摘要
Abstract
The friction and wear properties of brake shoe affect directly the safety operation of high-speed train.The friction and wear characteristics of train brake shoe materials made by powder metallurgy with copper-based powder under brake pressure conditions are tested by using friction testing machine.The results show that the friction coefficient and surface temperature present an increasing trend with the increase of brake pressure obviously.The oxide film formed under 8 MPa brake pressure has lubrication effect,which make the friction coefficient stable.关键词
