Ferrocene derivatives in boundary lubrication

Model friction and thermal investigations have been carried out to study the most reactive of the ferrocene derivatives tested so far-1,1'-diethyl-2-thia[3]ferrocenophane. The analysis of the results obtained from model friction investigations points to the reactive character of both sulphur and ferrocene iron in reactions with the surfaces of the samples tested. The presence of ferrocene derivative reaction products on the surface of the metal samples studied has been confirmed by means of instrumental analytical methods.
