“…[1][2][3] Various synthesis methods have been studied for fabricating carbon films to date, such as ion beam assisted deposition (IBAD), 4) laser deposition 5) and plasma enhanced chemical vapor deposition (PECVD). 6) However, since the mechanical properties of the films are different from that of the substrate, hard layers of diamondlike materials deposited directly on the metallic substrate result in a high residual stress at the fracture.…”

DLC multilayer films were deposited on an AISI 304 stainless steel substrate by the composite technique of unbalanced magnetron sputtering and plasma immersion ion implantation (PIII). Structure characterization was performed on the films by Raman spectroscopy (RS) and Glancing X-ray Diffraction (GXRD). Composition analysis of the surface layer on the implanted substrates was carried out using auger electron spectroscopy (AES). The mechanical properties of the films were evaluated by nanoindentation. The results showed that the Raman spectra were divided into a "D" disordered peak and a "G" graphite peak with the integrated intensity ratio between them (I D /I G ) being 1.30. The implanted carbon penetrated the substrate resulting in complete interfacial mixing. The hardness, elastic modulus, fracture toughness and interfacial fracture toughness of the films were about 19.84 GPa, 190.03 GPa, 3.75 MPa·m 1/2 and 5.68 MPa·m 1/2 respectively. Compared with that of a DLC coating deposited directly by the PIII technique, the interfacial fracture toughness of the multilayer films increased, which is mainly attributed to the interfacial mixing at the interface.

“…1. Basic idea behind a fuzzy system is to interpret an input, and based on sets of if-then rules, obtain an output or due to the application of nonstandard conditions [5,[20][21][22][23][24][25]. One option in the recent situation is the use of the standards with the addition of prescribed measurement procedures and conditions.…”

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.
