摘要：
Laser cladding experiments with a hypoeutectic Stellite 6 alloy have been performed with scanning speeds ranging from conventional values (1.67 mm s(-1)) up to very fast values (167 mm s(-1)). The evolution of the secondary dendrite arm spacing is discussed using the solidification conditions deduced from a two-dimensional heat flux model and the quaternary Co-Cr-C-W phase diagram.
