Abstract

Nano crystalline Ni-Co-B alloy thin films were deposited on the copper substrate at different temperature by electrode position method. Electro deposited Ni-Co-B thin films were subjected to the structural, mechanical and magnetic characterization analysis. The chemical composition of the coated films was analysed by EDAX. The surface and structural morphology of the coated film were analysed by using SEM and XRD. The mechanical properties of Ni-Co-B films have been studied by VHT. The magnetic properties of thin films have been analysed by VSM. The electroplated NiCoB thin films were strongly adherent to the copper substrate The SEM pictures of Ni-Co-B thin films shows that, the deposits of thin films are crack free, uniform and bright surface with fine grain size. All the electro deposited Ni-Co-B films exhibit FCC crystalline structure with crystalline size in the order of Nano scale. The VSM result of Ni-Co-B thin films shows that the Ni-Co-B thin films coated at high bath temperature have highest saturation magnetisation value with lower coactivity. Due to highest magnetisation value with low coactivity, Ni-Co-B thin films can be used for the manufacturing of MEMS and NEMS devices.
