Abstract

In this paper,the influence of surface roughness difference of cold rolled plate on the subsequent coating process is explored.In the process of the experiment,the roughness and micro-morphology of the cold-rolled sheet and the coating effect of the pre-treatment and electrophoresis was verifled by investigation of various items such as the thickness of the sample film,the mechanical properties of electrophoresis and the corrosion resistance.

Key words

coating;roughness;thin film pre-treatment;salt spray test
