Electrochemical investigations were made and the corrosion rate of Ti-Al-Ni and Ti-V-Nb system alloys in chloride-containing and acid solutions was determined. The sensitivity of them to corrosion cracking in a sulfuric acid solution was also evaluated. The media were a 3% NaCl solution and a 20% H/sub 2/SO/sub 4/ solution. The uniform corrosion rate of the alloys alloyed with nickel in 20% H/sub 2/SO/sub 4/ solution was parctically two orders of magnitude less than of the nickel-free ones. For parts operating in low-concentration acid and chloride solutions in which acidification is possible, alloys of the Ti-Al-Ni and Ti-V-Nb systems may be promising.
