client needs
Substrate: steel (magnetic steel); coating: electroplated nickel. Requirements: Measure the thickness of the nickel layer, the nickel layer is relatively thick, generally about ten mm.
Doubt: Know if Elcometer 456 A456CFBI2 can test this coating Thickness Gauge?
engineer suggestion
1. It is confirmed that the customer is a magnetic steel part. In view of the base material of magnetic steel parts, the nickel layer is a non-magnetic coating, so a thickness measuring instrument based on the principle of magnetic induction thickness measurement can be used.
2. The customer's nickel plating layer is relatively thick, reaching more than ten mm, so it is necessary to choose a large-range Thickness Gauge. The thickness measurement range of Elcometer 456 A456CFBI2 model is 0~5000 microns, which does not meet the customer's needs.
The engineer suggested Elcometer 456 A456CFNFBS Dual-purpose Coating Thickness Gauge , with a thickness measuring range of 0~30mm, which can be used not only to test the thickness of nickel layer, but also to measure cadmium, chromium, nickel, and paint layers.
