Research Abstract

Tribo-coating films formed by tribo-coating process have nano composite structure in which the soft-metal of nano size are distributed in the hard matrix composed of friction pair materials. Due to the structure of the films thinner lubricious film is easily self-formed during friction. It is the reason why tribo-coting films can give super-low friction. On the basis of the understanding the low friction mechanisms of tribo-coating films, new composite coating that represents the structure of tribo-coating film is created. The newly introduced composite coating films provide friction reduction to one half of that of molybdenum disulfide, which is the most popular solid lubricant for space mechanisms.
