The influence of chemical groups on the mechanical properties of SiCNH coatings deposited on 7075 aluminum alloy

Influence of gas mixture during N+ ion modification under plasma conditions on surface structure and mechanical properties of Al–Zn alloys

“…These conclusions are in agreement with our other study [41]. Preceded by the process of Al-Zn alloy surface modification in the conditions of only nitrogen flow, regarding the usage of the reaction mixtures with hydrogen, results in decreasing its portion within the of C=C, C=N bonds in the structure of SiCNH coatings.…”

“…Especially in the case of K3 there are strong vibrations from the -Si-N-group, which may be easily formed during regrouping reactions, in the presence of thermally dissociated H + radicals. That causes physical contact, and better distribution of stress at the substrate-coating interface and at last a decrease in coefficient of friction value [41]. Therefore, these results are consistent with the data of examination of the analyzed structure roughness with AFM method (wide supra Fig.…”

“…1b) significantly improves the interactions on coating-Al alloy boundary (for all tested samples, independently on the N 2 content in gas mixture). Similar results, proving profitable stress distribution at the substrate and coating interface after an application of nitrogen ion modification process, have been observed in the papers in the range of modification of metals and aluminum alloys [40][41][42][43].…”

Electrochemical corrosion performance of friction stir processed cold spray metal matrix composite coatings on AZ31B magnesium alloy under sodium chloride environment

“…These parameters characterise CS as a lower temperature, higher velocity method with the notable merit of no oxidation or phase transition, allowing the coating material to keep its original characteristics [4][5][6]. In comparison with other popular coating methods (high velocity oxy fuel and atmospheric plasma spray), bonding in CS occurs in a solid state with a plastically deformed state instead of melting at extremely elevated temperatures [7][8][9][10]. Because of these benefits, it can be used to produce various reinforcements of the ceramic element metal matrix composites (MMCs) such as Al 5056-SiCp [11], aluminiumalumina [12], and Cu-CNT-SiC [13].…”

Laser plasmochemical synthesis of hard protective SiCN films

“…Its resistance to high temperatures and corrosive environments as well as other properties make it a perspective material for a wider field of applications. [6][7][8][9][10][11][12][13][14][15]…”
