This literature study is based on the research work conducted in the field of erosion behavior of steel alloys. The focus is on the surface modification of the steel alloys by heat treatment, surface hardening and surface coating methods. Laser cladding and laser hardening processes are also explained. The influence of tribological parameters on the erosion is explained. Steel alloys are chosen because of a wide number of applications due to their excellent properties. Efforts have been made to understand the cause and the remedial action towards the improvements in wear performance. Suitable surface treatment method on the steel alloys may definitely do this work but there should be a need of proper control over the process parameters. The environmental conditions of the laboratory are differing from the real working environment. Hence, the results which are satisfactory at the laboratory are not doing well in real place of application.

In this present investigation, an attempt has been made to study the potential use of plasma sprayed flyash-Al 2 O 3 and flyash-SiC novel composite coatings on Al6061 alloys to mitigate slurry erosive wear. In this Taguchi's L 27 statistical approach, the influence of various process parameters like, slurry concentration, slurry speed, impinging particle size and testing specimen on the slurry erosive wear in slurry with 3.5% NaCl solution were evaluated and analysed. The results obtained indicate that testing specimen and slurry concentration were greatly influencing on slurry erosive wear than slurry speed and particle size. Under all the test conditions studied, flyash-Al 2 O 3 coatings on Al6061 alloy exhibited higher resistance to slurry erosive wear when compared with flyash-SiC coated and uncoated Al6061. Mathematical models were developed by means of regressive analysis to predict the slurry erosive wear of developed composite coatings. This will enable the predictive design of important products with the minimum of wastage and maximum utilisation of sustainable materials using environmentally friendly processes.
