Abstract
Currently, there are various electrolytes for the electrochemical deposition of copper coatings. The most used of them in industry for direct coating of steel are cyanide electrolytes. Obviously, the use of cyanide electrolytes is undesirable due to their high toxicity. In a number of countries, including the Russian Federation, standards have been established that prohibit or strictly regulate the use of cyanides in various technological processes. This study’s outcomes are connected with the development of an alternative alkaline copper plating electrolyte based on hydroxyethylidene diphosphonic acid to replace toxic cyanide solutions.
The study has shown that the proposed electrolyte based on hydroxyethylidene diphosphonic acid is capable of ensuring to obtain copper coatings that are not only of high quality but also demonstrate adhesion strength to the steel base.
These results open up new vistas for the development of safe and effective alternatives to cyanide electrolytes in electrodeposition processes of copper coatings, helping to reduce the environmental load and improve the safety of technological processes in industry.
