Ti 6 Al 4 V titanium, due to its high mechanical properties, lightness and good resistance to corrosion, is a potential candidate for structural material for manufacturing a 3 000 meter long drilling riser. This paper shows the influence of surface preparation on the corrosion and corrosion-fatigue properties of Ti 6 Al 4V alloy.

The influence of temperature, acidification, H2S contamination and abrasion on the rest potential and galvanic coupling (with steel) have been investigated. SCC tests were also performed. The beneficial effect of mechanical surface treatment of Ti 6 Al 4 V alloy in corrosion-fatigue tests in outlined.
