Abstract
Composite coatings of graphite particles codeposited to an electroless Ni-B matrix obtained from the bath using dimethylamine borane (DMAB) as the reducing agent were produced, and the physical properties of the coatings were studied. It was possible to obtain composites containing up to 5.5wt% of graphite particles. The hardness of the coatings decreased with increasing graphite content. Ni-B-graphite composite coatings were found to have good self-lubricating properties and their contact resistance was as low as that of Ni-B coatings.
