<p>This invention relates to field of treating friction surfaces of friction units by means of modifying friction surfaces, forming wear resistance and defensive coatings, and can be used both in the process of treating new details and friction units and at repair-restoration operations. The main task of the invention is to improve the composition for treating friction pairs, that includes a like abrasive powder prepared on the basis of natural hydrosilicate of magnesium, in which forming a modified hardened surface layer of the given composition strongly connected with a friction surface is possible due to including into the composition an additional mixture of metal powders with abrasive more solid than natural mineral, or a mixture of a metal powder with metal containing admixture and of the same abrasive. The main task of the invention is to improve the method of preparing the composition for treating friction pairs, in which due to a preliminary blending of a metal powder with a powder of more solid abrasive, then than natural mineral, or a blending of a metal powder with metal containing admixture having the same abrasive, and then the following blending of the obtained product with a natural hydrosilicate powder. The usage of compositions for treating friction pairs according to the proposed engineering solution ensures an essential increase of hardness and decrease of wear and friction coefficient, as well as compensation of the lost sizes. It gives grounds to propose these compositions for treating units of machines and mechanisms, both new and second-hand of different extent of wear.</p> |
