为降低人类对于金属材料的依赖程度,研发一款可部分替代粉末冶金铜基轴承的新一代滑动轴承。以白杨剩余物粉末为基材、纳米刚玉粉为增强因子,以模压试件的压溃强度、摩擦系数、磨耗量为响应指标。借助响应面试验法进行试验设计与分析,研究模压成形温度、增强因子和成形压力对试件成形工艺的影响,并对试件的制备工艺参数进行优化,同时建立了试件摩擦系数的数学模型。试验结果表明,当白杨粉末粒度60目、成形温度160℃、纳米刚玉粉含量6%时成形工艺条件为最佳组合,据此制备的颗粒增强木质滑动轴承的摩擦系数为0.083,磨耗量为0.0028g/100r,压溃强度为129.78MPa。试验结果表明:颗粒增强木质滑动轴承在...

The purpose of this research is to develop a new generation of sliding bearing which can replace the powder metallurgy copper base bearing in some fields,in order to reducing the dependence of human on metal materials. Take the remaining powder of poplar powder as substrate,nanometer corundum powder as reinforcement factor, and take the crushing strength, friction coefficient and wear rate of the molded specimens as the response index. With the aid of response surface design, the experiment design and analysis were carried out to study the effect of forming temperature, enhancement factor and ...
