本文分析和讨论了硬质合金刀片其热电势与磨损的关系．着重研究了YW1硬质合金热电势对刀片后刀面磨损的影响规律和影响程度．并提出了热电势对刀片寿命的影响，从而证明了采用测量硬质合金刀片的热电势来预测硬质合金刀片寿命的可行性．
This paper analyzes and discusses the relationship between the thermoelectric power and wear of carbide inserts. Emphatically studied the YW1 carbide thermoelectric potential of the blade flank wear rule and influence degree. The influence of the thermoelectric power on the blade life is also presented. It proves the feasibility of using the thermoelectric potential of the carbide blade to predict the life of the carbide blade.
