Title:
INDUSTRIAL COMPONENT COMPRISING A SILICON EUTECTIC ALLOY AND METHOD OF MAKING THE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2013/096765
Kind Code:
A3
Abstract:
An industrial component comprising a Si eutectic alloy comprises a body having a wear surface, where both the body and the wear surface comprise a eutectic alloy including silicon, one or more metallic elements M, and a eutectic aggregation of a first phase comprising the silicon and a second phase of formula MSi2, where the second phase is a disilicide phase. The wear surface comprises a resistance to erosive wear sufficient to limit transfer of, when an abrasive product is passing thereacross, at least one of the one or more more metallic elements therefrom to the abrasive product, such that the abrasive product comprises an increase in contamination level of 200 parts per billion (ppb) or less of the at least one of the one or more metallic elements M after the passage. The body may also comprise a fracture toughness of at least about 3.2 MPa-m1/2.
