The surface appear-ance of Tm-Ni-Co alloy films was silver smooth and adhesive. The surfaces of Tm-Ni-Co alloy films observed by scanningelectron microscope (SEM) were uniform, adhesive and compact. The sizes of metallic grains were about 80-100nm,100-200nm, 50-60nm, and 90-120nm at 1mV·s^(-1), 5mV·s^(-1), 10mV·s^(-1) and 50mV·s^(-1), respectively. The Tm-Ni-Co alloy film wasamorphous as proven by the X-ray diffraction(XRD). 展开更多
