Результаты компьютерного моделирования позволили определить лучшие геометрические характеристики оснастки, обеспечивающие требуемые геометрические параметры качества гальванического хромового покрытия детали «Кулак» и, как следствие, обеспечить необходимый ресурс работы узла передней подвески автомобиля УАЗ.

Complex shape parts, for example a steering knuckle, were taken as objects of study. Coating deposition was performed by immersion. Optimal modes for the chrome coating process were chosen. Based on these modes the influence of the anode equipment design on the distribution of current lines over the part surface as well as on the formed coating thickness was studied. Two types of anode equipment used in chromium-plating of such parts are described in the paper: a cylindrical anode placed in alignment with the part, and two segment anodes placed on the sides. Computer models of coating thickness distribution over the part surface for the above anodes under identical electrolysis conditions are developed. Advantages and disadvantages of both anode devices were identified during the study. The results obtained make it possible to estimate the coating thickness deviation in different areas of the cathode and to determine the anode optimal structure to solve the problem of increasing the service life of the steering knuckle – ferrule friction unit.
