Abstract: In order to study the influence of laser texturing on the performance of a drawing surface,the characteristics of friction behavior and the morphology of laser texturing on the die surface were analyzed.In the view of asperity contacts of laser texturing morphology,the friction coefficient on the laser texturing surface was composed of dry friction and lubrication friction, and the relation model between the friction coefficient and the surface morphology parameters was established,the effect of laser texturing morphology on the surface coefficient of friction was discussed.At last a large number of tribology experiments on laser texturing surface were taken to verify the accuracy of the model.The result shows that laser texturing improved tribology character, and the model provides a theoretical base for further research of laser texturing on drawing mould.
