Abstract
An increase in titanium corrosion resistance as a result of its diffus ion molybdenizing from a mixture with an oxide activating agent is sho wn. The two-phase coating formed is constituted of a low-titanium soli d solution in molybdenum and rutile, the latter is a product of the mo lybdenum oxide reduction by titanium. The coating acts as a passivatin g cathode substantially more effective than compact molybdenum. The co ating passivates titanium in 10% H2SO4 at 80 degrees C and increases i ts corrosion resistance by two orders of magnitude.
