摘要
Ni-Mn alloy has been prepared on a rotary cylinder cathode by mechanical electrodeposition process. The experimental results showed that the deposited Ni-Mn layers present compact and fine-grained granular microstructure and smooth surface with distinct abrasion marks. The manganese content increased with current density and Mn-sulphamate concentration in solution. The as-deposited Ni-Mn had a tensile strength of over 1,100MPa. When the manganese content was above 0.4wt%, the tensile strength of annealed Ni-Mn became higher than the as-deposited one after 2-hour anneal at 250 degrees C. The thermal stability mechanism was discussed by analyzing the dimple fracture appearances.
