| 摘 要： | 1 IntroductionThe friction and wear behavior of metals underuni-directional sliding has been widely studied eitherby ball-on-disc or by block-on-ring test machines1].In practical applications, however, we will usuallymeet cross-sliding condition. For example, compositefretting wear of a ball on disc includes the tangentialfretting and the radial fretting 2] .Zhu et al3-4] stud-ied the composite fretting wear behaviors of GCr15bearing steel and 7075 aluminum alloys. In slidingbearing, the …

| Abstract: | Friction and wear of GCr15 under cross-sliding condition is tested on a ball-on-disc wear test machine. Thisresult shows that the cross-sliding of friction pair leads to different friction and wear behavior. For the condition de-scribed in this paper, the friction coefficients with ball reciprocating are smaller than that without ball reciprocating.The friction coefficients increase with the increase of reciprocating frequency.. The wear weight loss of the ball sub-jected reciprocating sliding decreases, however, the wear weight loss of disc against the reciprocating ball increases. Incross-sliding friction, the worn surfaces of the ball show crinkle appearance along the circumferential sliding traces.Delaminating of small strip debris is formed along the plowing traces on the disc worn surface. The plowing furrow onthe disc surfaces looks deeper and wider than that without reciprocating sliding. The size of wear particles fromcross-sliding wear is larger than those without reciprocating sliding. |
