; microstructure; wear mechanism 1 Introduction Silver matrix self-lubricating composites, reinforced with graphite, have been used in many industrial applications, such as bearings, bushings as well... wear [23,24]. Compared with the shallow grooves, the delaminated regions and spalling pits were the main forms of wear for Ag-25FG. Therefore, the main wear mechanism of Ag-25FG was the delamination......

with the volume fraction of fly ash particles and the wear mechanism is characterized as abrasive wear and adhesive wear. On the other hand, the wear mechanisms in the composites are transformed with increasing load and fly ash volume, mainly it is delamination wear and abrasive wear. Key words: fly ash; aluminum matrix composite; friction and wear; wear mechanism 铝基复合材料由于具有较好的力学及耐磨性能,在航空航天和汽车工业上获得......
Friction and Wear Mechanism of Unlubricated 304L Austenitic Stainless Steel at Room Temperature陈国清School of Materials Science and Engineering,Dalian University of Technology摘 要:To explore wear mechanism of stainless steel used in nuclear pump,the wear properties and the worn surface characteristics of unlubricated 304L austenitic stainless steel......
conditions. Key words: self-lubricating composites; tribological behaviors; atmosphere; wear mechanism 1 Introduction Silver matrix composites containing solid lubricant are known as self-lubricating...-magnification SEM image of the worn surface (Fig. 6(b)) shows the presence of cracks generated by the spalling or delamination process. Delamination is a fatigue-related wear mechanism and is created......
with liquid pitch and resin, and their friction and wear properties under braking pressure of 0.6MPa and worn mechanism were studied. The results show that C/C composites by resin impregnation after..., C/C composites by pitch impregnation only have the highest dimension wear rates due to the largely fracture of fibers and the wear mechanism are mainly abrasion wear and oxidation wear. Key words: C......
Sliding wear behaviors of electrodeposited Ni composite coatings containing micrometer and nanometer Cr particles ZHAO Guo-gang(赵国刚), ZHOU Yue-bo(周月波), ZHANG Hai-jun(张海军) College... nm. The friction and the wear performance of the co-deposited Ni-Cr composite coatings were comparatively evaluated by sliding against Si3N4 ceramic balls under non-lubricated conditions. It is found......
with the largest graphite particle size has the best wear resistance. The wear mechanism of all the composites at low load is abrasive wear and oxidation wear; at high load, except the composites with the particle size of 240 μm whose wear mechanism is still abrasive wear and oxidation wear, the wear mechanism of others changes to dellamination wear. Key words: magnesium matrix composite; particle size......
