“…Ti 2 N phase was observed only for the PIII samples treated at highest temperature (800˚C) during 2 h whereas for the others the Ti 2 N phase was not identified. This phase was also noted by other authors [5][6].…”

“…This technique circumvents the line-of-sight and retained dose limitation inherent to conventional beam-line ion implantation, and is thus particularly suitable for large components possessing non-planar and complex geometries [3]. Most of the PIII processing was performed at low and moderate temperatures (< 400˚C) [4] and few works investigated the effects of the high temperature plasma immersion ion implantation (PIII) in Ti alloys [5][6]. Pichon et al [6] carried out PIII treatment of Ti-6Al-4V alloys using R.F.…”

Effects of plasma immersion ion implantation (PIII) of nitrogen on hardness, composition and corrosion resistance of Ti-6Al-4V alloy

Ti-6Al-4V samples have been treated by PIII processing at different temperatures (400-800˚C), treatment time (30-150 min) and plasma potential (100 and 420 V). Hardness measurements results showed an enhancement of the hardness for all implanted samples. XRD results detected the Ti 2 N phase and the best corrosion resistance was found for the samples processed at higher temperature and lower PIII time.

“…Despite their attractive mechanical and physical properties, the poor tribological behavior of titanium alloys, stemming from its low hardness, limited heat-transfer capability and susceptibility to oxidation, has limited their applications in many sliding components and tools [3,4]. Recently, a dramatic improvement in the wear resistance of titanium and its alloys has been achieved through various surface treatments [5][6][7]. Unfortunately, those modified surface layers often adversely affect the corrosion resistance of titanium alloys [8].…”

Effect of Al addition upon mechanical robustness and corrosion resistance of Mo5Si3/MoSi2 gradient nanocomposite coatings

A graded Al alloyed MoSi 2 /Mo 5 Si 3 nanocomposite coating was prepared on a commercially pure titanium substrate by double cathode glow discharge. The adhesion strength of the resultant coatings to substrate was enhanced by the graded design and the formation of a wider transitional layer between the coating and substrate. Moreover, corrosion resistance of the coatings increased through the addition of Al. First-principle calculations revealed that Al additions raised the corrosion potential of both MoSi 2 and Mo 5 Si 3 , and at the same time reduced the corrosion potential disparity between these two phases, thereby alleviating the occurrence of preferential corrosion.
