Abstract
In this work new grade 304L austenitic stainless steel has been blasted with four types of locally produced abrasives: garnet, aluminum oxide, steel grit and platinum grit, different in granulometry and nature leading to variation in the deformation of the surface. The different modification in the surface’s morphology was analyzed with the scanning electron microscope and characterized with conventional profiling equipment. A clear distinction could be made between the initial nanometer-scale surface texture of the stainless steel and the different surface topography obtained after abrasive blasting. The results obtained assisted in predicting and understanding the relationship between adhesion performance of a generic type of coating system and the changes in the surface morphology.
