How is plating thickness measured?

How is plating thickness measured?

The plating thickness is determined by the amount of magnetic flux that the probe passes through the non-ferromagnetic plating and flows into the ferromagnetic metal substrate.

How is coating thickness calculated?

For example, if a coating were 45% solids by volume, its theoretical coverage would be 1604 X 0.45 or 722 square feet at 1 mil dry film thickness. If a specification called for a dry film thickness of 2 mils, the theoretical coverage would then be 722 square feet divided by 2 mils, or 361 square feet per gallon.

What is the thickness gauge?

A thickness gauge is a hand-held measuring device used to measure the thickness of a given materials or sample. They are frequently used in product manufacturing and engineering operations that require a specific object thickness in order to comply with governmental regulations.

What is DFT thickness?

Dry film thickness (DFT) is the thickness of a coating as measured above the substrate. This can consist of a single layer or multiple layers. DFT is measured for cured coatings (after the coating dries). Film thickness is measured to ensure its compliance with ASTM, ISO and other specifications.

What is a coating thickness gauge?

Coating thickness gauges (also referred to as a paint meter) are used to measure dry film thickness. The Elcometer range of dry film thickness gauges (DFT gauge), provide reliable and accurate coating thickness measurements on almost any metal substrate, whether ferrous or non-ferrous.

What is the difference between WFT and DFT?

Dry film thickness, or DFT is a measurement of the dry and cured material after all liquid has evaporated. DFT = WFT x % volume solids. For a 67% volume solids material with a WFT of 18 mils, DFT = 18 x 0.67 = 12 DFT. By simply reversing the equation DFT can also be measured to determine what the applied WFT was.
