Abstract

Задачей изобретения является повышение физико-механических свойств покрытий, использующихся в узлах трения скольжения, а также расширение области применения газотермических покрытий. Изобретение относится к технологии восстановления и упрочнения поверхности деталей узлов трения скольжения методом газотермического напыления, а именно гиперзвуковой электрометаллизацией. Способ включает нанесение газотермического покрытия методом гиперзвуковой электрометаллизации двух проволочных сталей. В качестве материала одной проволоки используют хромсодержащую сталь с содержанием хрома до 25 мас.%, а в качестве другой проволоки используют алюминиевый сплав с содержанием алюминия не менее 80 мас.%, причем ее диаметр выбирают в зависимости от количества хрома в стальной проволоке. Способ позволяет повысить износостойкость детали на 15-25%.The objective of the invention is to improve the physical and mechanical properties of coatings used in sliding friction units, as well as to expand the field of application of thermal spray coatings. The invention relates to a technology for restoring and hardening the surface of parts of sliding friction units by the method of thermal spraying, namely, hypersonic electrometallization. The method includes applying a thermal spray coating by the method of hypersonic electrometallization of two wire steels. As the material of one wire, chromium-containing steel with a chromium content of up to 25 wt.% Is used, and as the other wire, an aluminum alloy with an aluminum content of at least 80 wt.% Is used, and its diameter is selected depending on the amount of chromium in the steel wire. The method allows to increase the wear resistance of the part by 15-25%.
