用新研制的Ni基、Ni W基涂层刀片与未涂层刀片进行了高强度合金钢的对比车削试验和切削性能研究 ,结果表明 ,新型涂层刀片切削性能良好 ,磨损较小 ,耐用度提高。通过适当研磨Ni基涂层刀片的前刀面 ,可有效提高刀片涂层的抗剥落能力 The comparative research on cutting and cutting performance of high strength alloy steels with Ni-based and Ni-W coated and uncoated inserts was carried out. The results show that the new coated inserts have good cutting performance with less wear and durability improve. By properly grinding the rake face of the Ni-based coated blade, the blade coating is effectively improved in its resistance to spalling
