Advances in surface engineering

Abstract

Surface engineering has become essential to improve the surface properties of materials. Surface engineering involves the design of surface and substrate system to give a cost effective performance enhancement which the substrate is incapable to achieve. Various surface modification methods have been dealt with. Advanced methods of surface modification such as plasma spray methods, ion beams based techniques and laser surface modifications have been dealt in detail with the examples of achieving better corrosion, oxidation and wear properties of several iron base low alloy steels. Application to heat exchanger tubes in power plants and special austenitic alloys for aggressive environment has been discussed.
