Ezperimental Research on Wear Resistance of Deep Cryogenic Treated HSS Twist Drill

摘要：

On the base of deep cryogenic treatment(DCT) and drilling experiments of W9Mo3Cr4V, W6Mo5Cr4V2 and W4Mo3Cr4VSi HSS twist drills, the influence of deep cryogenic treatment on hardness, wear resistance and microstructure was studied. The experimental results indicated that deep cryogenic treatment induced transformation of retained austenite to martensite and formation of fine carbide particles, so the toughness, wear resistance and hardness values of HSS twist drill were improved. Life of DCT drills was 2 to 4 times more than untreated drills.
