Method for laser heat treatment of flake graphite grey cast iron surface layer strengthened by chilling

摘要

method of laser heat treatment layer of grey cast iron flake based enhanced by zabielanie, is that the surface of grey iron flake based reinforced by zabielanie overlap coating stopuju0105cu0105 of 0.11 mg / mm2 consisting of the alloy provided and binding, with the stopuju0105cu0105 is si3n4 -? .then the coated surface is subjected to heat treatment by heating with laser power density laser beam 26 / mm2, and the speed of the thrust her e 1.9 mm / s, v.
