The main features of the widespread use of electrolytic chromium coatings are their high chemical resistance and resistance to mechanical wear even with their small thickness. Practically all metal structures protected by electroplating, including chrome-plated ones, are subject to the corrosion process. The main goal in the electrolytic chrome plating process is to maintain the resistance to mechanical wear of the chromium coating. The positive factors causing the preservation of chrome coatings from corrosion damage are the search for new innovative technologies for obtaining particularly resistant chrome coatings. However, even with the high chemical resistance of chromium, complete corrosion protection of hardware products made of iron cannot be achieved. The reason for this undesirable phenomenon lies in the fact that in a pair of chromium-iron, chromium is the anode. Provided that the coating metal is a cathode, then there are favorable conditions for passivation of the base metal and then the coating can protect the base metal not only mechanically, but also electrochemically. To give protective properties to a chrome coating, a preliminary coating of an iron product with another metal is used – copper, nickel, silver, and then a chrome coating. In such cases, it is possible to give strength to the chrome coating even with a thickness of only about The work is devoted to the selection of methods for creating such a surface of the substrate to obtain chrome coatings of a given thickness, non-porous with good adhesion by electrodeposition.
