在微/细观（介于宏观和微观之间）尺度金属成形中，材料与工具之间的摩擦对材料变形的贡献比宏观尺度金属成形中的大。成形过程中的摩擦力很大程度上取决于粘附过程。通过测量注射镦粗行程后工具表面的接触电位差分布，研究了该工艺。通过测量，量化了材料的退火温度和成形速度对粘附量的影响。
In micro/meso (between macro and micro)-scale metal forming, the contribution of friction between the material and tool on the material deformation is higher than that in macro-scale metal forming. The friction during forming strongly depends on the adhesion process. The process was studied by measuring the contact potential difference distribution of the tool surface after an injection upsetting stroke. The effect of the annealing temperature of materials and the forming speed on the amount of adhesion was quantified by the measurements.
