摘要
Abstract
Microstructures of ultra-high carbon steels under different heat treatment conditions and effects of sliding speed and load on abrasive wear properties of materials were studied. The results show that the microstructures turn from network carbides and lamellar pearlites as cast condition into spheroidised pearlites after spheroicizing annealing. The microstructures after normalizing are mainly consisted of lamellar pearlites and granular carbides. After quenching and lonnealing, the tempered martensites are formed. The friction coefficients of materials decrease with the increasing of sliding speed and load. The wear rates increase with the load increasing and sliding speed decreasing. The friction coefficient and wear rate of ultra-high carbon steels after quenching and lonnealing is notably lower than that after spheroicizing annealing at the same conditions.关键词
