Abstract

Niobium films were grown by DC magnetron sputtering on CrNi3Mo steel substrates. Its microstructures and mechanical properties were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM) and conventional probes. The results show that the negative bias voltages significantly affect its surface morphology and its mechanical properties. For example, at a bias of 150 V, the compact film has the highest erosion-resistance.
