Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
The material processing procedure, which utilizes a high-power density laser, was made to focus on a metal coating to melt the thin layer of the substrate is called Laser Surface Alloying (LSA). It is one of the efficient processes to fabricate material for proper microstructure and non-equilibrium solidification. These fabricated materials have shown good corrosion and wear resistance than the base material of several alloys. Compared to traditional methods like welding, thermal spraying, etc., LSA had the advantage of the constrained heat-affected zone (HAZ), high density, and good mechanical properties. Surface modification using laser alloying of various materials, processing techniques, properties of the alloying surfaces, and combination of multiple alloys and elements to the laser surface modification are described in detail, along with the favorable conditions for adhesive wear.
