A study is made on the abrasion resistance of (Ni P) diamond composite coating By adopting such technological conditions as pH value of 4 5 and temperature of 80 ℃ and capacity of 8～10 m 2·m -3 and by moderately adding diamond pretreating in specified way,a (Ni P) diamond composite coating with excellent abrasion resistance can be obtained.The abrasion resistance of (Ni P) diamond composite coating obtained from diamond with roughened and hydrophilic pretreatment is better than that obtained from diamondwith activated and hydrophilic prelreatment;and moreover,excellent(Ni P) diamond composite coating can be obtained by slightly adding to plating solution the diamond with roughened and hydrophilic pretreatment.The abrasion resistance of (Ni P) diamond composite coating is more than fifty times of that of steel No.45 after heat treatment.
