本文重点研究了碳化钨与粘结金属的配合比例、碳化物颗粒的粒度、粘结金属的组织成分及其硬度等因素对喷焊层耐磨性的影响,并初步得出某些因素对喷焊层耐磨性的影响规律。还对碳化钨喷焊层在静载与动载磨粒磨损条件下的表面形貌进行了细致地观察与分析,并对磨粒磨损的机理进行了探讨,为正确地选用碳化钨喷焊层提供了依据。
This article focuses on the tungsten carbide and the binding metal ratio, the particle size of carbide particles, the composition of the bonding metal and hardness and other factors on the wear resistance of spray coating, and initially concluded that certain factors on the spray The influence law of wear resistance of welding layer. The surface morphology of tungsten carbide spray coating under static and dynamic abrasive wear conditions was also carefully observed and analyzed, and the mechanism of abrasive wear was also discussed. In order to properly select the tungsten carbide spray coating Provided the basis.
