【摘要】 本文对Ａｌ２Ｏ３／ＴｉＣ陶瓷刀具材料切削加工Ｇ４３３５Ｖ高强钢时的切削性能和耐磨性进行了试验研究。结果表明：在低速切削条件下，Ａｌ２Ｏ３／ＴｉＣ陶瓷刀具和硬质合金刀具（ＹＴ１５）的抗后面磨损能力相差不大，而在高速切削条件下，前者的抗后面磨损能力远高于后者。Ａｌ２Ｏ３／ＴｉＣ陶瓷刀具前面的磨损形式主要为粘结磨损，后面的磨损形式主要为磨粒磨损。更多还原

【Abstract】 The machining performance and wear mechanism of the Al2O3/TiC ceramic cutting tool in continuous turning of G4335V high strength steel were examined. Resultsshowed that at lower cutting speed, the flank wear resistance of the Al2O3/TiC tool was almost the same as the cemented carbide tool (YT15), while at high cutting speed, the Al2O3/TiC tool exhibited much more improved flank wear resistance compared to cemented carbide tool.Adhesion and abrasion wear were found to be tile diminant wear mechanism.更多还原
