宽温域条件下超细晶WC-6Co硬质合金摩擦磨损性能:钛合金和轴承钢摩擦配副的影响
Tribological Properties of Ultrafine-grained WC-6Co Cemented Carbide over a Wide Temperature Range:Influence of Titanium Alloy and Bearing Steel Counterparts
摘要
Abstract
An ultrafine-grained WC-6Co cemented carbide was fabricated via spark plasma sintering.The influence of their counterparts on the tribological properties of ultrafine-grained WC-6Co cemented carbides over wide temperature ranges was investigated.When sliding against the TC4 titanium alloy,the ultrafine-grained WC-Co cemented sample exhibits a low friction coefficient and negligible wear from 25 to 300 ℃,which is dominated by mild adhesive wear mechanisms.At 500 ℃,intensified adhesive wear coupled with oxidative wear occurs,leading to a rapid increase in the friction coefficient.Obvious wear loss initiates at 700 ℃.When sliding against GCr15-bearing steel,the cemented carbide experiences pronounced wear,with both the friction coefficient and wear rate progressively increasing with temperature,with wear rates of 2.17×10-8 and 6.81×10-8 mm3/(N·m)at room temperature and 700 ℃,respectively.The wear mechanism is dominated by abrasive wear.With increasing temperature,the abrasive wear intensifies,and oxidative wear occurs.关键词
