Destructive Film Thickness Measurement
Create a V-shaped cut through the coating down to the substrate and measure width of a’ (b’), which is proportional to the thickness a (b).
The specially designed blades which are attached to the instrument are used to make a short incision in the film. Then, the depth of the layer is measured with the built-in 50 fold microscope and the film is inspected for flaws.
Each of the cutting tips has two bevels which are made to precision with the mentioned slopes (see table). Since the slope of the cut is known, the measurement of the horizontal distance across this full slope (from the substrate to the top edge of the cut) is also a measurement of true vertical depth.
Buchholz Indentation Hardness
Place the byko-cut universal equipped with tool (Cat. No. 3427) and slip-on weight (Cat. No. 3434) on measuring position in accordance with standard. After 30 seconds measure indentation length using the built-in microscope.
