Abstract

Steel substrates were coated with TiAlSiN thin films with varying Si content using a combinatorial approach based in magnetron co-sputtering of TiAl and Si targets. The coatings were characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, and Raman spectroscopy. The films were amorphous and showed (Ti+Al)/Si ratios ranging from 0.7 (TiAl_3.0Si_5.6O_5.8N_5.1) to 4.2 (TiAl_3.6Si_1.1O_4.4N_2.6). The influence of the film composition on the surface oxidation and the corrosion resistance was investigated by near ambient pressure XPS and electrochemical methods. The films exhibited improved corrosion resistance with increasing Si-content. The adhesion properties were explored by investigating the interaction of the coatings with polycarbonate (PC). PC was melted onto the samples and the thickness of insoluble PC residue was investigated by ellipsometry, atomic force microscopy and nanoscale infrared spectroscopy. The results indicate that the incorporation of Si mainly promotes corrosion resistance, without altering the good anti-adhesive properties of TiAlN films.

期刊介绍： Thin Solid Films is an international journal which serves scientists and engineers working in the fields of thin-film synthesis, characterization, and applications. The field of thin films, which can be defined as the confluence of materials science, surface science, and applied physics, has become an identifiable unified discipline of scientific endeavor.
