Abstract: Purpose – The application of coatings on metal substrates can provide an increase in corrosion resistance in the environment where the material is employed. The use of silane causes low environmental impact and may represent an alternative to replace chromates and phosphates applied as a pretreatment prior to surface painting. The objective of this study was to evaluate experimental parameters for the investigation of the formation of a vinyltrimethoxysilane (VTMOS) monolayer on 1010 carbon steel applying electrochemical techniques. Design/methodology/approach – A total of 24 types of coated samples were obtained, following three 23 factorial design of experiments (DOE), and one uncoated. The VTMOS monolayer was formed by hand dip process, followed by curing in a stove, using substrates of sanded, pickled and degreased 1010 carbon steel and hydrolyzed silane. Findings – The results of coated samples were satisfactory as compared to those of uncoated carbon steel, as the former were better protected against corrosion. Originality/value – This paper shows an evaluation of experimental parameters that influence the formation of a film of silane VTMOS on 1010 carbon steel by means of electrochemical techniques. The results indicated that the silane monolayer VTMOS promotes enhanced properties that prevent corrosion of 1010 carbon steel and the method of film formation directly influences the properties of such protection.
