In this paper, we consider the possibilities of using the atomic layer deposition process for producing decorative coatings based on aluminum oxide and titanium oxide on steel parts. The parameters of coatings based on aluminum oxide and titanium oxide of different colors were calculated. The calculations of the coating color and its optical characteristics are shown, and it is found that the developed software allows you to calculate the color of the coating. The properties of the resulting coatings have been studied and it has been experimentally established that these coatings can be used for chemical protection of surfaces.
