Optimization of cold plasma process parameters for organosilicon films deposition on carbon steel: Study of the surface pretreatment effect on corrosion protection performance in 3 wt% NaCl medium

Hexamethyldisiloxane (HMDSO)‐ and hexamethyldisilazane (HMDSN)‐based plasma polymeric coatings are compared as elements of multilayer barrier coatings, consisting of an alternating structure of organosilicon and silicon oxide layers. Furthermore, these coatings are examined with regard to their deposition rate, critical layer thickness, surface roughness, atomic composition, and gas permeability. It is investigated how these attributes correlate in the overall barrier performance of a multilayer coating system. The concluded examinations show that HMDSN delivers best overall barrier performances as a precursor at high energy densities. For lower energy densities, the use of HMDSO is preferable. Intermediate layer thickness should not exceed six nanometers for best barrier performance in the given experiment configuration.

“…Among recent techniques used to deposit polymer coatings on material surfaces, plasma enhanced chemical vapor deposition (PECVD) (Ardic & Gifvars, 2017;Bowen & Cheneler, 2019;Fermi et al, 2019;Krtouš et al, 2021;Mitev et al, 2016;Zhou et al, 2020). It is a unique technique for fabricating corrosion-resistant polymer coating from a variety of organic materials (Aramaki, 1999;Esbayou et al, 2018;Grundmeier et al, 2003;Jaritz et al, 2019;Natishan et al, 1995;Singh-Beemat et al, 2013;Wang et al, 1996). The obtained coatings are pinhole-free and highly crosslinked (Martin, 2009).…”

Plasma- polymerized coatings were successfully applied on aluminum alloy, AA2024, surface for corrosion protection. The plasma polymerization process was carried out by low pressure microwave plasma at room temperature. The effect of microwave plasma power on the corrosion resistance of polymer coatings was investigated using the potentiodynamic polarization technique. As the microwave plasma power increased, the relative protective efficiency increased. Polymer coatings on alloy surfaces suppressed both anodic and cathodic reactions. The increment in protective efficiency was due to a higher degree of cross-linking in the coating. These findings suggest that the toluene polymer coatings provide a considerable protection barrier for aluminum alloys.

“…In another work, Esbayou et al 30 deposited organosilicon films using plasma-enhanced chemical vapor deposition (PECVD) from the precursor 1,1,3,3-tetramethyl disiloxane (TMDSO) on carbon steel. The authors studied the influence of different surface pretreatments, which were the amorphous phosphating, the exposure to Ar or N 2 plasmas, on the performance of the obtained coatings.…”

Because of its excellent properties, carbon steel is a material widely used in several sectors. However, it is easily corroded when exposed to the environment. Seeking to remedy this problem, the possibility of coating carbon steel with SiO x /SiO x C y H z films generated by deposition and oxidation in low-pressure plasmas was investigated. Specifically, the effects of excitation power of the oxidation plasma on layer thickness, chemical structure, elemental composition, and barrier properties of the obtained coatings were investigated. The coating of the steel with the SiO x C y H z film, generated by plasma in an atmosphere of hexamethyldisiloxane (HMDSO), increased the total resistance to the passage of electric current, measured by electrochemical impedance spectroscopy. However, under the condition of moderate power oxidation (50 W), the results point to the creation of a bilayer system with high resistance to electrochemical attack compared to the SiO x C y H z film, even though its thickness is less than this.
