Matrix wear-resistance of diamond saw blade

According to sawing experiments with single saw blade, the relationships of wear-resistance and high-temperature hardness of four matrix formulations were investigated, and the concept of matrix softening at high temperature was put forward. Based on measuring the matrix softening points at high temperatures, the relationship between wear resistance and softening point was analyzed. The experimental results show that the softening point can reflect the property of wear-resistance of the matrix; choosing an appreciate matrix formulation could improve the work life of diamond saw blade by 20% to approximately 30% under the same conditions of diamond parameters and rock.
