tialn cu nanocomposite coatings deposited by filtered cathodic arc ion plating
Journal of Materials Science & Technology, 2017Co-Authors: Lei Chen, Z.l. Pei, Jinquan Xiao, Jun Gong, Chao SunAbstract:TiAlN/Cu nanocomposite coatings with Cu concentration of 0–1.4 at.% were deposited on the high-speed steel (HSS) substrates by filtered cathodic arc ion plating technique. The chemical composition, microstructure, morphology, adhesion strength, mechanical and tribological properties of the TiAlN/Cu coatings were characterized and analyzed. The results reveal that the coating structure and properties depend on not only the Cu concentration, but also the Deposition Condition. The addition of Cu significantly decreases the grain size and weakens the texture in the TiAlN/Cu coatings. With increasing the Cu concentration, the coating hardness decreases slightly from 30.7 GPa of the pure TiAlN coating to 28.5 GPa of the TiAlN/Cu coating with 1.4 at.% Cu. All the TiAlN/Cu coatings present sufficient adhesion strength. In addition, the existing state of additive Cu in the TiAlN/Cu coatings is also investigated.

effect of tartrate content on aging and Deposition Condition of copper tin electrodeposits from a non cyanide acid bath
Surface & Coatings Technology, 2002Co-Authors: Ivani A. Carlos, E. D. Bidoia, Eliria Maria De Jesus Agnolon Pallone, Moacyr Rodrigo H. De Almeida, C.a.c SouzaAbstract:The effect of the presence of tartrate additive on the chemical stability of a Cu–Sn acid bath was evaluated. It was observed that this additive hinders decomposition of the Cu/Sn Deposition bath with storage time, since the decrease in electrochemical efficiency was attenuated. In addition, it was observed that optimal galvanostatic Deposition with or without tartrate occurs at approximately 11 mA cm−2. However, in the presence of tartrate the Deposition charge was lower, leading to lower energy consumption. SEM analysis showed that the tartrate added to the plating bath caused a marked change in the morphology of the Cu/Sn films obtained galvanostatically.
