Resumo

The aim of this research work is to study the inter-relationship, under controlled industrial conditions, between surface topography (characterized by 2D and 3D) roughness parameters and painting surface finish quality for automotive steel sheet stampings. Different surface textures obtained from cold rolling finishing have been evaluated in terms of paintability tests (rating and spectral curve) and tentatively related to the roughness (2D and 3D) obtained from the cold finished sheets. Some relevant tendencies have been established amongst these parameters. The results here presented are in accordance with other recently published research show that there is a clear relationship between these parameters, and that further detailed studies are needed.
