AlCr and AlCrFe coatings; Magnetron sputtering; Corrosion resistance
AlCr and AlCrFe coatings were deposited on carbon steel C45 and titanium grade 2 substrates via magnetron sputtering. The coatings have an amorphous structure, a thickness of 3-4 μm, and are uniform in terms of thickness and chemical composition. No major defects were observed at the interface, but there was no diffusion at the interface, indicating adhesive bonding and relatively low adhesion. The coatings exhibit a hardness of about 8-10 GPa and a Young's modulus above 150 GPa, slightly higher for the steel substrate. The coatings provide good corrosion resistance for the steel substrate but underperform for the Ti grade 2.
In this work, AlCr and AlCrFe coatings were deposited via magnetron sputtering on technical substrates of carbon steel C45 and titanium grade 2. The coatings feature an amorphous structure, a thickness of 3-4 mu m, and are uniform in terms of thickness and chemical composition. No major defects were visible at the interface; however, there is no diffusion at the interface, which indicates the adhesive type of bonding and results in relatively low adhesion. The coatings are characterized by a hardness of about 8-10 GPa and a Young modulus above 150 GPa. Both values are slightly higher for steel substrate. The coatings assure good corrosion resistance for steel substrate while underperforming those of Ti grade 2.
