Application features of microarc oxidation technology

The technology of microarc oxidation valve metals is one the promising methods for engineering working surface friction units modern technology. As a result versatility technology, it possible to obtain composite ceramic coatings and materials various types. Their properties are set by electrical modes material formation, chemical composition electrolyte, further modification matrix with micro- nanosized tribofillers. Based on practical results their research in field creating types oxidation, an analysis given main areas application microplasma electrolytic advantages over other modification, structure obtained. It distinguish part method order increase its hardness wear resistance. Good were obtained increasing resistance hardened spinning machine parts, number equipment repairs was reduced more than 20 times. use preparation coatings, which solid lubricating dispersed particles embedded. forming aluminum, modified magnetite, graphite molybdenum disulfide, has been developed. According comparative tribotechnical tests, found that intensity linear filled MoS2 3 times, Fe3O4 - 1.6 times lower without filler. original developed obtaining mineral-ceramic material, aluminum oxide diamond inclusions. Abrasive wheels made from this have consistently high volumetric cutting ability, 1.5-3.5 higher traditional analogues characterized retention. possibilities not yet fully explored, most direction being creation nanostructured specific technological task.
