Abstract: The experimental research on
the change of chemical composition and structure of carbide
blade surface treated by laser is carried out, and the relation
between their structure and performance is studied. The result
shows that the element Coexists as a simple substance phase in
primitive sintering structure, while in new melt-sintering
structure it forms a fine alloy phase with original carbide, and
this is the main factor which improves the performance of
carbide blade treated by laser.
Key words:
Laser Carbide blade Simple substance
