The aim of the research was to study the effect of methane on the kinetics of anodic etching of aluminium in solutions of sodium chloride, sulphuric acid and potassium hydroxide to determine the nature of this effect and the possibility of its use for practical purposes. It is shown that cathode and anode processes are not accompanied by electrochemical transformations of methane. The influence of methane on the kinetics of anodic dissolution of aluminium in 0.1 M solutions of sodium chloride, sulphuric acid and potassium hydroxide was investigated. It is established that in the presence of methane, regardless of the nature of the electrolyte, the speed of anodic dissolution of aluminium is significantly reduced. In addition, there is a slowdown of the cathode processes. The efficiency of exposure to methane adsorption increases upon pre-activation of the aluminium surface due to cathode polarization, especially in sodium chloride solutions. Methane adsorption is explained by the presence of an active aluminium surface and the formation of methane clusters in the pores with the participation of a hydrated oxide film. The ability of methane to inhibit the cathode and anodic processes on aluminium in various environments may find application in anodizing, corrosion protection, selective anode etching of aluminium to obtain a highly developed surface, or to restore contours of deformed metal sections in forensics.
