用金属镀层作结合剂的金刚石油石、什锦锉之类磨具,使用一段时间之后,由于磨损和磨屑的充填,磨具表面变得异常光滑,而基本失去磨削能力。弃之可惜,用之较差。为此,我们试用酸溶液浸蚀处理磨具表面,使磨屑全部去掉,作为结合剂的金属基体也少量浸蚀,金刚石明显裸露,磨削效果完全恢复。所用溶液成分见表所示。 Diamond coating with a metal coating as a bonding agent, and a type of abrasive tool such as a rasp. After a period of use, the surface of the abrasive becomes extremely smooth due to wear and debris filling, and the grinding ability is almost lost. Unfortunately, the use of poor. To this end, we try etching the abrasive surface acid solution, so that all wear debris removed, as a binding agent of the metal substrate is also a small amount of erosion, the diamond is obviously exposed, the grinding effect completely restored. The solution composition shown in the table.
