client needs
The surface of the product is non-magnetic, and the materials are iron, aluminum and copper. The process is to galvanize the surface of the part, the thickness of the zinc layer, and a layer of lubricating protective layer after galvanizing, and measure the thickness of the protective layer. The thickness of the zinc layer is 5 microns, and the thickness of the surface treatment protective layer is 2-3 microns, which are separately identified and calculated.
engineer suggestion
It is recommended to use PosiTector 6000 FNDS series models for the thickness measurement of galvanized layer and galvanized top coating. The FNDS probe can measure the thickness of paint and zinc layer in the composite coating system at the same time, and display it with one reading. The galvanized coating system can measure the thickness of the galvanized layer and the door coating separately through this sensor, and it can automatically identify and measure whether the substrate is non-ferrous metal or black metal.
The sample diagram of the instrument measurement is as follows:
