چکیده
Abstract In this work, copper and zirconium were added into the Ti(Al)N matrix to form deposited on TiAl(Cu, Zr)N coating using RF magnetron sputtering system in order improve mechanical, wear performance, antibacterial activity. Results revealed that coatings have a dense structure with (111) preferential orientation. The exhibited fcc-TiN structure, whereas addition of Zr Cu induced appearance ZrN. solid solution strengthening increase compressive residual stress (− 2.54 GPa) Ti(Al, higher lattice strain (+ 0.1520) by improved hardness from 20.9 GPa. For tribological property, friction coefficient rate decreased (0.45, 5.9 × 10 −3 mm 3 /Nm) for TiAlN (0.29, 4.2 −5 Zr)N, respectively, high elasto-plastic H/E, H /E 2 (0.076, 0.121 ratios due low surface roughness, adhesion, nanocomposite structure. results indicated improves property coating. Although their lower than coating, Cu)N 9.2 at.% an excellent resistance good activity, which demonstrates its potential as candidate material biomedical application. Graphical

متن کاملA STUDY OF TiAlN COATINGS PREPARED BY RF CO-SPUTTERING
Using the reactive magnetron rf co-sputtering technique and a Ti target partially covered with a small Al plate, TiAlN coatings were made on c-Si in a reactive atmosphere of nitrogen and argon. Coatings were deposited on substrates at 22°C and at 150°C. The substrate temperature notably affected the thickness, crystalline grain size, and hardness of the coatings. We analyzed the dependence of b...
