Electroplated diamond tool is a kind of diamond tool made by metal electrodeposition, which is made of matrix (steel or other material) firmly by matrix metal. It is widely used in mechanical electronics, glass, building materials, oil drilling and other industries. With the development of economy and the progress of science and technology, the requirements for electroplated diamond tools in different industries are basically the same, that is, high efficiency, long life and high grinding precision. To ensure these properties, the coating metal should not only have high hardness and wear resistance, but also need to be evenly distributed in each part of the matrix so as to avoid the loss of the coating to shorten the tool life. In some special industries, such as the strong grinding of magnetic material industry, the feed volume is around 0.3mm, and the dry grinding of the large intake of the ceramic industry is particularly demanding for the bonding force between the metal and the steel matrix. In the production process of electroplated diamond tools, most manufacturers have only noticed the types, hardness and wear resistance of the coated metal, and often ignore the bonding force between the metal and the substrate. In practice, the phenomenon of coating shedding is common.
