摘      要：The temperature of a friction pair exerts considerable influence on the tribological behavior of a *** two cases,one with and the other without Cu(copper)nanoparticles,the temperature increase in friction pairs caused by frictional heating and its tribological properties at various temperatures are studied by using the molecular dynamics *** results show that temperature distribution and surface abrasion are significantly improved by the presence of Cu *** is one of the reasons for the improvements in tribological properties achieved in the presence of *** temperature and range of influence of frictional heating for the model without nanoparticles are significantly increased with the increase in the sliding velocity;however,in the model with nanoparticles,the temperature gradient is confined to the area near the Cu *** an increase in the temperature of the friction pair,the improvement in anti-wear properties associated with the presence of Cu nanoparticles becomes more significant.
