Tribological Features of Self-Lubricated Coatings Obtained by Atmospheric Plasma Spraying (APS)

This study analyzes the tribological behavior of nickel-graphite and aluminum-silicon-polyester thermal sprayed coatings and the effect of non-metallic compounds. Self-lubricating coating composites based on a metallic matrix with ceramic or polymeric filler phases show potential applications requiring high wear resistance and thermal stability at low cost. In some cases, the nickel-graphite layer may eliminate the need for external lubricants or lubricating systems. Paper includes a German-language abstract.
