Generation of Ammonia during Wear Processes in Adhesive Wear of Titanium

We report a short note of preliminary and new experimental results that the generation of ammonia (i.e. nitrogen fixation) can occur on tribologically activated surfaces formed as a result of the frictional sliding of pure titanium when this is performed in a mixed gaseous environment of dinitrogen...
