以杨木粉末为基材、纳米刚玉粉为增强因子,采用温压成形技术制备纳米颗粒增强木质滑动轴承,研究了纳米刚玉粉含量对木质滑动轴承的摩擦系数、磨耗量和承载能力的影响规律,并对试件摩擦磨损表面微观形貌进行了表征。结果表明:纳米刚玉粉对木质滑动轴承的摩擦磨损性能具有明显的改善作用,当纳米刚玉粉含量为6%时效果最佳;含6%纳米刚玉粉的木质滑动轴承的磨合期短(~ 7 min)、摩擦系数小(~ 0.11)、极限PV值高(161.7 MPa·m·min~(-1)),可望在一定工况下替代烧结青铜用于轻纺机械。

Taking poplar powder as substrate, nano corundum powder as reinforcement factor, nano particle reinforced wooden sliding bearing was prepared by warm compaction technology. The influence of nano corundum powder content on the friction coefficient, wear capacity and bearing capacity of the wooden sliding bearing was studied, and the surface micro-morphology of the friction pair was characterized and analyzed. The results show that the effect of nano corundum powder on the friction and wear properties of wood sliding bearings is obviously improve...
