CHARACTERIZATION OF PERFORMANCE COATINGS USING THE MULTI-CRITERIA ANALYSIS METHOD

Abstract

The paper presents a method for evaluating surface properties of various materials and coatings, based on multi criteria

analysis. Newly developed materials, have a complex surface topology due to the manufacturing processes enabling strict surface parameter control. Evaluating these materials is a costs and time consuming process. The main objective of the presented method is to offer a good characterization of the surface properties, based on basic laboratory measurements and to enable an effective comparison tool between two or more materials with similar properties. The method was developed by analyzing the basic surface parameters of three performance coatings. The measured surface values were transposed into specific parameters of the multi-criteria analysis method and a final comparison was done in order to determine the best material. In order to confirm the method, more complex investigations were done in parallel. The results of these investigations confirmed the results obtained by using the multi-criteria analysis method.
