Abstract
The paper presents the results obtained when studying the properties of copper electroplated coatings prepared at the L1-210 v2 (Italy) galvanizing plant using bright copper plating electrolyte by the «24 Carats» company (Moscow) and addition of the electroerosion copper nanopowder prepared by the electro erosion dispersion (EED) method from copper wire scrap in distilled water. An original unit developed by the authors (Russian Federation Patent 2449859) was used for EED conductors. Values of the friction coefficient and wear factor obtained in coatings tests at the Tribometer automated friction machine (CSM Instruments, Switzerland) showed no significant differences in wear resistance of samples. The hardness tests on sample surfaces were carried out using the DM-8 automatic micro hardness tester by the Micro Vickers method with the 25 g indenter load for 10 indentations with random indentation points in accordance with GOST 9450-76. Indenter loading time was 15 seconds. It was found that microindentation hardness of the copper coating with added copper nanoparticles is 15% higher than that of the steel substrate and the sample with the standard copper coating.
