چکیده
In this study, different amounts of MoS۲ particles and an anionic surfactant were added to the conventional chromium electroplating bath in order to electrodeposite crack-free chromium coatings and the structure, morphology, tribology and corrosion behavior of the deposited coatings were investigated using X-ray diffraction spectroscopy, scanning electron microscopy, pin on disk wear test method, dynamic polarization, and electrochemical impedance spectroscopy techniques, respectively. The results showed that the incorporation of MoS۲ particle into the electrodeposited Cr coatings is impossible and no chromium coating can be electroplated from baths containing more than ۵ g/L MoS۲ particles. In addition, as the MoS۲ concentration in the bath increases up to ۱ g/L the corrosion and wear resistance of the deposited coatings increases. Moreover, those coatings that were electroplated from the baths containing more than ۱ g/L exhibited less performance regarding their corrosion and wear behavior.کلیدواژه ها
