“…This oscillation of friction coefficient is resulted from the hard substrate (GCr15) ploughing into the soft bulk material (NiTi alloy). 19) After MAO treatment, the friction coefficient becomes steady due to Al 2 O 3 coating preparation on NiTi alloy.…”

The ceramic coating was prepared on the NiTi alloy by Micro-arc oxidation (MAO) in a sodium aluminate (NaAlO 2 ) solution at constant current density. The surface of the coating displays a rough, porous structure. Thin-film X-ray diffraction shows that the only Al 2 O 3 phase can be confirmed in the coating. Potentiodynamic polarization curves indicate that the corrosion resistance of the Al 2 O 3 coating is better than that of uncoated NiTi. The amount of Ni leached from coated NiTi sample is 20.97% of that from the uncoated NiTi sample after immersion 40 d. The Tribological behavior of uncoated and coated NiTi alloy was evaluated using a computer-controlled ball-on-disk WTM-1E tribometer.

“…The coatings may flake away under the influence of mechanical stresses and vibration. Several other techniques have been investigated to obtain strongly adherent coatings with a large surface area such as plasma spray deposition [28,29], plasma electrolytic oxidation (PEO) [30] and the electrophoretic deposition (EPD) method [31].

The La 2 NiO 4 film was synthesized on the 304 stainless steel (SS) mesh. The hydrogen reduction of La 2 NiO 4 generated homogeneous nanocatalyst particles (probably Ni/La 2 O 3 ) over which methane was cracked, producing carbon nanotubes/microfibers and hydrogen. The carbon nanotubes/microfibers were strongly bonded to the SS mesh. It was observed that the methane conversion always reached its maximum at the cracking temperature of 750°C regardless of its concentration varying from 5% to 100%. The cracking of 5% methane diluted in nitrogen generated multiwalled carbon nanotubes while the cracking of 10-100% methane resulted in the formation of carbon solid microfibers together with globular carbon particles. Higher concentration of methane created thicker carbon fibers and a 30% concentration of methane resulted in the highest deposits of carbon on the mesh. After a compressed air blow and ultrasonic treatment, the carbon deposits were still strongly adhered to the mesh. As a result of the carbon tubes/fibers coverage, the specific surface area of the SS mesh was enhanced significantly from 0.03 m 2 /g to 21-45 m 2 /g. XRD, HRTEM and Raman studies confirmed that the carbon products were of graphitic structure. Such advanced mesh material would have great application potential in industrial catalysis and other areas.

“…An additional factor that may affect the scratch response is the coating thickness [44]. However, Holmberg et al [45] showed that thickness plays a less important role compared to the elastic properties of the coating.…”

The effect of metal alloying on mechanical properties including hardness and fracture toughness were investigated in three alloys, Ti~0 .33 Al 0.50 (Me)~0 .17 N (Me = Cr, Nb and V), and compared to Ti 0.50 Al 0.50 N, in the as-deposited state and after annealing. All studied alloys display similar as-deposited hardness while the hardness evolution during annealing is found to be connected to phase transformations, related to the alloy's thermal stability.
