Application of commercially pure titanium coatings using HVOF thermal spray for machinery component restoration
Alloy 625 has been shown to be susceptible to crevice corrosion under tight metal to nonmetal crevices in both natural and treated seawater. Under similar conditions, commercially pure titanium (CP Ti) has been shown to be immune. Therefore, coating alloy 625 sealing areas with CP Ti is a potentially effective crevice corrosion countermeasure. Specialized thermal spray techniques were developed utilizing the high velocity oxy-fuel (HVOF) process to apply coatings of CP Ti to alloy 625 substrates in atmosphere. Coating quality was similar to plasma sprayed coatings of other less reactive, metals. Crevice corrosion tests were conducted and issues relating to implementation of HVOF thermal spraying on a production basis were considered.
