Abstract
The influence of the electrolyte composition and the deposition mode on the composition and microstructure of Fe–Ni–C–Cr electrochemical coatings has been studied. It is shown that an increase in the concentration of chromium chloride in the electrolyte and the current density in the considered range of values leads to an increase in the chromium content in the coatings and their microhardness. In the range of current densities of 60–160 mA/cm2, Fe–Ni–C–Cr coatings with a dendritic surface microrelief are formed. The coating structure contains carbon in the form of films and ultrafine particles as well as dispersed particles, including those with a high chromium content. The content of these phases in the coating structure increases with increasing current density. The mechanism of electrocrystallization of coatings is considered.
