The type of coating off
2012-12-07 by seoer10

Electroplated diamond tool during use, due to the conditions of use, such as the size of the grinding force, the impact of the temperature rise, the workpiece and other reasons, will cause the separation phenomenon of the diamond-containing metal plating layer and the steel substrate, which is the coating off. The coating off generally partial loss, plating a one-time full-peeling rare phenomenon. In the actual use of the process, the coating off the case generally have the following three:

1) the coating off the surface of the base body: the diamond-containing metal plating layer and the metal substrate of the non-diamond coating and steel substrate at the same time separating.

Layer (2) falling to the coating of the metal substrate: that the metallic base coating and the steel substrate of the diamond-free unseparated, only the diamond-containing metal plating layer and the metal primer coatings peeling.grinding wheel

The diamond-containing metal plating layer (3) separated from the plating metal layered: a diamond-containing metal plating layer in contact with the workpiece during use, parts of the metal coating is not normal wear, and the non-normal shedding into a piece or powdered, diamond all off, but local granular shedding. This phenomenon is not easy to draw attention to the consequences of the products have shorter lifespans, often give people a false impression of poor gripping force or wear resistance of the coating metal. Exclude thicker coating charred and poor factors of the wear resistance of the coating metal, the tool during normal use, the diamond particles shedding visual representation of the surface of the abrasive tools continuously into a piece of the larger holes, it should be the shedding of such coating.
