영문 초록

There are many plating methods already commercially employed in the surface technology. One of the plating methods is electroless plating, which is deposited by auto-catalytic reduction of metallic ion with the reducing agent in the plating bath. And it has many advantages compared with electrolytic plating in respect of properties of deposit, such as corrosion resistance, wear resistance, hardness, adhesion and so on. In electroless plating of nickel, studies on various factors affecting the plating operation were carrede out. The optimum bath composition and operating conditions were obtained. The structure and properties of the as deposits or deposits after heatment were investigated. T he m ost optimum conditions for the chem ical nickel. N iSO 4; 30g/ℓ N aH2PO 4; 10g/ℓ CH3COONa; 10g/ℓ pH5.0～5.5 temperature; 85～95℃. The plating of electroless nickel deposition showed the maximum on the condition of NiSO4; 30g/ℓ NaH2PO4; 10g/ℓ CH3COONa; 10g/ℓpH5.0 temperature; 95℃ and nickel hardness value followed by heat treatment temperature is maximium in temperature of 400℃. Corrosion resistance of chemical nickel deposits was improved according to increasing of heat treating temperature.
