Robust solution for the evaluation of stratified functional surfaces

In the 1990s ISO published a set of empirical specifications for micro-nano surface manufacture, however, how to characterize stratified functional surfaces is still in debate. The structure of these specifications had not been designed for consistency and stability, which has led to many different instrumental software having seriously divergent parametric results. This paper aims to present a robust solution for the assessment of surfaces with stratified functional properties. It intends not only to provide unambiguous specifications and deterministic numeric algorithms, but also to demonstrate illustrative evaluation examples derived from stratified functional surfaces.
