盘式钻头齿面强化试验

ENHANCEMENT TEST ON THE DISC BIT

用球状烧结碳化钨取代粒状铸造碳化钨 ,加入一定量的自熔性合金 ,自制薄管焊条 ,分析了焊条的组成、性能和耐磨性。并对盘式钻头进行齿面强化试验。研究表明 ,自制薄管焊条流动性好 ,耐磨性高 ;盘式钻头齿面强化后 。

By replacing the granular casted carbonization tungsten with spherical sintered carbonization tungsten, filling quantitative of self fluxing nature holly, the thin metal wall welding rod was made. Meanwhile its component, the character and the wear resisting was analyzed. Finally, the disc bit is tested that was enhanced by the welding rod. The conclusion is that the welding rod mobility and wear resisting are better than those before, and the disc bit′s well drilling effect is outstanding after the reinforcement.
