Abstract
The developments in the surface treatment of materials are reviewed. There are several possible forms laser surface treatment can take viz : a) Transformation hardening heating a steel to produce austenite which on the subsequent self quenchin transforms to martensite b) Surface melting simply melting a surface layer c) Surface alloying melting a surface layer and simultaneously changing the composition to achieve the desired properties d) Cladding coating the surface with hard metal particles or with an alloy different from the substrate e) Ceramic coating laser melting, sealing of ceramic coatings f) Amorphous layers coating the surface with an alloy which on cooling solidifies in an amorphous state.
