摘要：
In order to study the tribological properties of sealing materials for dry gas seals, the tribometer equipped with a rotating module was used to investigate the friction and wear characteristics of three kinds of antimony impregnated graphite when paired with pressureless sintered SiC and 3D-printed SiC under dry friction conditions. The effects of velocity and load on the friction and wear characteristics of sealing materials were analyzed, and the wear mechanisms on the surface of mating materials were revealed. The results show that the friction coefficient and wear rate gradually decreases with the increase of the product of load p and velocity v (pv value). When the pv value is low, the wear mechanism is severe abrasive wear and slight adhesive wear. When the pv value is high, the wear mainly occurs between the graphite transfer layers adhered to the silicon carbide friction surface, and the wear mechanism is mainly adhesive wear. In order to study the effect of pv value changes on the friction and wear characteristics of antimony impregnated graphite and silicon carbide sealing materials, the testing program which changes the velocity while fixing the load is preferable. © 2024 Materials China.
