Title:
ELECTRO-DISCHARGE COATED COMPOSITE BODY
Document Type and Number:
Japanese Patent JP2959912
Kind Code:
B2
Abstract:
PURPOSE: To obtain a coated composite body excellent in mechanical strength and thermal shock resistance without deteriorating the function of borides by executing electro-discharge coating using a boride sintered body having a specified componental compsn. contg. binary borides and having high strength as an electrode.
CONSTITUTION: The electrode constituted of, by weight, 40 to 98% of one or more kinds among binary borides expressed by MxBy and 2 to 60% ternary complex borides of one or more kinds among Mo2FeB2, Mo2CoB2, Mo2NiB2, W2FeB2, W2CoB2, W2NiB2, MoCoB, WFeB and WCoB is used; where M denotes Ti, Zr, Ta, Nb, Cr and V as well as x=1 to 2 and y=1 to 4. Then, on a substrate such as steel having sufficient strength, a film having 5 to 300μm thickness is formed by an electro-discharge coating method. In this way, the coated composite body high in mechanical strength and excellent in wear resistance can be obtd. without deteriorating the characteristics of borides such as corrosion resistance, wear resistance and wetting resistance to molten metal.
