Abstract—
The results of experimental determination of the wear intensity coefficient and the friction coefficient in the steel-bronze BrNBT and steel–molybdenum coating contact are shown. To determine the tribotechnical parameters of the coating, experiments were carried out on a Tribometer TRB automated friction machine of the Swiss company ANTON PAAR according to the ball–disk scheme. It is shown that the average coefficient of friction for a sample with a molybdenum coating is almost two times lower than for a sample without a coating. With the help of the SURTRONIC 25 profile meter, a profilogram was obtained to determine the coefficient of wear intensity. At a run of 50,000 m, the coefficient of wear intensity for a sample made of BrNBT material without coating at a maximum contact voltage of 507 MPa is 2.48 × 10–4 mm3/m, and for a sample with a molybdenum coating was 1.98 × 10–5 mm3/m, which is 12.5 times less. Recommendations for the use of a molybdenum antifriction coating are given.
期刊介绍:
Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
