Purpose: The paper presents the results of mechanical activation of the surface on oxide layer thickness after heat treatment of TU6Al14V ELI alloy. Design/methodology/approach: Specimens were made from 5 mm diameter rod cut into semicircular slices. The samples were mechanically activated throughout mechanical treatment of the surface: one sandblasted with glass beads during 5 minutes and other ground with sandpaper grit 40, 180, 220 and 800 during 7.5 and 15 minutes. Findings: Then microstructure of specimens etched with Kroll solution was observed using an optical microscope and roughness parameters of the surface were measured. Research limitations/implications: Afterwards heat treatment (550°C, 5 hours) was conducted, then roughness parameters and thickness of the oxide layer were measured by means of a scanning microscope. Practical implications: The conducted research showed up that mechanical activation of the surface which cause an increase of surface development results in greater thickness of the oxide layer which is formed during heat treatment. Nevertheless, mechanical activation that results in a decrease of surface development, such as polishing, results in a decrease of oxide layer thickness. Originality/value: The results of the research can be used to obtain the desired thickness of the oxide layer in the production of the elements that require increased wear and corrosion resistance.
