In a dual phase (DP) steel, an increase in the martensite volume fraction leads to a decrease in its carbon content, and hence, elucidating the effect of martensite content on the mechanical and tribological behaviors is not possible. For the first t

Tribocorrosion tests were conducted on Ti6Al4V against alumina in phosphate buffered saline solution under normal loads of 3−30 N (corresponding to the maximum Hertzian contact pressures of 816−1758 MPa) using a ball-on-disk tribometer. Nano-hard

Ferrite grain refinement of a ferritic–martensitic dual-phase (DP) steel was found to be quite effective in enhancement of tensile properties, work-hardening behavior, and quench aging (natural aging) phenomenon. The precipitation strengthening eff

Corrosion, erosion and synergism behaviors of Sanicro28 (UNS–N08028) stainless steel have been studied during erosion-corrosion using a slurry impingement rig. The erosive-corrosive slurry solution consisted of 3.5% NaCl saline water and 30 g/l SiO

It is known that impingement of solid particles on the surface of alloys could cause an increase in corrosion rate during erosion-corrosion. The increase in corrosion rate by erosion could be studied using the common electrochemical technique of pola
Ti–6Al–4V has prominent physical and mechanical properties, which nominate it for various engineering applications. A drawback of the alloy, however, is low scratch and wear resistance, which can be improved by a diffusion treatment. Oxygen diffu

Effects of jet velocity, sand concentration and impingement angle on the surface roughness of Al-brass alloy were investigated after erosion and erosion–corrosion tests. The tests were performed using a jet impingement rig. The eroded surfaces were
