Formation and Properties of Nickel–Phosphorus–Graphite Composite Coatings in Autocatalytic Deposition

Resumo

It is shown that nickel–phosphorus–graphite composite coatings can be deposited by the autocatalytic deposition method. The optimal concentration of graphite and the duration of ultrasonic treatment of a graphite suspension in solution for deposition of composite coatings based on the nickel–phosphorus alloy were determined. The influence exerted by thermal treatment parameters on the properties of the deposits was examined. The optimal process conditions are suggested.
