Method for laser alloying of the grey cast iron surface layer

摘要

the object of the application is laser modification layer of grey cast iron, in which obrabianu0105 surface layer of grey cast iron is coated stopuju0105cu0105, consisting of layers of stopuju0105cej, made of cobalt powder size particles 2 environment. m and a purity 99.8% and the binder, which is commonly used glass water.then obrabianu0105 surface is subjected to laser heat treatment of stopowaniu with power laser beam for 2.0 - 2.6 kw and the speed of the thrust her 16 - 21 mm / s, with separate heating sometimes work surface equal to 0.18 - 0,25 seconds.
