摘要
采用平板滑动实验研究了表面相组成、表面粗糙度、拉速、压力及涂油品种等因素对汽车用合金化热镀锌IF钢表面摩擦系数的影响。研究发现对于合金化热镀锌IF钢表面存在大量柱状ζ相的镀层表面,其表面摩擦系数通常大于以粒状δ1相为主的镀层表面;以柱状ζ相为主的镀层表面,当镀层表面存在大量尺寸较大的“火山口”状形貌时,其表面摩擦系数相对较小。
The effect of surface phase constitution, surface roughness, sliding speed, press force and anti- rust oil on friction coefficient of galvannealed IF sheet steel has been tested and researched. It was found that while there were a lot of columnar ζ phase in surface for the sheet steel, the friction coefficient usually higher that surface coating mainly containing granular δ_1 phase; as there were a lot of larger scale 'crater' morphology in surface coating mainly containing columnar ζ phase, the friction coefficient was relatively lower.
