Abstract
Metal and ceramic bearing means being operated at elevated temperatures of at least 300.degree. C. and higher under atmospheric conditions are effectively lubricated with a novel class of vapor-phase deposited polymer lubricants. The lubricants are formed in situ during bearing operation and can further be applied as a precoat upon at least one of the untreated bearing surfaces for subsequent operation in the same manner.
