ABSTRACT
A series of alloys containing different
amounts of carbides was investigated in order
to obtain better knowledge of the abrasion
resistance for white cast iron. The metallurgical
structure was determined for ten alloys;
three-body abrasion experiments were then
carried out. The abrasion resistance and topographical
parameters were measured systematically
at different stages of the abrasive
process. A relationship between the metallurgical
structure, the abrasion resistance and the
rate of abrasion were clearly established for
molybdenum white cast irons. A mechanism
is proposed for the abrasion process.
