Formation of surface layer during complex laser boriding of carbon steels and properties thereof

摘要

The main parameters of the laser action zones(microhardness, depth, tribotecknical characteristics, alloying elements distribution) at laser boriding of the carbon steels by refractory compounds-based powder composites with high boron contain have been investigated. The possibility of the effectivity increase of the alloying elements masstransfer into the melting Metal pool by means of inclusion into the powder composite composition of the surface active Element has been shown.
