COBALT-FERROUS RATIOS FOR ENHANCED CORROSION AND WEAR RESISTANCE OF ELECTRODEPOSITED COATINGS ON 316 STAINLESS-STEELS

Popis výsledku v původním jazyce

This study investigates the enhancement of wear and corrosion resistance of 316 stainless steels through Co-Fe electrodeposited coatings at varying ratios (50:50, 75:25, 95:5). The 50:50 Co-Fe ratios produced a uniform, defect-free coating with a thickness of 35 mu m and a body-centered cubic (BCC) microstructure. Electrochemical tests, including Tafel and Nyquist plots, revealed superior corrosion resistance for the 50:50 ratio, with a low corrosion rate of 0.0037 mm/year, a corrosion potential (Ecorr) of-259.534 mV, and a corrosion current density (Icorr) of 12.752 mu A. Tribological evaluation indicated the highest wear resistance, with the longest wear time (1082 seconds) and the lowest coefficient of friction (0.29). These findings highlight the potential of Co-Fe coatings for aerospace and marine applications, particularly in components exposed to harsh mechanical and corrosive environments. The study also emphasizes the novelty of cyclic voltammetry as a precise method for optimizing electrodeposited coatings.
