Title:
METHOD FOR MODIFICATION OF CEMENTED CARBIDES AND CEMENTED CARBIDES MODIFIED BY THE METHOD
Document Type and Number:
WIPO Patent Application WO/2011/019041
Kind Code:
A1
Abstract:
Provided are a method for the modification of cemented carbides and cemented carbides modified by the method, and more particularly, an advantageous method for modifying a cemented carbide layer which has been formed by thermal spraying on the surface of a metal substrate. The method for the modification of cemented carbides includes applying friction stir processing to a cemented carbide to refine the grains of the binder phase contained in the cemented carbide. In particular, effective modification can be attained by applying friction stir processing to a cemented carbide layer which has been formed by thermal spraying on the surface of a metal substrate.
