Abstract
Abstract
Based on a fully flooded transient non-Newtonian thermoelastic fluid lubrication analysis of representative engineering ceramics and steels with different thermal conductivities and surface roughness, it is found that the material combination that causes the reduction of the maximum film pressure is closely related to the thermal conductivity of the contact materials and the surface temperature of the smooth-surfaced materials, and the maximum pressure reduction method is proposed. The results make a significant contribution to the design of mechanical elements involving contact between materials with different thermal conductivities and surface roughness.
