“…11,12 Extensive research has been pursued to increase the biomechanical properties of prostheses for articular replacement, one solution for this problem was to coat harder materials on the articulating surfaces to improve wear resistance and reduce the generation of wear particles generated. [13][14][15] Amorphous carbon (a-C) coatings such as the diamond-like carbon (DLC) is a coating produced by chemical/ physical vapor deposition 16,17 that has a low coefficient of friction, increased hardness, low wear rate and excellent biocompatibility. 18,19 Increased wear resistance leads to the reduction in the amount of debris, 20 allowing an increase in prostheses lifetime.…”

“…Among these, The OCP and potentiodynamic polarization curves are used to evaluate the electrochemical activity of the films. The OCP is considered as the potential of a galvanic coupling of the substrate and the film materials relative to the reference electrode . Figure shows the OCP curves of the DLC‐coating stainless steel sheets immersed in 3.5 wt% NaCl aqueous solution.…”

“…They observed a catastrophic failure when the films were subjected to wear–corrosion conditions because of poor adhesion between film and substrate. A multilayer architecture removes through‐film flaws resulting from the substrate surface or the coating process, which can impede the penetration of electrolyte . Moreover, the multilayer architecture improves toughness of the DLC films because cross‐sectional cracks can be terminated by their deflection at interfaces or braking in ductile layers during rubbing .…”

Super‐thick diamond‐like carbon (DLC) film is a potential protective coating in corrosive environments. In the present work, three kinds of DLC films whose thickness and modulation periods are 4 µm and 3, 21 µm and 17 and 21 µm and 7, respectively, were fabricated on stainless steel. The effect of different thickness and modulation periods on corrosion and tribocorrosion behaviour of the DLC‐coating stainless steel was investigated in 3.5 wt% NaCl aqueous solution by a ball‐on‐flat tribometer equipped with a three‐electrode electrochemical cell. The DLC‐coating stainless steel served as a working electrode, and its OCP and potentiodynamic polarization were monitored before and during rubbing. The wear–corrosion mechanism of the DLC films was investigated by SEM. The results showed that the increasing thickness can prolong significantly lifetime of DLC films in NaCl aqueous solution. In particular, the modulation period has a significant impact on the tribocorrosion resistance of the DLC super‐thick films. The study suggested that the increasing thickness of compressive stress layer could suppress film damage by reducing crack propagation rate. Thus, the super‐thick DLC film with thickness of 21 µm and 7 periods presented the best tribocorrosion resistance among all studied films. Copyright © 2016 John Wiley & Sons, Ltd.

“…Apesar da extensa literatura sobre o aumento da adesividade, a caracterização desta propriedade se mantém principalmente qualitativa [10][11][12]. Entre diversos ensaios, a indentação Rockwell C, descrita na norma VDI3198, e os ensaios de riscamento são as maneiras mais comuns de se medir a adesividade de filmes de DLC [10][11][12][13][14]. No presente estudo, ao invés de comparar aspectos morfológicos das indentações com padrões estabelecidos pela norma VDI3198, foi realizada uma comparação numérica através da quantificação da área desplacada através da análise de imagens produzidas por microscopia ótica.…”

ResumoA adesão de revestimentos multifuncionais em substratos moles é de extrema importância para o comportamento tribológico desta importante classe de tratamentos superficiais. Mais especificamente, testes de indentação e de riscamento são bastante utilizados na medição desta propriedade. No presente estudo, a adesão de filmes de DLC do tipo a-C:H depositados em aço baixo carbono nitretado foi investigada através de testes de indentação e riscamento. Os revestimentos foram produzidos através de PECVD em substratos de aço 1020 com dois acabamentos superficiais: lixado (Sq = 0,184 µm) e polido (Sq = 0,002 µm). Foram realizados testes de indentação Rockwell C e a adesão foi quantificada através da medição da área desplacada em imagens obtidas através de microscopia ótica. Esta análise produziu resultados semi-quantitativos, eliminando a análise qualitativa subjetiva sugerida pela norma VDI3198. Ainda, testes de riscamento foram realizados nas mesmas amostras com o mesmo indentador para que uma comparação entre ambas as técnicas pudesse ser estabelecida. Por fim, o método apresentado mostrou resultados coerentes, onde amostras com menor carga crítica apresentaram uma maior área desplacada. Amostras lixadas apresentaram um desempenho inferior em relação a adesividade. Palavras-chave: Diamond-like carbon; Adesão; Topografia; Aço nitretado. ASSESSMENT OF MULTIFUNCTIONAL COATING ADHESION: COMPARISON BETWEEN INDENTATION AND SCRATCH TESTS AbstractThe adhesion of multifunctional coatings on soft substrates is of paramount importance in the tribological behavior of this important class of surface treatment. In particular, scratch and indentation tests have been extensively used in order to assess this property. In this paper, the adhesion of a-C:H diamond-like carbon films deposited on nitrided low carbon steel was evaluated by indentation and scratch tests. The coatings were produced by PECVD onto 1020 steel substrates with two different surface finishing: ground (Sq = 0.184 µm) and polished (Sq = 0.002 µm). Indentation tests using a Rockwell diamond indenter were conducted and the adhesion evaluated by measuring the spalling region on images obtained by using optical microscopy. The analysis of the spalling regions produced semi-quantitative results, eliminating the subjective qualitative analysis proposed by the standard method VDI 3198. In addition, scratch tests were performed using the same indenter and a comparison between the two techniques was established. Finally, the method presented coherent results, where films with higher critical loads presented lower spalled areas. Ground samples presented an overall poorer adhesion performance.
