High temperature properties of the Cr-Nb-Al-N coatings with increasing Al contents
Li, W. Z.; Polcar, T.; Evaristo, M.; Cavaleiro, A.Cr-Nb-Al-N coatings with Al content from 0 to 12 at.% were deposited by d.c. reactive magnetron sputtering. The coatings were annealed in protective atmosphere at 800 and 900 °C for 1 h and exposed to air at 800, 900 and 1200 °C for different times. The chemical composition, structure, microstructure, hardness and adhesive/cohesive strength of the coatings, in as-deposited and annealed conditions, were investig...
Effects of the constitution of CrON diffusion barrier on the oxidation resistan...
Li, W. Z.; Yi, D. Q.; Li, Y. Q.; Liu, H. Q.; Sun, C.The duplex coating system of a NiCrAlY overlayer with a CrON diffusion barrier with different phase contents was deposited by AIP method. The duplex coatings were characterized regarding their microstructure, and the ability of the diffusion barrier was evaluated. The oxidation resistance and the interfacial strength of the duplex coatings were investigated. The results indicated that the duplex coating system ...
