Applications Amorphous-Metal Composite Material, Process for Producing the Same, and Article Obtained by the Same. An amorphous-metal composite material comprises a base and an amorphous metal superposed on and united with a surface of the base. It is obtained by uniting a layer of the amorphous metal to the surface of a base which has been regulated beforehand so as to have elasticity in the same region as that of the amorphous metal. The amorphous metal can thus be stopped from peeling off. Consequently, the mechanical strength of the amorphous metal can be added to the mechanical strength inherent in the base. By regulating the thickness of the amorphous metal, mechanical properties of the amorphous-metal composite material, such as mechanical strength and YoungÕs modulus, can be controlled. The amorphous-metal composite material can be obtained by layer superposition and thermal spraying; this enables even an article of complicated shape to be easily formed. WO 27105738: M. Norio, J. Kawakita, S. Hiromoto, A. Yamamoto, and S. Kuroda. Company: National Institute for Materials Science. Issued/Filed: September 20, 2007/March 13, 2007.

layer, a feeder terminal portion extending from the lower face of the substrate to the internal electrode, and an electrode provided in the feeder terminal portion, wherein the feeder terminal portion and the substrate are fixed to each other by mechanical joining. US 7265962: S. Miyaji, X. Chen, and S. Saito. Company: NHK Spring Co., Ltd. Issued/Filed: September 4, 2007/April 1, 2004. Metal-Impregnated Graphite Composite Tooling. A metallic shell used, for example as a mold, is formed by spray deposition of metallic layers over nonmetallic layers as, for example, a reinforcing fabric. US 7270167: E. Aversenti and A. Solomon. Company: GMIC Corp. Issued/ Filed: September 18, 2007/December 3, 2004. Metal-Sprayed Composite Part. A method of making an article having both a polymeric substrate and a metallic spray deposited layer is presented. The coefficients of thermal expansion of the polymeric substrate and the metallic layer are preferably similar. US 7250194: E. Aversenti and C.P. Covino. Company: GMIC, Corp. Issued/Filed
