摘 要: 采用自制的微动磨损试验机，开展了690合金管/405不锈钢的切向微动磨损试验，研究了位移幅值(15、30、
80和200 μm)对其微动磨损特性的影响. 试验结果表明：当位移幅值改变时，微动运行状态会发生改变. 当位移幅值
为15 μm时，微动状态为部分滑移区，此时摩擦系数最小，磨损率最低，微动损伤最轻微；当位移幅值为30 μm时，微
动运行于混合区，摩擦系数明显高于部分滑移区；而当位移幅值为80和200 μm时，微动运行于完全滑移区，稳定阶
段的摩擦系数与混合区的接近. 总体而言，随着位移幅值的增大，磨痕宽度增大，磨损加剧，磨损体积增加. 部分滑
移区的磨损机制主要为黏着磨损和剥层，混合区主要的磨损机制为剥层，而完全滑移区的磨损机制主要为剥层磨
损和磨粒磨损.

Abstract: The tangential fretting wear tests of 690 alloy tube/405 stainless steel were carried by a self-designed fretting
wear test rig. The effect of displacement (15 μm, 30 μm, 80 μm, 200 μm) on fretting wear characteristics has been
investigated. With the increase of amplitude, fretting wear tests were running in partial slip regime (15 μm), mixed slip
regime (30 μm) and gross slip regime (80 μm and 200 μm), respectively. The friction coefficient of partial slip regime
was lower associated with slight damage, while the friction coefficient of mixed slip regime and gross slip regime were
relatively higher. Additionally, the steady values of mixed slip regime and gross slip regime were almost same.
Generally, with the increasing displacement, the width of wear scar and wear volume increased. The main wear
mechanisms of partial slip regime were adhesion wear and delamination, while the main wear mechanisms of mixed slip
regime was delamination. And the main wear mechanisms of gross slip regime were delamination and abrasive wear.
Key words: 690 alloy tube; fretting wear; displacement; friction coefficient; wear mechanism
