Abstract
The results of the analysis of the structure and properties of the surface layer of aluminum A7 subjected to alloying by the intense pulsed electron beam melting of the film / substrate system. Fold increase in strength and tribological properties of the modified surface layer due to the formation of submicro - nanoscale multiphase structure have been revealed.
Highlights
The possibility of synthesis the nanoscale metastable phases with unique physicochemical and performance characteristics in the surface layer of treated material is the main advantage of the approach based on the formation of surface alloys
The aim of this work is the developing of a method of alloying the surface layer of metals and alloys based on formation and irradiation of the film/substrate system by high-intensity pulsed electron beam submillisecond exposure time
One of the methods is the formation of surface alloys
Summary
The possibility of synthesis the nanoscale metastable phases with unique physicochemical and performance characteristics in the surface layer of treated material is the main advantage of the approach based on the formation of surface alloys. This approach implemented in a number of methods: formation of coatings by electroexplosive method, welding powders using CW laser and compression plasma flows, high dose ion implantation, diffusion saturation in plasma of gas discharges and many others [1,2,3]. Electroexplosive method and welding deposition method leads to the formation of inhomogeneous microstructure, the large grain size and high porosity, due to the high dimensional heterogeneity of the original powder coating and the relatively small rates of the melt quenching [3, 4].
