Laser Surface Melting (LSM) has the potential to increase the resistance of steels to erosion-corrosion. In this study a submerged jet impingement system containing a brine under saturated CO2 conditions with sand has been used to assess the effect of LSM on the erosion-corrosion resistance of X65 steel. Erosion-corrosion rates under different experimental conditions were deduced based on CFD-simulated results and surface profile measurements. Scanning Electron Microscopy (SEM) was used to observe the morphology of erosion-corrosion damage. The results show that the erosion-corrosion rates at various impact angles can be decreased by LSM. Changes in microstructure, corrosion behaviour and hardness of X65 steel induced by laser treatment were analyzed by using optical microscopy, Transmission Electron Microscopy (TEM), Energy Dispersive X Ray analysis (EDX) together with electrochemical polarization and hardness distribution measurements, in order to clarify how laser treatment imparts the effects on the steel.

“…In this process increases the hardness of the base metal 3-fold increase in hardness was obtained with a maximum case depth of 0.45 and 0.65 mm at respective laser powers of 1.3 and 1.5 kW. A 2-fold increase in wear resistance was observed for the laserhardened steel [30].Laser hardening of steel or cast-iron components can yield 20% greater hardness than conventional heattreating. The efficiency of aluminium hardening by radiation from a CW Nd:YAG laser was found to be considerably higher than in the case of a CW-CO2 laser [31].…”

An overview is given on the state of art of the laser based surface processing of engineering materials. In major engineering application surface of the material plays a major role. since the surface has the direct contact with the environment as well as the load. The different parameters such as hardness, toughness, wear resistance etc on the surface has to be enhanced based on the application, hence there is a need to go for surface processing. Conventional surface processing has its own limitations toward recently developed materials and other functional aspects. These aspects can be overcome by laser based surface processing. In this paper an attempt has been made to investigate the principal and effect of laser interaction on materials such as heating, surface melting, vaporization, plasma formation , ablation etc .The different types of laser based surface processing of engineering materials based on their properties, Processing parameters and functional aspects which is considered for different application has been discussed.

“…Hence, it is very much essential to modify the surface of the components to improve the service life of the component. Wear, corrosion and tear of the component surface are the main reason for the failure of the engineering materials [1][2][3][4]. It is comprehensively not verbalized in potential wear applications.…”

Abstract. Small and large scale (gas power plant, hydro power plant), automobile industries are suffering by failure of component. Sometimes, it is also observed that the component which was failed due to these reasons are very much costly and replacement of those also very difficult due to the complex geometry. By using Microwave hybrid heating, WC-12Co based clads were developed on austenitic stainless steel (SS304). Microwave clads were developed by introducing the preplaced, preheated powder for a duration of 15 min to microwave radiation at 2.45GHz frequency and 900 W power in domestic microwave applicator. By using optical microscope and scanning electron microscope (SEM), the developed clads were characterized. By using pin-on-disk, wear performance of the WC-12Co based clads and unclad samples were tested. It is observed that developed clad samples performed superior wear resistance than unclad samples.
