The relationship between the product of load and sliding speed with friction temperature and sliding wear of a 52100 steel

Abstract

Base on the tests of friction and wear of AISI 52100 steel under the condition of dry sliding, conclusions can be drawn as follos: 1. 1. The wear volume and friction temperature increase with increasing normal load and sliding speed. 2. 2. The wear volume increases with increasing friction temperature, especially when T b ecxeed a certain value, the wear volume increases greatly. 3. 3. Pν = 100N.m/s can be regarded as the critical condition of the transition from mild wear to severe wear during the dry sliding wear of steel, T b can also be regarded as the transition temperature of wear mechanism. 4. 4.The normalized wear rate W ̃ = 13 × 10 −8 can be also regarded as the critical value of the transition from mild wear to severe wear during the dry sliding wear of of the steel.
