What is plating thickness?

In the metal finishing industry, the thickness of a coating can dictate the functionality, appearance and cost of a final product. Coating thicknesses are typically found in the range from 0.

How is coating thickness measured?

Magnetic film gages are used to nondestructively measure the thickness of a nonmagnetic coating on ferrous substrates. Most coatings on steel and iron are measured this way. Magnetic gages use one of two principles of operation: magnetic pull-off or magnetic/electromagnetic induction.

How is film thickness calculated?

  1. The thickness of a single-layer film can be measured easily using a spectrophotometer. ...
  2. If film-thickness measurement software, which is sold as an option,is used, simply setting the wavelength range used for calculation and the refractive index makes it easy to calculate the film thickness, as shown in Fig.

How is zinc coating thickness measured?

There are two methods for measuring the zinc coating thickness of hot-dip galvanized steel; a magnetic thickness gauge and optical microscopy. The simplest and non-destructive way is to utilize a magnetic thickness gauge, as optical microscopy is a destructive test only used to resolve measurement disputes.
