Abstract: The present invention relates to a process for obtaining an intermetallic compound having magnetic properties, added to a base lubricant to reduce friction between metal surfaces and reduce wear of diverse types of equipment prolonging the working life thereof. The intermetallic compound of the present invention is formed by pulverised nanometric substantially-spherical particles having an extremely active surface, capable of forming a thin adherent film when applied to a metal surface, conferring protection against frictional movements produced by contact between metals. Said intermetallic compound is a new additive for addition to a base lubricating oil, conferring high performance on such oil.
