Functional correlation surface texture / grip of a deposit : case of NiP

Abstract

This work studies a functional correlation between different texture parameters and the adherence of NiP coating on a metal substrate. Multiple surfaces with different milling feed rate and coated with NiP went through a pull-off adhesion test. This study determined through texture analysis functional correlation between characterization of surface topographies and the strength measured during the test. In order to study if a multi-scale approach improve the correlation, a “conventional” method based on ISO 25178 procedure and a multi-scale method based on wavelet filtering are compared.
