The combined corrosion-wear degradation of nano-structured Ni–SiC coatings in sliding contacts immersed in electrically conductive solutions is investigated in situ by electrochemical techniques (open-circuit potential measurements, E OC , the potentiodynamic polarization measurements, PD, and the electrochemical impedance spectroscopy). The coating thickness was 50μm, with an average volume...
The dependence of the tribocorrosion of stainless steels AISI 304L and SS 3M ® orthodontic archwires sliding against corundum in a Ringer's solution on applied normal force, and sliding velocity, has been investigated using in situ electrochemical noise measurements. Applied normal force and sliding velocity were found to greatly affect current and potential during fretting-corrosion. An increase...
Tribocorrosion of stellite 6 in sulphuric acid was studied with a pin-on-disc tribometer through test conditions of intermittent friction. The occurrence of a mechanism involving mechanical depassivation during friction and further repassivation during the latency period between two successive friction steps was demonstrated. Polarization curves measurements and wear measurements by weight loss together...
