The present study has been undertaken, keeping in view the importance of corrosion problems in underground mine-wire-ropes and their impact on economy and safety of mine working. Mine-rope-wire specimens of different chemical composition and percentage deformations were obtained from Usha-Martin-Black, Ranchi. Mine water was collected from the coal-fields of Jharia-Raniganj belt. It was observed that the determination of the surface could be minimized by optimization of the carbon content and percentage deformation of the mine-rope-wires. Stress relieving of the mine-rope-wires at 100 degree C, followed by electro deposition of metal metalloid Ni-P-D, micro crystalline alloy, produced a surface with low corrosion rate and high hardness value. Incorporation of benzylamine inhibitor was found to reduce the corrosion of mine-rope-wires further. Corrosion of the rope-wire specimens, in both inorganic and organic acids, appeared to be proportional to the deformation stress to which the material was subjected to during manufacture. The spalling mechanism was observed to control the average corrosion behaviour of these materials, for a long term exposure condition. Improvement of bulk material had been considered to improve the adhesion between the substrate and the corrosion crust film. The crack propagation susceptibility values of the deteriorated rope-wires, given by I/D, d/L was found to be critical at 0.3 below which it was less hazardous (D = diameter of rope-wire; d = depth of crack; L = length of crack).
