天然单晶金刚石与钢体的焊接技术长期来是国内外的技术难题之一,至今天然单晶金刚石工具均仍采用铆焊、孕镶、电镀及机械夹固等方法将金刚石与钢体连接起来,其实质仍是以各种不同形式用金属将金刚石的大部份包裹着,而仅仅暴露一小部分金刚石在钢体外使用,这不但使天然金刚石工具价格昂贵,而且还经常发生 Natural single-crystal diamond and steel welding technology has long been one of the technical problems at home and abroad, so far natural single-crystal diamond tools are still using riveting, impregnation, plating and mechanical clamping and other methods to connect diamond and steel , The essence of which is still to wrap most of the diamond with metal in a variety of different forms and to expose only a small portion of the diamond to the outside of the steel which not only makes natural diamond tools expensive but often occurs
