Development of composition coatings for powders of superhard materials (shm) on glass-like binding basis and on natural clay-containing mineral basis for serviceability rise of abrasive tools

There the choice criterion of binding of glass-composition materials has been suggested; the phase equilibrium for the different glass-clay-containing mineral systems have been determined; it is stated, that the refractory oxydes, which is formed by the dehydration of clay-containing minerals, is dissolved in the glass partially and is built in its structure, forming the strong framework; that rises the wear resistance and heat resistance of composition. The compositions and the fashions of application of composition glass coatings on the SHM powders; the new production process of composition glass coatings of SHM powders, which excludes the victual use have been developed. The production processes of composition glass coatings have been introducedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
