To activate the surface of cotton fabrics before chemical nickel plating, it is proposed to use physical and chemical processes occurring in thin layers of solutions of copper (II) chloride under the influence of electromagnetic solar rays of the visible spectrum. It is shown that cellulose, which is the main component of the fabric, undergoes photo-oxidation in the presence of copper (II) chloride. As a result of this interaction, well-bonded copper monochloride is formed. When further processing of the fabric with phosphine gas, copper monochloride is transformed into copper and copper phosphide. Copper phosphide is a catalyst for the chemical nickel plating process. This makes it possible to obtain an electrically conductive nickel-phosphorus coating on the surface of the fabric in conventional electrolytes of chemical nickel plating. It is also found that when screening individual sections, the processes leading to the formation of copper monochloride do not occur. This allows selective metallization of the fabric.

Activation of the surface of cotton fabrics before chemical copper plating is proposed to be carried out by applying dispersed copper particles. For this purpose, physical and chemical processes that occur in thin layers of copper chloride solutions under the influence of electromagnetic solar rays of the visible spectrum are used. Initially, copper chlorides interact with cellulose, which is the main component of the tissue, and form copper monochloride. It is shown that this interaction is stimulated by solar rays. After that, the fabric is moistened with a solution of ascorbic acid and again exposed to sunlight. Under the action of photons of solar radiation, electrons in a semiconductor acquire additional energy and restore copper to the elemental state, and the vacancies formed are filled with electrons due to the oxidation of ascorbic acid. As a result of these processes, a film is formed on the surface of the tissue containing copper particles that can catalyze chemical copper plating.

“…Upon receipt of composite coatings such as graphite-copper, carborund-copper increases electrical conductivity, resistance to friction, does not oxidize when interacting with oxygen in the air, chemically attaches to all aggressive aqueous solutions compared to precious metals, and reduces the coefficient of friction. [7][8][9] The main objective of the study is to obtain a coating of modified nickel phosphide with high wear resistance and low friction coefficient by incorporating into the composition of nickel phosphide a Ferro phosphoric powder, which is an auxiliary product of production.…”

The article presents the results of research on the production of chemical films of nickel phosphide with the addition of some impurities such as ferrophosphorus and carborundum. Magnetic stirrer and purge method were used for research. As a result of the study, when analyzing the quality and composition of the obtained films, it was found that the quality of the films obtained by purging is high. With the help of scanning electron microscopy, the quality of the obtained film was analyzed, the elemental composition was determined.
