In the present study, a forged CoCrMo (ISO 5832-12) has been subjected to pulsed plasma treatment in a N2/H2 atmosphere at low temperatures (below 500 °C). This treatment resulted in the formation of a layer composed by dispersed chromium nitride particles in a N-enriched metal matrix. The materials were tested for corrosion and tribocorrosion performance in 0.9 wt% NaCl at room temperature under...
The dry wear and tribocorrosion behaviour of pulsed plasma treated and non-treated Ni–Cr alloys sliding against alumina at 15N were investigated by using a reciprocating wear test rig equipped with an electrochemical cell. The pulsed plasma treatment produced a hardening diffusion layer of chromium nitride particles embedded in a metallic Ni–Cr matrix. The tests performed in dry conditions showed...
