Abstract
A method of testing light metal parts, in particular aluminum components, which have been coated by anodizing, in particular by TSA anodizing, to determine whether they have been coated is described. According to the invention, the surface resistance of the surface of the component is measured and the surface coating of the component is classed as good when the surface resistance is higher than a prescribed high resistance value.
Claims16
A method of testing coated light metal parts, to determine whether they have been coated, comprising the steps:
- providing a coating on a surface of the light metal part by anodising;
- measuring surface resistance of the surface of the light metal part;
- classifying the surface coating of the surface of the light metal part as good when the measured surface resistance is higher than a prescribed high resistance value, wherein the surface resistance is measured by detachable electrodes placed on the surface of the light metal part and wherein correct coupling of the detachable electrodes to the light metal part is verified.
