How to choose a film thickness gauge (coating thickness gauge)

发布时间:2018/7/16

1. Copper and chrome layer on plastic: It is recommended to use Coulometric thickness gauge (which will damage the coating) or X-ray thickness gauge (non-destructive measurement). For example, the copper layer can be considered eddy current thickness gauge at 10μm~200μm (lossless) measuring)
2, galvanized layer on the metal parts: If the steel substrate should be used economical magnetic induction method thickness gauge (non-destructive measurement). Other metal substrates with Coulomb thickness gauge (which will damage the coating) or X-ray thickness gauge (non-destructive measurement)
3, the electrophoretic paint on the iron substrate, the paint should use the economical magnetic induction method thickness gauge (non-destructive measurement). Electrophoretic paint on other metal substrates, the paint should use economical eddy current thickness gauge (non-destructive measurement)
4, chrome layer reference 1 item, 2 items
6, the interior and exterior parts of the paint can only be measured by the cutting method (PIG, will destroy the coating)) ultrasonic method (non-destructive measurement) can measure more than 10 microns coating, but sometimes not measured.
