摘　　要：本文通过高压透射电子显微镜,对国外钢领和国产钢领的金属薄膜,进行了微观亚结构和相成分的电子显微对比分析,并结合HOLM和BURWELL的磨损方程和钢领的疲劳极限以及裂纹扩展门槛值ΔKth,在钢领的前期抗粘着磨损和后期抗疲劳磨损中的作用机理作了较全面的论述。This paper described use of high voltage transmission electron mi croscopes to observe mctallic films of both home-made and imported spinning rings. A comparable electron microstruetural analysis was carried out on microsubstructurcs and phase compositions, this paper gave detailed presentations on the functions and mechanisms in the course of early stage anti-adhesion erosion and late stage anti-fatigue erosion of the spinning rings by using combination of HOLM and BURWELL erosion formula as well as fatigue limit and fracture expansion threshold value △Kth of the spinning rings.
