摘要

本文所述研究的目的是分析片材变形引起的主要表面参数值和摩擦系数值的演变。在干燥和润滑两种条件下，采用拉延试验研究了深冲优质钢板的摩擦性能。在0至0.28之间的真实应变范围内，片材的塑性变形的增加导致振幅粗糙度参数Ra、Rp、Rt的值的增加，该值沿着片材的轧制方向并且垂直于该方向测量。变形薄板摩擦现象的特征是由预应变和应变硬化现象形成的薄板方向形貌的复杂函数。研究还发现，由于应变硬化现象，板材的显微硬度随着板材变形而增加。然而，这种关系几乎是线性的。

Variation of surface roughness, micro-hardness and friction behaviour during sheet-metal forming

The aim of the research described in this paper is to analyse the evolution of the main surface parameters values and friction coefficient value due to the sheet deformation. Frictional properties of the deep-drawing quality steel sheets were investigated using the strip drawing test under both dry and lubricated conditions. An increase in the plastic deformation of sheets in the range of true strain between 0 to 0.28 caused an increase in the value of amplitude roughness parameters Ra, Rp, Rt, measured along the rolling direction of the sheet metal and perpendicular to this direction. The character of frictional phenomena of the deformed sheets is a complex function of sheet directional topography, formed by pre-straining and strain-hardening phenomena. It was also found that owing to the strain-hardening phenomenon the micro-hardness of the sheet increased with the sheet deformation. However, this relation was near linear.
