    Study on additives for nickel–diamond composite electroplating in a sulfamate bath // GUO Wen-xiao, LIU Ping,LIU Xin-kuan*, CHEN Xiao-hong, LI Wei, MA Feng-cang, HE Dai-hua, ZHANG Ke

    Abstract: Ni–diamond composite electroplating was carried out on brass in a sulfamate bath. The effects of diamond amount and the proportion of three additives i.e. FC-001 perfluorocycloalkyl-based nonionic surfactant, didecyldimethylammonium chloride (D1221), and ethylenediaminetetraacetic acid (EDTA) on adhesion strength and porosity of coating were studied by orthogonal test. The optimal bath composition was determined as follows: Ni(NH2SO3)2?7H2O 500-550 g/L,NiCl2?6H2O 10-12 g/L, H3BO3 35-40 g/L, diamond 80 g/L, FC-001 0.15 g/L, D1221 0.2 g/L, and EDTA 1.5 g/L. The coating obtained therefrom had an adhesion strength of 17.305 MPa and a porosity of 0.062 pores per square centimeter. The observation by polarized light microscope and scanning electron microscope showed that the diamonds distributed uniformly in the coating where there are 20 7 47?? diamonds per square centimeter. The process is suitable for making diamond wire saws.

    Keywords: nickel; diamond; composite electroplating; sulfamate; additive; adhesion strength; porosity;orthogonal test
