Electroplating surface tension
WebSep 1, 2024 · As the EN bath is plating it evolves a voluminous amount of hydrogen gas. If the solution’s surface tension is considerably high or simply not low enough, the interfacial tension at the surface of the plating object will be high and therefore the ease with which the hydrogen bubbles that generate is removed from the object is lessened.

WebWhat is the revised surface tension limit for decorative chromium electroplating tanks when measuring surface tension with a tensiometer? The amended Chrome NESHAP has added a separate surface tension limit of 35 dynes/cm when using a tensiometer. The surface tension limit of 45 dynes/cm still applies when using a stalagmometer. In surface science, a tensiometer is a measuring instrument used to measure the surface tension (γ) of liquids or surfaces. Tensiometers are used in research and development laboratories to determine the surface tension of liquids like coatings, lacquers or adhesives. A further application field of tensiometers is the monitoring of industrial production processes like parts cleaning or electroplating.
