Abstract
The corrosion resistance of pressed and sintered (PAS) titanium diboride has been compared with that of electrodeposited titanium diboride. Anodic polarization studies in 0.5 M sulfuric acid showed that PAS titanium diboride corrodes at rates of 50 to 100 times greater than electrodeposited titanium diboride. Corrosion rates were determined for PAS titanium diboride in hydrochloric acid, sulfuric acid, and substitute ocean water, under a wide variety of conditions. The corrosion rates in oxygen-aerated sulfuric acid solutions were characterized by a maximum of 250 milligrams per square decimeter per day at 0.3 M. This is an order of magnitude greater than the corrosion rate in the corresponding helium-aerated solution.
