“…4 gives comparative wear rate of the coatings (A, B, C and F). The wear rate has similar order of magnitude (10 -5 -10 -4 mm 3 .N -1 m -1 ) as literature reports (between 10 -6 and 10 -4 mm 3 .N -1 m -1 ) [10,14,15]. The wear rate decreases as the content of the particles increases.…”

“…High temperature wear behaviour of Ni matrix based composite Ni/SiC [14] and Ni-P/BN [15] coatings has also been reported. Although some investigations have been carried out on the elevated temperature surface property and wear characteristics of Ni-P/SiC deposit, studies on the effect of the incorporated particle concentration involving matrix-ceramics qualitative investigation are limited.…”

The investigation is focused on the wear behaviour at elevated test temperature of composite Ni-P/SiC deposit, with varying concentration of the reinforcing SiC particles. The phase evolution measured by X-ray diffraction suggests slight crystallisation during wear testing at 200 °C. In coating without reinforcing particles, adhesive wear is accompanied by microcracks. The thermal heat generated and the cyclic loading could have induced subsurface microcracks. Owing to the effective matrix-ceramics system in composite coatings, fine grooves, abrasive polishing and uniform wearing are observed. Reinforcing particles in the matrix hinder microcrack formation and significantly reduce the wear rate. Triboxidation is confirmed from energy dispersive X-ray spectrometry.

In this study, silver particles were embedded in Ni-P matrix by electroless deposition on medium carbon steel substrates to produce Ni-P-Ag composite coating. The structure of as plated and heat treated coatings were evaluated by X-ray diffraction analysis. Tribological properties of the coatings were investigated by pin on disc test method using 52100 steel pin as counter body at room and high temperatures. Three-dimensional optical profiler was employed to determine wear rate of the deposits. Surface morphology, cross-section of coatings and wear scars were studied by using scanning electron microscopy equipped with EDS analysis. The results showed that nanocrystalline Ni-P-Ag composite coating had a self-lubricating property at room and high temperatures. It was concluded that diffusion and nucleation of silver on the surface of Ni-P-Ag coating and also formation of a silver thin layer on the sliding surface led to decrease the friction coefficient of Ni-P-Ag coating.

“…Rf-GDOES is widely used to analyze the elemental distribution as a function of the depth of several type of coatings, from nanometric to micrometric size in thickness, as for example: hot dipped coatings, 18 galvanic coatings, 19,20 sol-gel, 21,22 and Physical Vapour Deposition (PVD) 23 and Atomic Layer Deposition (ALD) coatings. 24 However, Rf-GDOES has limited lateral resolution because the obtained craters are typically 4 mm in diameter.…”

AA 3XXX alloys are widely used in heating, ventilation, and air conditioning (HVAC) field. Diffusion joining using a filler metal together with flux is employed in some applications as for heat exchangers. In this work, the effect of diffusion of a Zn‐based flux on both microstructure and electrochemical behavior has been investigated. In particular, an AA3xxx was coated with a Zn‐rich flux and subjected to controlled atmosphere brazing (CAB). Glow discharge optical emission spectroscopy (GDOES) composition profiles were acquired in order to determine the Zn distribution in the diffusion layer. The GDOES was also employed to produce a controlled erosion of the surface in order to obtain craters with defined depths in the Zn diffusion layer, in which electrochemical analyses could be performed. The Volta potential maps at different depths in the Zn diffusion layer were obtained by scanning Kelvin probe force microscope (SKPFM). The Zn diffusion layer was also investigated by means of Scanning Electron Microscope‐Energy Dispersive X‐ray Spectroscopy (SEM‐EDXS) and the chemical composition of the phases present in the regions was investigated by SKPFM. Finally, the electrochemical microcell was used in the produced craters in order to determine the electrochemical behavior along the Zn diffusion profile. SKPFM and microcell results showed a correlation between the Zn content and the electrochemical properties. In particular, a higher Zn content in the diffusion layer leads to an increase of the Volta potential difference between the intermetallic particles and the matrix. The electrochemical measurements also showed that the Zn diffusion layer provides galvanic protection to the underlaying aluminum alloy.
