摘要：
The influence of overblasting on surface properties of low-carbon steel was investigated. In detail, surface roughness, contact angle, Vickers-hardness, degree of surface contamination, and pull-off strength were evaluated. It was shown that overblasting had notable effects on the surface properties. Most importantly, the surface roughness was significantly reduced, and the microhardness of the substrate increased. Also, overblasting increased surface wettability. The influence on the pull-off strength of applied coating systems was only marginal.
