It is well known that bulk Pd-Ni-P metallic glass with a wide range of compositions (Pd: 25-60 at%; Ni: 20-57 at%; P 16-22 at%) can be prepared. In the present study, we investigated the method of production of electrodeposited Pd-Ni-P metallic glass films whose composition range is the same as that of bulk Pd-Ni-P metallic glass. The composition of electrodeposited Pd-Ni-P films were controlled by adjusting the concentrations of PdCl 2 , NiSO 4 ·6H 2 O and H 3 PO 3 in the Pd-Ni-P bath. X-ray diffraction patterns and transmission electron microscopy images showed that the electrodeposited Pd-Ni-P films were amorphous. The results of differential scanning calorimetry indicated that the electrodeposited Pd-Ni-P films were metallic glass with Pd, Ni, and P compositions of 36-57 at%, 25-43 at%, and 17-20 at%, respectively, which were almost identical to those in bulk Pd-Ni-P metallic glass. Furthermore, we succeeded in producing a Pd 42 Ni 37 P 21 metallic glass film by electrodeposition. The alloy composition of this film was very similar to that of Pd 40 Ni 40 P 20 , which is one of the best bulk metallic glasses because of its glass forming ability (GFA) .
