由于表面体积比的增加，微观粗糙度等物理参数在微成形过程中变得非常重要。摩擦尺寸效应是金属成形过程中非常重要的现象，由于传统的模型不可靠，因此越来越受到研究人员的关注。本文研究了考虑润滑剂作用的sus304不锈钢的微滚压变形特性，接触区存在粘滞区。分析了表面粗糙度和油膜厚度的演变规律。箔材厚度对轧制的摩擦学特性起着重要的作用。所有结果都在台式2-Hi微轧机上得到了实验验证。
Physical parameters such as microscopic roughness become very important in micro forming process due to increasing surface to volume ratio. As a very important phenomenon in metal forming process, friction size effects are becoming more attracting for researchers because traditional models are not reliable. In this study, the micro rolling deformation characterization has been investigated with SUS 304 stainless steel considering the effect of lubricant, and there exists a sticking area in the contact zone. The evolution of surface roughness and oil film thickness are analyzed. The foil thickness plays an important role in the tribological features of rolling. All the results have been verified experimentally via the desktop 2-Hi micro rolling mills.
