CBE+ Laboratories specialise in the process of micro-section testing, enabling us to provide our customers with certification to meet the required regulatory standards.
A coating or plating application is commonly used for the protection of the substrate, therefore the thickness of the deposited layer is an important factor with regard to the overall performance of the coating or plating.
In order to carry out a micro-section test, a shim of identical material is plated alongside a customer’s component, using the same method. The plated shim is then cut up using a diamond bladed cutting tool to minimise vibration and assure accuracy.
The resulting sample is then set in clear resin, and polished to a fine finish. The surface of the sample is then etched in an appropriate chemical solution to allow the nickel or diffusion layer to be examined under the microscope.
A UKAS calibrated slide is then used to accurately calibrate software used to measure these layers, determining the thickness of the cross section under an optical microscope. This allows CBE+ Laboratories to definitively demonstrate and certify the relevant thickness requested on behalf of our customers.
The specification for micro-section testing is: BS EN ISO1463 & ASTM B487
