrTiAlN镀层对M2高速钢刀具切削性能的影响．结果表明:CrTiAlN镀层提高了M2基高速钢刀具的切削性能．CrTiAlN镀层具有良好的高温稳定性能,能避免红硬性不足引起的刀具失效;CrTiAlN 镀层与M2基体的结合较强,具有稳定结构,能避免抗压强度下降引起的刀具失效．The cutting performance and mechanism for HSS twist drills with CrTiAIN coating were investigated in this paper. The results show that this CrTiAIN coating possessed stable mechanical properties including hardness, adhesion and wear resistance in high temperature due to the well thermal stability in morphology, microstructure and phase etc of coating. Therefore, enough cutting force is ensured for working in the severe cutting condition such as for dry cutting high strength steel.
