Abstract
For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Electrochemical methods have found their greatest usefulness in the dimensional machining of surfaces of machine parts, based on complex processes of metal dissolution. The authors study the results of bench tribological tests of the results of application of the combined method of diamond electrochemical honing and galvanic chroming, creating high-strength surface layers, that showed the measure of intensity of wear, deviation from the optimum regimes, the causes and nature of emergence of coating defects. To fulfill the test conditions, appropriate equipment, technological equipment, tools were used, and an appropriate type of electrolyte medium was provided. The structure of the created equipment, in particular, included modernized vertical honing semi-automatic machines and mechanical devices. Based on the test results, the possibility of combining two methods of electrochemical metal surface treatment subject to high tribological load was confirmed. Keywords: machine parts, tribology, combined treatment, electrochemical processing, diamond electrochemical honing, galvanic chroming, wear, dimensional machining.
