Abstract: An anti-friction composition creating a protective coating between two moving metal parts under high pressure and the resultant high temperatures, for example, the valve train of an internal combustion engine. The composition includes basically a liquid mixture of organometallic compounds, such as a bismuth/organic carrier liquid component and a tin/organic carrier liquid component. The liquid organometallic compounds hold the bismuth and tin metals until they atomically dissociate under high pressure and/or temperature conditions, releasing the bismuth and tin metal atoms and/or molecules. These raised atoms and/or molecules form an alloy that protectively coats the machinery metal surfaces, greatly reducing friction and wear.
