High-pressure phase transitions of B1 structured transition-metal carbides (TiC, ZrC, HfC, VC, NbC, TaC) were systematically researched by ab initio calculations. It was found that these carbides unde...
在刀具前刀面月牙洼磨损区域加工装填MoS2固体润滑剂的微孔,制备了一种镶嵌固体润滑剂的自润滑刀具(SLT-1),并与前刀面有孔但无固体润滑剂的刀具(SLT-2)以及传统刀具(SLT-3)进行切削对比试验。用TH5104红外热像仪测试了3种刀具切削45号淬火钢的切削温度变化规律。结果表明:SLT-1自润滑刀具的切削温度明显降低,比传统刀具SLT-3降低15%~20%,SLT-2刀具比SLT-3降低5...
