<P>PROBLEM TO BE SOLVED: To provide a highly reliable, dense laminated member of an amorphous metallic glass layer and a substrate, which is excellent in bonding property and durability. <P>SOLUTION: In the metallic glass laminated member, a metallic glass sprayed coating layer in an amorphous phase is formed on the surface of the substrate using a previously prepared metallic glass in an amorphous phase as a raw material. The metallic glass has a supercooled liquid temperature range ▵Tx of ≥30°C and is composed of a plurality of elements, containing at least one element chosen from Fe, Co, Ni, Ti, Zr, Mg, Cu and Pd as a constituent element. The metallic glass sprayed coating layer has no continuous pore (pinhole) and has a porosity of ≤2%. The metallic glass sprayed coating layer is a dense, homogeneous amorphous phase and is capable of satisfactorily exerting functions of metallic glass, such as corrosion resistance and abrasion resistance. The metallic glass sprayed coating layer is also capable of realizing a large thickness and a large area. Moreover, a metallic glass bulk can be obtained by removing the substrate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
