“…Due to their high wear resistance and low cost of ceramic powders, composite materials such as Ni-SiC manufactured by electro-codeposition method have been investigated to a greater extent and successfully commercialized in the automotive and aerospace industry, particularly for the protection of friction parts [5,6]. This process can be carried out using either Conventional Electro-Co-Deposition technique (CECD), in which the electrodes are positioned vertically in the plating cell, or by Sediment Electro-Co-Deposition (SECD), in which the electrodes are positioned horizontally one over the other with sufficient inter-electrode distance, so that the particles settle on the electrode surface as sediment on the cathode as the metal deposition progresses [7,8].…”

The effect of various surfactants on the volume% codeposition of SiC in a nickel matrix was evaluated. Of the various surfactants tried, tetra methyl ammonium hydroxide (TMAH) was found to be the best for improving the quality of the deposits as well as the homogenous distribution of particles and with reasonable volume% of silicon carbide incorporation in the matrix. Composites were produced using 1 µm and 50 nanometer size powders. The effect of silicon carbide concentration and bath operating variables on the volume% of SiC incorporation in the deposit and the deposition rates were estimated. Substantial improvement in mechanical properties such as hardness and wear resistance was obtained with the nano SiC composite compared to the micro SiC composite.

“…There are some documented studies on the tribological properties and the electrochemical behavior of Ni-P composite coatings [1,2,12,[30][31][32][33]. According to these papers, the corrosion resistance of Ni-P coatings can be optimized by the incorporation of particles in the deposits and it depends on factors such as the particle type, size and concentration, and process parameters.…”

This paper describes the effects of heat treatment and of SiC particle incorporation on the electrochemical behavior and physical structure of Ni-P (17 at% P) composite coatings. The deposits were obtained by electrodeposition with various contents of SiC particles in the plating bath and heat treated at 420 8C. The physical structure was investigated by inductively coupled plasma atomic emission spectrometry (ICP-AES), X-ray diffraction (XRD), and scanning electron microscopy (SEM -image analysis). The electrochemical behavior of the resultant composite coatings was determined by chronopotentiometry, electrochemical impedance spectroscopy, and potentiodynamic measurements in 0.6 M NaCl solution at pH 6. Heat treatment showed a positive effect on the electrochemical behavior of Ni-P coatings, shifting the open circuit potential toward less active potentials. The incorporation of SiC particles inhibited pit nucleation on the Ni-P composite coating, with or without post-heat treatment. However, heat treatment in the Ni-P-SiC seemed to induce cracks in the metallic matrix, initiating at the SiC particles, possibly caused by the contraction in the metallic matrix. The cracked structure promoted localized corrosion, while coatings without heat treatment resulted in a general and uniform corrosion.

“…Other designs feature the sample moving against the stationary counter-body. Furthermore, while linear reciprocating motion is common, a few systems employ a circular track, where the pin or ball moves on the sample in a continuous or intermittent circular path, with or without reciprocation [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. In some cases, a warm water bath surrounds the electrochemical cell to mimic body temperature [25,29,33].…”

“…• All electrochemical cells, including the sample holder, were constructed of materials resistant to corrosion, such as polyvinyl chloride (PVC) [21-23, 27, 31], Teflon [24], acrylic [34], and polypropylene [30], while many others did not mention the choice of material [25,26,28,29,32,33,35,36]. Similar to the considerations for the counter-body, any leached material from the electrochemical cell into the corrosion solution may alter the tribological dynamics (third-body wear) and reaction kinetics.…”

Orthopedic and dental implants experience the synergistic effect of wear and corrosion, i.e., tribocorrosion, which has been a major contributor to the premature failure of implants. This work focuses on the development of a compact and cost-effective tribocorrosion apparatus for the investigation of fretting and wear. The custom-built apparatus is validated with an analysis of the tribocorrosion behavior of Ti6Al-4V disks in artificial saliva (pH = 6.5, T = 37°C). Electrochemical impedance spectroscopy, potentiodynamic, free potential, and potentiostatic analyses were used for electrochemical characterization of Ti-6Al-4V disks. White light interferometry and scanning electron microscopy were used to analyze wear scars on the Ti-6Al-4V disks. Total wear loss was calculated to be 12.4 ± 1.5 lg, and the synergistic weight loss ratio (0.78 ± 0.1) showed that Ti-6Al-4V disks experience synergy of wear and corrosion, with wear being the dominant component.
