1）不同種類Mg2B2O5晶須的加入使得復合材料的摩擦磨損性能略有不同，在相同條件下，基體、裸晶須、涂覆CuO和ZnO涂層增強的鋁復合材料的磨損率依次減小。 2) 在干摩擦條件下，隨著載荷與滑動速度的增加，復合材料的摩擦系數(shù)有變小的趨勢，磨損率隨之增大，且摩擦磨損機制由低載低速時的粘著磨損逐漸向高速高載下得磨粒磨損轉(zhuǎn)變，在摩擦磨損過程中伴隨著微觀疲勞磨損，三種磨損同時發(fā)生，互相交替變化。 3）通過SEM分析復合材料磨損表面、磨屑以及摩擦副表面形貌發(fā)現(xiàn)，隨著載荷與摩擦速率的增大，磨損表面出現(xiàn)大量的犁溝、裂紋和空穴且磨面上出現(xiàn)典型的機械混合層；磨屑由細小的顆粒狀逐步變?yōu)榇执蟮钠瑺钋夷デ蛏险持锏拿娣e有變小的趨勢。 萬分緊急�。。�！跪求給位大俠幫忙，汗顏！ |

1 Friction and wear properties of composite materials appearred slightly different with the accession of different types Mg2B2O5 whisker. under the same condition, the wear rate of substrate, bare whiskers , aluminum composite material coated with CuO and ZnO successively reduced. 2 Under dry friction condition,with the load and sliding speed increases, Friction coefficient of composite materials tend to be smaller, wear rate will be increased, Friction and wear mechanism gradually changed from adhesive wear in low-load and low speed to abrasive wear in high-speed and high load, associated with micro-fatigue wear in friction and wear process, three kinds of wear occurred simultaneously, alternating with each other. 3 Analyzed the worn surface of composite materials、 wear debris and morphology of friction surface by SEM, found that with the increasing rate of load and friction, it appears a large number of furrows, cracks and holes on wear surface , and typical mechanical mixed layer on the grinding surface. Wear debris gradually changed from small granular to thick sheet, adhesive material on the area tend to be smaller. |
