THE EVALUATION OF THE PRACTICAL ADHESION STRENGTH OF BIOCOMPATIBLE THIN FILMS BY FUZZY LOGIC EXPERT SYSTEM AND INTERNATIONAL STANDARDS

Vladimír Socha – Patrik Kutílek – Slávka Vitečková

   This work focuses on describing an evaluation method used in nano- and micro-thin films based on fuzzy logic expert systems. The aim is the elimination of comparison complications with mechanical properties of tin films, practical adhesion being one of the most important characteristic of tin films. The basic method for evaluating the practical adhesion strength is scratch test method, while the issue is that research teams use measurement methods based on the non-uniform measurement conditions of adhesion of biocompatible thin films. The authors tested new evaluation method and procedure based on international standards and fuzzy rule based expert system in order to eliminate the problem of comparison of practical adhesion of the films. The article concentrates on testing and using the fuzzy logic expert system designed based on international standards for evaluating adhesion of thin films in nano and micro dimensions. The materials used for tests of the fuzzy expert system were DLC biocompatible layers and substrate a titanium alloy Ti6Al4V.

Keywords: international standards, fuzzy expert system, practical adhesion , scratch test, thin film
