Nickel‐free, high‐nitrogen austenitic steels (AHNS) have been introduced for biomedical applications, with encouraging results in terms of mechanical and corrosion properties. Here, we tested the corrosion resistance of a nickel‐free high nitrogen steel (FeCrMnMoN0.9) in bovine serum solutions containing 0 or 3 g/L hyaluronic acid (HA), and 0, 3, or 30 mM hydrogen peroxide (H2O2) simulating no, moderate, or strong inflammatory conditions, respectively. Nondestructive electrochemical measurements (open circuit potential [OCP], linear polarization resistance “RP”, and electrochemical impedance spectroscopy) were run in triplicate over 10 hr. The presence of HA had no significant effect either on the stabilized OCP values, or on the corrosion resistance of FeCrMnMoN0.9. Increasing H2O2 concentrations shifted the OCP to more electropositive values; the corrosion resistance decreased only at a 30 mM H2O2. Final RP values at 0, 3, and 30 mM H2O2 resulted in 1598 ± 276, 1746 ± 308, and 439 ± 47 kΩ cm2, respectively. These values were 4–14 times higher, than the RP values measured on LC‐CoCrMo in our previous study, conducted under identical conditions. While these findings are encouraging, future studies need to focus on tribocorrosive properties of the AHNS to evaluate its applicability in joint replacement.

“…In many studies, biomolecules can act as lubricating medium to slow down the wear, especially in metal-metal frictional system [20]. Some reports revealed the protein molecules can transform to lubricating tribofilm under load and friction [21]. However, in DLC-Ti6Al4V friction system, the wear reduction effect of biomolecules is not applicable.…”

A route to reducing the wear of the metal counterpart in the friction of meatal against diamond-like carbon (DLC) is to form a lubricating tribofilm on the metal counterface. However, in liquid lubricating conditions, the formation of tribofilm can be influenced by both the lubricating medium and the counterpart material. Here we report the effect of lubricating biomolecule and doping fluorine element on the formation of tribofilm in fluorinated DLC (FDLC)-Ti6Al4V friction system. A group of ball-on-disc frictional experiments with different sliding speeds and normal loads were performed in phosphate buffer solution (PBS) and bovine serum albumin (BSA) solution. The results showed the formation of tribofilm was inhibited by the absorption of biomolecules on the frictional surface, thus improving the friction coefficient and wear of Ti6Al4V counterpart. Doping fluorine into DLC film also can restrain the formation of tribofilm on Ti6Al4V counterface. As a result, tribofilm is difficult to form when Ti6Al4V counterface slides against FDLC in BSA solution. Fluorinated DLC film should be considered carefully for the anti-wear use in body fluid containing biomolecules because it might cause severe wear of the counterpart material.

Cubic transition-metal nitride coatings have been regarded as promising candidates for of marine engineering components in seawater environments. However, the excellent seawater lubrication is hard to achieve due to contradictory relations of hardness and toughness, as well as unstable behaviors at sliding contact surface. As discussed in our previous work about the enhanced tribological behaviors of hard yet tough CrN/Si3N4 multilayer coatings[14], superhard yet tough coatings are highly desired to improve wear resistance and durability in aggressive solutions. Here we report Ti-C-N coatings with Ti(C,N) and small sp2-C phases deposited by high power impulse magnetron sputtering exhibit simultaneously superhardness of 40.2 GPa and favourable toughness (without radial cracks in HRC indentations). Superhard yet tough Ti-C-N coatings show excellent seawater-lubricating behaviors with extremely low friction coefficient of 0.03 and smooth wear morphologies in 3.5wt.% NaCl aqueous solution. The enhanced tribocorrosion performance are attributed to superhard yet tough properties resulting in the increased resistance of crack initiation and propagation, which restrains synergistic actions of wear and pitting corrosion. In addition, stable self-lubricating amorphous carbon phase at sliding contact surface reduce friction and wear in seawater.
