Effect of bath constitution and internal stresses on the generation of cracks in the electrodeposited Ni--Mo alloys
From symposium on electroplating and 70. event of the European Federation of Corrosion; Budapest, Hungary (7 May 1973). By means of proper composition of the sodium citrate both and adequate cathode current density, crack-free Ni-- Mo coating can be electrodeposited. The effect of current density on internal stress, chemical composition, and critical thickness of the Ni -- Mo deposits are investigated. The stress rises quickly with the increasing molybdenum content in the deposits. The sulfamate bath gives higher current efficiency and larger critical thicknesses than the chloride or sulfate baths. The dependence of crack generation on experimental conditions and on some intrinsic parameters of the deposits is discussed. (auth)
