【Abstract】 The DLC films with excellent properties were fabricated by optimum deposition of DLC films and transition layers on cemented carbides. Experimental cutting test and indus-trial on-the-spot cutting test showed that the working life of blades with DLC films was obviously longer than those of blades without DLC films in cutting aluminum bronze and eutec-tic aluminum-silicon alloy.更多还原
