Abstract

The utility model relates to an electroplate diamond tool equipped with high hardness and high strength matrix material, the coating on the electroplate diamond tool is nanometer nickel material. The method for preparing the electroplate diamond tool comprises the preparation of the electroplating solution, the treatment before electric plating, and the process of the electric plating; during the electric plating, the pulse plating method is adopted, and the electroplating solution is made of NiSO4 is multiplied by 7H2O,NiCl2 is multiplied by 6H2O, H2BO3, refined addition agent, and sodium dodecyl sulfate; the refined crystal grain is easy to obtain by matching the electroplating solution adopted by the invention with the impulse current measures, thereby, the Nano-crystal material can be obtained, and the non-cohesive diamond grain can be inlayed and consolidated in the coating, and the diamond cutting tool for different machining material can be prepared; the preparing method also has the advantages that the manufacturing cycle of the tool is shortened, and the cost is reduced.

Description

technical field [0001] The invention belongs to an electroplated diamond tool, in particular to an electroplated diamond tool with high hardness, high strength and high wear resistance carcass material; meanwhile, it also relates to a manufacturing method of the tool. Background technique [0002] Diamond has extremely high hardness, tools made of diamond are suitable for processing hard and brittle materials, and the use of electroplating technology to prepare electroplated diamond tools not only has a low manufacturing temperature, but also avoids high temperature damage to diamonds, increasing the service life of such tools; Improve tool processing efficiency and processing quality; At present, electroplated diamond tools have been widely used in industrial fields such as machinery, electronics, construction, drilling, and optical glass processing. However, the current production of electroplated diamond tools not only has a long manufacturing cycle, but also the hardness...
