“…The dry sliding condition exhibited the highest COF values, reaching approximately 0.25 at the end of the test. The COF values were lower for the specimens subjected to the tribocorrosion tests, due to the well-known lubricating action of the electrolyte, as reported by several authors [30][31][32]. The COF value of the OCP condition is higher than the…”

Surgical ASTM F139 stainless steel is used for temporary fixtures in the biomedical field. Tribocorrosion is a major concern in this application. The aim of the present work was to study the interplay between tribocorrosion behavior and the surface chemistry of the ASTM F139 stainless steel in phosphate-buffered saline solution (PBS). Sliding wear tests were conducted against alumina balls at different electrochemical potentials: open circuit potential (OCP), cathodic potential (−100 mV versus the OCP), and anodic potentials (+200 mVAg/AgCl and +700 mVAg/AgCl). The normal load was 20 N. The wear volume was estimated based on micrographs obtained from the wear tracks using confocal laser scanning microscopy. Moreover, the wear tracks were also examined by scanning electron microscopy (SEM). The surface chemistry of the ASTM F139 specimens was analyzed by X-ray photoelectron spectroscopy (XPS). The wear volume was dependent on the electrochemical potential, being maximized at +700 mVAg/AgCl. Delamination areas and grooves were observed in the wear tracks. Detailed assessment of the surface chemistry inside the wear tracks allowed identification of the main chemical species and their relative quantities, thus enabling correlation of the passive film composition with the observed tribocorrosion behavior.

“…Es crucial controlar los fenómenos de tribocorrosión, así como la naturaleza de las superficies friccionadas o desgastadas que han sufrido tensiones tribológicas [15]. La morfología y la composición química de las superficies de contacto juegan un papel crucial en la tribocorrosión [12], [16]. Otra variable crítica por considerar son las características químicas y electroquímicas de los materiales en contacto en el entorno corrosivo particular al que están expuestos.…”

“…Czagány et al [8] found the microhardness increases with increased P content in Ni-P coating after annealing treatment. Many studies mention electroless nickel coating has better corrosion resistance because electroless nickel coating is an amorphous coating and has better corrosion resistance than the crystalline phase [9][10][11].…”

Wear is considered the main criterion to evaluate the mechanical performance of electroless Ni-P coating in a radial micro journal bearing (copper alloy, inner diameter 3 mm × outer diameter 5 mm × length 7 mm). The study was carried out using different coating parameter combinations, namely, solution pH values of (6, 7 and 8), deposition time (10, 20 and 30 min) and bath temperature (60, 80 and 95 o C). The structure, surface morphology, hardness and wear resistance of the electroless Ni-P coatings were measured and analyzed. The optimum combination of coating parameters for minimum wear is a pH value of 8, deposition time of 30 min and bath temperature of 95 o C. Further, the structural changes of the coatings before and after annealing treatment (100 ~ 700 o C) in a vacuum ambient were investigated by means of X-ray diffraction, while their elemental composition and surface morphology were analyzed using an energy dispersive spectrometer and a scanning electron microscope. The Ni-P lms were subjected to annealing temperature at 400 o C for 1 hour, leading to recrystallization of the Ni matrix and the precipitation of Ni 3 P. The hardness increases with increasing annealing temperature to a peak of 960 HV at 400 o C and then decreases monotonously.
