“…The tests were carried out in dry sliding 39 in three different conditions for the evaluation of AISI M35 steel with and without DLC, as shown in Table 2, whose objective was to verify the friction behavior under load influences normal 8 and the peripheral sliding speed. In each test, 6 mm diameter spherical bodies 40 made of AISI 52100 steel (0.98% C and 1.40% Cr, 63 HRC) 8 were used. Then, the wear tracks were analyzed in the SEM and the friction coefficient curves were plotted through the acquisition of data from the RS232 interface coupled to the tribometer.…”

“…DLC has received notable prominence when applied as a coating for several components used, for example, mechanical components of internal combustion engines, anti-reflective surfaces for solar cells or optical elements, protective coatings on biomedical implants, prostheses and magnetic disks [4][5][6][7] . This diversity of application is due, in general, to the properties of wear resistance, low friction coefficient, corrosion resistance and chemical inertness 8 , in addition to its manufacturing process being considered less aggressive to the environment 2 . A greater emphasis has been placed on all the strategic optimization applications that can assist the advancement of industries in the face of the current challenges of combining quality, quantity, time, cost and environmental impacts 9,10 .…”

“…The influence of the deposition parameters of the HiPIMS process (High Power Impulse Magnetron Sputtering) on the chemical composition, structure, mechanical and tribological properties of the DLC was studied 8 . Different films were deposited on samples (discs) of SKH51 steel (HRC 65), which were tested on a ball-on-disc tribometer.…”

“…A Figura 4 mostra o espectrograma obtido. Os resultados obtidos na análise por XPS demonstraram a presença de picos sp 2 C-C em 284,3 (+-0,3), sp 3 C-C em 285,4 (+-0,3), C-O em 287,0 (+-0,3) e C=O em 288,5 (+-0,3) eV, valores semelhantes aos encontrados em outros trabalhos (KIMURA et al, 2016;KAO et al, 2019). Dessa forma, pode-se afirmar que o revestimento DLC analisado é composto pelos elementos carbono e oxigênio, com uma prevalência de carbono, que corresponde a mais de 92% do material.…”

A utilização de revestimentos finos é uma alternativa muito utilizada para se alterar características superficiais. No caso de ferramentas de corte, o objetivo é de se proporcionar melhorias ao processo de usinagem como, por exemplo, melhor acabamento superficial dos produtos e aumento da vida útil das ferramentas. O DLC – Diamond-like Carbon é um material amplamente utilizado como revestimento. Ele corresponde a uma forma metaestável do carbono amorfo, na qual são encontradas ligações sp3 e sp2, próprias do diamante e do grafite, respectivamente. Por ser constituído por esse misto de ligações, o DLC é capaz de combinar características presentes em ambos os materiais, como boa resistência ao desgaste e baixo coeficiente de atrito. O presente estudo teve por objetivo realizar uma comparação entre o desempenho de amostras de aço rápido AISI M-35 revestidas por DLC e amostras não revestidas, no que se refere à resistência ao desgaste por microabrasão. Primeiramente, foi realizada a caracterização dos materiais. O filme DLC foi analisado por meio das técnicas de espectroscopia Raman e espectroscopia de fotoelétrons excitados por raios-X. Sua análise permitiu caracterizá-lo como um carbono amorfo não tetraédrico de espessura média de cerca de 1,5 μm. O aço AISI M-35, por sua vez, teve sua composição química determinada por espectrometria de emissão ótica. Por fim, foi analisado o desempenho das amostras revestidas e não revestidas no teste de resistência à microabrasão, o caloteste. As calotas obtidas tiveram o diâmetro, em média, 71% menor nas amostras que receberam o revestimento. O coeficiente de desgaste específico foi, em média, 142 vezes maior no aço não revestido por DLC. Esses resultados permitiram concluir que a utilização do DLC como revestimento em ferramentas de corte fabricadas em aço AISI M-35, pode se constituir como uma alternativa viável quando se busca melhorar o desempenho de ferramentas de corte.

“…However, there are some shortcomings such as high intrinsic stress, poor adhesion strength between the film and substrate, and unstable tribological properties, which limit their further development [9][10][11][12][13]. Most of the previous studies in recent years investigated the effect of deposition temperature [14], sputtering power [15,16], deposition pressure [16], and substrate material [17] on the tribological behavior of hydrogen-free diamond-like carbon coating. Few studies [2,18] have been found on the relationship between film thickness and tribological properties of DLC coatings, and the tribological properties of ultra-thick (more than 1 µm) DLC coating deposited by HiPIMS technique remain unclear.…”

Effect of Thickness on Tribological Behavior of Hydrogen Free Diamond-like Carbon Coating

The effects of film thickness on the tribological behavior have been investigated for hydrogen-free diamond-like carbon coating in this paper. The film was deposited on cemented carbide substrate (YG10C) by applying a high power impulse magnetron sputtering (HiPIMS) technique. The reciprocating ball on the disc test was conducted on the film with different thicknesses from 0.66~1.26 μm against the ZrO2 ball. The friction coefficient and wear resistance of the coating with different thickness showed a unimodal change. Numerous defects were observed on the surface of the film with a thickness of 0.66 μm and the wear mechanism was mainly plow-grinding. Therefore, the steady-state friction coefficient reached the maximum value of 0.22. The coating with a thickness of 1.01 μm had a higher sp3 content and a smoother, dense surface. A graphite transfer layer with low shear strength was detected on the ZrO2 ball against the film with a thickness of 1.01 μm, which led to the reduction in friction, thus the steady-state friction coefficient reached the minimum value of 0.10. However, the internal stress of the film increased with increasing thickness due to the distortion of the bond angle of internal structure when the film was bombarded by high-energy particles. The peeling coating was observed under reciprocating sliding, which both played the role of plowing and boundary lubrication film. The steady-state friction coefficient was 0.14 with a coating thickness of 1.26 μm. As a result, the hydrogen-free diamond-like carbon coating with optimized thickness shows a smooth and compact surface, low internal stress, high sp3 content, and better tribological properties.
