  • ABSTRACT: This paper presents preliminary results about the influence of the technological parameters – voltage and anode jackets on the microstructure, microroughness, and microhardness of cobalt coatings deposited on titanium alloy Ti-6Al-4V using brush plating. SEM and EDS analysis were used to study the structure and morphology of the obtained coatings. It was found that the cover material of the anode affects the microroughness of the coatings in the range from Ra = 0.028 μm to Ra = 0.039 μm. Changing the voltage from 8V to 12V was found to affect the microhardness of the coatings between 495 HV and 600 HV. Visual control and bend tests were performed to verify the adhesion strength of the brush-plated cobalt coatings
