“…It was not until the 1960s, however, that Ti6Al4V alloy began to be used as a surgical implant material because of its excellent mechanical properties (tensile strength of 860 MPa and yield strength of 790 MPa), and its lightness (specific gravity of 4.5 g/cm 3 ). Ti-based alloys are not the best from a biological point of view, however, since they corrode away when implanted; this disadvantage led to the discontinuation of the use of Ti6Al4V alloys for load-bearing applications.…”

A sol-gel dipping method has been utilised to deposit SiO 2 -CaO films onto Ti6Al4V alloy substrates. These layers were prepared by the dip-coating technique from a series of precursor solutions with different concentrations of glassy xSiO 2 -(1 − x)CaO (x = 0.8 mol) diluted with absolute ethanol. The characterisation of the films by a variety of techniques reveals differences in the textural properties and in the films'

“…There is extensive literature relating to the corrosion behaviour of titanium and Ti alloys in acidic media [5,6], in biomedical applications [7,8] and in sea water [9,10]. However, much less attention has been paid to their resistance to tribo-corrosion, where corrosion occurs in association with a mechanical degradation process (abrasion, erosion, cavitation, etc.).…”

The economic and effective operation of machinery and plant involved in uids handling is increasingly dependent on the utilization of materials that combine high corrosion resistance and good wear resistance. This paper focuses on erosion-corrosion where mechanical wear is due to impacting solid particles entrained in a liquid ow. The characteristics of commercially pure (CP) titanium (grade 2) and titanium alloy (Ti 5111) in erosion-corrosion conditions are assessed. There is much literature available on the corrosion behaviour of titanium and titanium alloys but little has been reported on corrosion in wear environments. The erosion-corrosion characteristics of each material at 18 and 50¯C were assessed using an impinging jet apparatus. The tests were performed in a 3.5% NaCl saline solution. Experiments were conducted to determine the mass loss by combined erosion-corrosion processes before independently determining the electrochemical corrosion mass loss and the mechanical mass loss. It has been shown that under erosion-corrosion conditions titanium and its alloys exhibit active corrosion behaviour, in contrast to passive behaviour when the tenacious oxide lm remains intact in static conditions. The synergistic effect between erosion and corrosion is signi cant and is dependent on the material.
