几年来我国的地质勘探事业得到了巨大发展，地质勘探设备大量增加，设备的检修任务也相应的增加。目前对检修所需的另配件存在着供不应求的情况下，利用堆焊方法以恢复钻探设备的零件而节约钢材是具有很大的现实意义的，尤其是野外队的检修工作在现阶段条件下这是一种切实可行的方法。在机件磨损表面上堆焊耐磨合金是提高被修复机件的使用寿命及节约优质钢材最有效方法。由于合金
Over the past few years, China’s geological exploration has made tremendous progress, a substantial increase in geological prospecting equipment, equipment maintenance tasks also increased accordingly. At present, there is a shortage of spare parts required for maintenance, the use of surfacing methods to restore the drilling equipment parts and save steel is of great practical significance, especially the field team maintenance work at this stage under this condition Is a practical method. Wear-resistant alloy surfacing on the wear surface is to improve the service life of repaired parts and save the most effective method of high-quality steel. Due to the alloy
