氟金云母玻璃陶瓷摩擦磨损性能研究

Friction and Wear Behavior of Fluorophlogopite Glass Ceramics

在MPX-2000型摩擦磨损试验机上考察了不同载荷下氟金云母玻璃陶瓷与碳钢对摩时的摩擦磨损性能,用金相显微镜观察和分析磨损表面形貌,测试了摩擦系数和玻璃陶瓷的磨损率,并探讨了材料的磨损机理。结果表明,随着载荷的增加,摩擦副的摩擦系数明显增大,有较大波动。

The friction and wear properties of wear-resistant fluorophlogopite glass ceramics sliding against carbon steel at various loads and sliding velocities were evaluated on an MPX-2000 ring-on-pin friction and wear tester.The morphologies of the worn surfaces of the glass-ceramics were observed on an optical microscope,friction coefficient and wear rate of glass-ceramics were tested.As the results,the friction coefficient of the glass-ceramics was greatly dependent on the applied load.As wear load increased,the friction coefficients increases significantly.The wear rate between glass ceramics and bearing steel increased when the applied load increased.Abrasive wear is the main wear form between glass ceramics and carbon steel materials.
