Abstract
The nature and mechanism of titanium alloy crevice corrosion are described, along with a review of six primary factors known to influence titanium’s susceptibility to crevice attack. These, often interacting, factors include temperature, solution chemistry/pH, nature of the crevice, alloy composition, metal surface condition, and metal potential. A number of practical methods for effectively preventing titanium alloy crevice attack are offered as well, all of which promote titanium passivation through ennoblement within crevices. Avoidance of contact with gasket and sealants which may be chemically incompatible with titanium is also discussed and is a prerequisite for successful alloy performance.
