Self-lubricant Ni-CF (S) (Nickel-Graphite fluoride (S)) composite has been coated by electroplating from CF (S) particles suspended in nickel-watt electrolytes.<br>We studied fine CF (S) particle dispersion in the electrolyte and factors controlling the amount of deposited CF (S) in the composite coating.<br>CF (S) particles were dispersed in the electrolyte by adsorbing fluorocarbon cationic surfactants on to particles.<br>Maximum amount of about 4.3wt% CF (S) was deposited in the Ni-CF (S) composite coating at a dispersion concentration of 70g/L. The amount of CF (S) and overpotential decreased linearly with increased nickel ion concentration in that electrolyte and increased temperature.<br>The amount of CF (S) thus appears related to overpotential.
