the improved corrosion and Tribocorrosion properties of tisin ag by thermal treatment
Surface & Coatings Technology, 2020Co-Authors: Yebiao Zhu, Minpeng Dong, Liping WangAbstract:Abstract TiSiN and TiSiN/Ag coatings were prepared by multi ion arc plating and annealed at 650 °C for 5 h. It was found that the annealed coatings had the better corrosion and Tribocorrosion properties than as-deposited coatings. The annealed TiSiN coatings exhibited a slower failure process in electrochemical impedance spectroscopy in test due to the reduction of porosities. Moreover, the annealing process can decrease the residual stresses in the coating which can lead to the low coefficient of friction during Tribocorrosion tests. What's more, Ag played an important role in Tribocorrosion experiment in TiSiN/Ag multilayer coatings. In general, the thermal treatment can improve the corrosion and Tribocorrosion properties of the coatings and annealed TiSiN/Ag coatings exhibited the best Tribocorrosion performance.

structure and Tribocorrosion properties of duplex treatment coatings of tisicn nitride on ti6al4v alloy
Ceramics International, 2019Co-Authors: Minpeng Dong, Yebiao Zhu, Chunting Wang, Lei ShanAbstract:Abstract To meet the performance requirements in harsh marine service environment, developing coatings with excellent trbibocorrosion performance is necessary. Herein, TiSiCN/nitride duplex treatment coatings are prepared by gas nitriding and multi-arc ion plating in turn in this work. The hardness and density are enhanced by nitriding treatment. Duplex treatment coatings exhibit more excellent mechanical properties possessing the maximum hardness values (33 GPa) and exceptional load bearing capacity (88 N) compared to TiSiCN coating. Meanwhile, the effect of wear on corrosion is significant and the action of corrosion determines the total degree of synergy in Tribocorrosion system. Furthermore, the friction coefficient is greatly reduced through duplex treatment coatings during Tribocorrosion test due to the good resistance to the seawater and the graphitization effect produced by TiSiCN layer.

Tribocorrosion Behavior of Aluminum/Alumina Composite Manufactured by Anodizing and ARB Processes
Journal of Materials Engineering and Performance, 2011Co-Authors: Roohollah Jamaati, Mohammad Reza Toroghinejad, Jerzy A. SzpunarAbstract:In the present work, Tribocorrosion behavior of Al/Al2O3 composite strips manufactured by anodizing and accumulative roll bonding (ARB) processes was investigated. The alumina quantity was 0.48, 1.13, and 3.55 vol.% in the aluminum matrix. Tribocorrosion experiments were conducted using a ball-on-plate tribometer, where the sliding contact was fully immersed in 1 wt.% NaCl solution. The composite sample served as a working electrode and its open circuit potential (OCP) was monitored before, during, and after sliding. In order to characterize the electrochemical behavior of the surface before and after sliding electrochemical impedance spectroscopy (EIS) was used and wear was also measured. Furthermore, the influence of quantity and distribution of reinforcement particles in the matrix on OCP and EIS was evaluated. It was found that the quantity, shape, size, and dispersion of alumina particles in the aluminum matrix strongly affected the measured Tribocorrosion characteristics. The results showed that inhomogeneous, lower quantity, fine, and acicular-shape alumina particles cause serious materials loss in Tribocorrosion process.

Influence of microstructure and texture on the corrosion and Tribocorrosion behavior of Ti–6Al–4V
Tribology International, 2009Co-Authors: Etienne Martin, M. Azzi, Gennady A. Salishchev, Jerzy A. SzpunarAbstract:Abstract In this paper, the corrosion and Tribocorrosion behaviors of Ti–6Al–4V alloy having different phase composition, texture and microstructure was investigated. Potentiodynamic polarization and electrochemical impedance spectroscopy measurements were performed to evaluate the corrosion behavior. Sliding wear tests under anodic and cathodic polarization conditions were made to assess the Tribocorrosion properties. SEM, OM, and XRD were used to characterize the microstructure, texture, and morphology of the samples. The corrosion resistance was found to depend on to the microstructure, as well as the texture of the surface. A bi-modal microstructure and prismatic texture showed the best corrosion behavior. However, when corrosion was coupled to sliding wear (Tribocorrosion), the hardness was found to be the controlling factor.

Improving the corrosion and Tribocorrosion resistance of Ni–Co nanocrystalline coatings in NaOH solution
Corrosion Science, 2009Co-Authors: Sh. Hassani, Keyvan Raeissi, M. Azzi, Mohammad Ali Golozar, Jerzy A. SzpunarAbstract:Abstract Ni–Co nanocystalline coatings were electrodeposited from a modified Watts bath. Increasing the deposition current density had no significant effect on structure, corrosion and Tribocorrosion behavior of the coatings. Adding saccharin into the bath reduced the grain size, increased the hardness, changed the texture component from (2 0 0) to (1 1 1), smoothed the surface morphology, increased the corrosion resistance and improved the Tribocorrosion behavior of coating. Presence of sodium lauryl sulfate in the bath increased the corrosion resistance of coating by producing a more compact surface morphology. However, the coating showed low Tribocorrosion resistance, probably due to its lower hardness.
