硬质合金已在诸多领域广泛应用.WC-Co和WC-Ti(W)C-Co类合金矿山钻采工具和金属切削刀具在使用中因韧性差导致崩刃脆断及因强度耐磨性低造成过早磨损失效,在许多场合已经不能满足使用要求.寻求改善其性能与使用寿命的方法愈发成为迫切需要.
Carbide has been widely used in many fields.WC-Co and WC-Ti (W) C-Co alloy mining and mining tools and metal cutting tools in use due to poor toughness caused by chipping brittle fracture and due to strength and wear resistance Low premature wear and tear failure, in many cases can no longer meet the requirements of use.It is increasingly urgent to find ways to improve its performance and service life.
