Short Times

An occluded corrosion cell configuration and polarization program were developed in order to measure the crevice corrosion resistance of implant alloys. 316 L stainless steel was used in establishing that the crevice cell configuration was convenient, reproducible, free of unwanted crevices, and suitable for laboratory measurements requiring relatively short times.

Small amounts of nickel are added to titanium to improve the crevice corrosion resistance but this results in an alloy which has sheet fabrication difficulties and is subject to the formation of large Ti2Ni precipitates. These large precipitates can serve as local corrosion sites; but in a smaller more widely dispersed form, they can have a beneficial effect on crevice corrosion resistance. The purpose of the present work is to show that the addition of a small amount of Mo to the Ti-1.5Ni alloy reduces the Ti2Ni precipitate size and produces a more elongated grained microstructure. It has recently been reported that small additions of Mo to Ti-0.8 to lw/o Ni alloys produce good crevice corrosion resistance and improved fabrication properties.
