    Corrosionpedia - What is Titanium Corrosion? - Definition ...

    Titanium is an established metal, when dealing with corrosion applications. Titanium is protected from corrosion by a thin film of oxygen on its surface. It reacts with titanium to form titanium dioxide, which acts as a barrier against corrosion. This barrier can only be broken if the titanium is placed in an environment that is very rich in ...

    Titanium corrosion

    Titanium is a very reactive metal that shows remarkable corrosion resistance in oxidizing acid environments by virtue of a passive oxide film. Following its commercial introduction in the 1950's, titanium has become an established corrosion resistant material. In the chemical industry, the grade most used is commercial-purity titanium.

    Corrosion of Titanium and Titanium Alloys

    The coupling of titanium with dissimilar metals usually does not accelerate the corrosion of titanium. The exception is in strongly reducing environments in which titanium is severely corroding and not readily passivated. In this uncommon situation, accelerated corrosion may occur when titanium is coupled to more noble metals.

    Corrosion - Wikipedia

    Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.

    It is well known that titanium nitride (TiN) coatings produced by physical vapor deposition (PVD) have a limited corrosion resistance, as a result of their intrinsic porosity. Some attempts have been made to improve corrosion resistance, by such measures as increasing film thickness.

    Corrosionpedia - Your Guide to Corrosion-Resistant Metals

    Titanium is an extremely useful corrosion-resistant material. Titanium obtains its corrosion resistance in the same way as aluminum and copper — through a passive oxide film that forms on its surface, protecting the remaining interior of the material. As a result, titanium can endure very harsh conditions for long periods of time.
