The Use of Alumina Nanoparticles as Modifiers of Galvanic Binder of Diamond Tools

Abstract:

This article presents results of a study of the surface topography of nickel composite electrochemical coatings (CEC), reinforced alumina nanoparticles, and the test results of the diamond tool. Used as a reinforcing phase alumina nanopowder was obtained by electrical explosion of aluminum wire in oxygenated atmosphere and had an average particle size of 60-70 nm. Experiments showed that the inclusion of alumina nanoparticles in a nickel matrix modifies its structure and increases the strength properties, so the wear resistance of diamond-plating increased by 3 times.
