Hardness and surface roughness of hydrogenated amorphous carbon films synthesized by atmospheric pressure plasma enhanced CVD method with various pulse frequencies

Synergetic effects of surface texturing and solid lubricants to tailor friction and wear – A review

“…A few other approaches do not fit the classification as direct and indirect texturing, but rather refer to simultaneous texturing during coating deposition, such as the deposition of DLC through a mask, thus producing a textured coating [225]. Another example is the production of textured DLC using atmospheric pressure plasma enhanced chemical vapor deposition that naturally forms a stochastic texture composed of nanopillars during deposition [226].…”

Growth process of hydrogenated amorphous carbon films synthesized by atmospheric pressure plasma enhanced CVD using nitrogen and helium as a dilution gas

“…Therefore, one cycle of deposition process is completed within one pulse and interval. 22,25) 3.2 Synthesis from C 2 H 2 /N 2 Figure 4 shows the surface SEM images of the films synthesized from C 2 H 2 =N 2 at various pulse frequencies and Fig. 5 the shows cross-sectional SEM image of a-C:H films synthesized at 10 kHz with changing film's thickness.…”

“…21) We, therefore, controlled the growth of the particles on the a-C:H film synthesized from C 2 H 2 =N 2 by exploiting the effect of the pulse frequency of the power source. 22) In this study, we investigated the growth process of the particles of a-C:H film as it is related to the thickness of the film. For this, we used two different dilution gases (i.e., N 2 and He) at different pulse frequencies.…”

Polymer Surface Modifications by Coating

“…These photo-grafting polymerization methods are applicable to various kinds of polymer materials for substrates, including synthetic polymers such as polypropylene (PP) (Tazuke & Kimura, 1978), polyethylene (PE) (Decker & Zahouily, 1998), poly (ethylene terephthalate) (PET) (Takahashi & Hotta, 2012), poly(butylene terephthalate) (PBT) (Salvagnini & Marchand-Brynaert, 2006), poly(methyl methacrylate) (PMMA) (Iguerb & Bertrand, 2008), polyurethane (PU) (Guan et al, 2000), and a series of natural polymers such as jute (Sawpan, Khan, & Abedin, 2003), cellulose (Kuwabara & Kubota, 1996), and sisal (Gangopadhyay & Ghosh, 2000). Controlling the affinity between the monomers and the polymeric substrates, and optimizing the reactivity of hydrogen in the substrates were both important (Deng, Yang, & Ranby, 2000b) in order to construct homogeneous Figure 9.3 Schematic of the sequential photo-induced living graft polymerization (Ma et al, 2000).…”
