improved ways of surface profile measurements

3-D surface profile rendering can be an improved alternative for the classical tape based Testex. With this tape based approach, a visual comparator or spring micrometer is required. Surface profile is probably the most critical part of a coating system, it determines for a large part the adhesive bond between the surface and the coating. […]

What is a mill scale and do I have to remove it before coating?

Mill scale is iron oxide that forms on a surface during hot rolling of steel. During rolling, the high temperature involved causes oxide to form over the entire surface, which only increases in quantity as the rolling process progresses. The spots are often hard, but at the same time very brittle. The combination of the […]
