<P>PROBLEM TO BE SOLVED: To provide a method for producing a rich-durability alloy simultaneously materializing both wear resistance and slidability. <P>SOLUTION: An alloy body 18 is a molding of an alloy having a boron nitride layer formed densely in the surface and more thinly as going inward. The alloy body 18 can be produced by molding or heat-treating an alloy (a raw material) containing boron and metal materials containing one or more kinds of elements in nitrogen atmosphere. Because boron nitride has excellent lubricity and strength, the slidability and the wear resistance can be enhanced by the formation of the boron nitride layer in the surface of the alloy body 18. Furthermore, because boron nitride is integrated (distributed) as a part of the alloy, there is not risk that boron nitride is peeled, and the wear resistance and the slidability can be maintained over a long period. <P>COPYRIGHT: (C)2013,JPO&INPIT |
