A mechanochemical reconditioner package has been investigated in our laboratory which could be used to generate an in situ protective layer on worn metal surfaces as a result of mechanochemical reactions between worn tribosurfaces, wear debris and a special reconditioner formulation. The main constituent in the reconditioner formulation chemistry is magnesium silicate hydroxide, Mg6(Si4O10)(OH)8. HRTEM analyses have displayed that the protective layer consists mainly of cementite nanocrystals with crystalline anisotropy. Nanoparticles of magnet iron oxide (Fe3O4) and iron peroxide (FeOOH) are dispersed on the habit planes of nanocrystalline cementite matrix. The protective layer obtained exhibits very smooth top surface and excellent tribological characteristics.
