深冷处理提高YW1硬质合金刀片耐磨损性能的机理研究

Study on Mechanism of Improving Wear-Resistibility of YW1 Carbide Inserts by Deep Cryogenic Process

研究了深冷处理可显著提高YW1硬质合金车刀片耐磨损性能的内在机理 。

The internal mechanism that the deep cryogenic process can improve obviously the wear resistibility of YW1 carbide turning inserts is researched. It is found that the main reason of improving the wear resistibility of YW1 inserts by the deep cryogenic process is the completely α Co→ε Co multi type martensitic phase transformation in YW1.
