摘要

The increasing freight volumes and the speed of transport, as well as increasing demands with regard to safety have made the search and development of new anti-friction materials a topical task. The main requirements to the bearing assemblies include reliability, durability, simplicity and ease of maintenance. The paper considers the features of the manufacture of braking sliding sleeves/ bushings for transport vehicles made from sintered low-alloy powder materials based on Fe-C-Ni with Ni and Mo contents of 0.3%. The paper presents data on the microstructure of the sintered samples of the products and research of some physical and mechanical properties. Surface quality and friction coefficient were evaluated by surface profiling and tribological tests, correspondingly. Particular attention is paid to the use of ultrasonic testing for quality control of the products.
