Universal phase transitions of B1 structured stoichiometric transition-metal carbides
Universal phase transitions
2010/11/23
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...
镶嵌固体润滑剂的自润滑刀具切削温度研究（Cutting Temperature of Cemented Carbides Base Self-lubricated Tool Embedded with Solid Lubricants）
干切削 切削温度 自润滑刀具 摩擦磨损特性
2010/1/28
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...
