Abstract:

Screen printing (SD) is a simple and well-developed coating technology widely used today, but it is time consuming, expensive, and not environmentally friendly due to the organic solvents used in the technology. The aerosol deposition (AD) coating process can be an alternative to this method, due to the homogeneous properties (e.g. density, roughness, etc.) and environmental friendliness of the deposited coatings. This paper presents the results of a comparative mechanical tribological study of metal coatings (Cu, Al) deposited on a ceramic substrate (BaTiO3) by screen printing and aerosol deposition technology. To compare the coating technologies, we examined the tribological behavior of coatings and the damage mechanism by instrumental scratch test.
