초록

The electrodeposition of Ni-Co alloy from a sulfamate bath was investigated. The cobalt content in the Ni-Co deposits is more influenced by the temperature or stirring effect than the current density in the process parameters. As cobalt contents in the Ni-Co deposited layer increased from 0 wt.% up to 43 wt.%, hardness value of the layer rised from 400 Hv up to 700 Hv and crystal orientation (111) increased. However, (200) and crystal size significantly reduced. The tensile and yield strength also increased, while the modulus of elasticity showed the maximum value of $10.4N/mm^2$ at 29 wt.%.
