摘要
通过测试Al2O3基陶瓷材料、Si3N4基陶瓷材料及硬质合金材料等刀具材料与木质复合材料摩擦系数及磨损前后的粗糙度变化,分析了几种刀具材料与木质复合材料的摩擦特性。研究结果表明,陶瓷刀具材料与MDF、PB的摩擦性能要明显优于硬质合金刀具材料,且Si3N4基陶瓷材料优于Al2O3基陶瓷材料的摩擦性能;硬质合金材料与木粉/PE复合材料摩擦性能较陶瓷材料稳定;添加ZrO2的Al2O3基陶瓷材料摩擦性能优于未添加ZrO2的Al2O3基陶瓷材料;刀具材料种类对MDF摩擦系数的影响显著,而对PB摩擦系数的影响并不显著;正压力对摩擦力的影响不十分明显;添加ZrO2的Al2O3基陶瓷材料可以抑制腐蚀磨损。
An experiment was conducted to study the tribological properties of ceramic cutting tool materials and wood-based ma- terlals by examining how Al2O3 ceramics and Si3 N4 ceramics behave in dry sliding when in contact with wood-based materi- als and compared their behavior with that of tungsten carbide material. Results show that the ceramics exhibit much better tribological characteristics than tungsten carbide material, and Si3N4 ceramics exhibit better than Al2O3 ceramics. The Al203 ceramics with an addition of ZrO2 have better frictional performance than the common Al203 ceramics in frictional contact with wood-based materials. The tungsten carbide has better frictional performance than ceramics in frictional con- tact with wood flour/PE material. There is a well-marked difference in friction coefficient between various cutting materi- als/MDF frictional pair, but the differences between various cutting tool materials/PB frictional pair are insignificant. An increase in normal force didn＇ t result in any significant decrease of friction coefficient. An addition of ZrO2 in Al2 03-ce- ramics could inhibit corrosive wear.
