Functional Characterization of MoCoCrSi/ Flyash Composite Clads Developed on Stainless Steel Through Microwave Hybrid Heating

Stainless steel is one of the chief candidates in most of the engineering and domestic applications. Noticeable resistance to erosion and corrosion, along with good strength makes it suitable for such applications. However, application of the material in harsh environment causes severe deterioration and hence damages the surface, which in turn makes the material inappropriate for its use. The said problem directs us towards surface modification of the candidate material. In the present work, wear/erosion resistance MoCoCrSi/Flyash composite cladding is developed through 2.45 GHz microwaves irradiation by Microwave Hybrid Heating (MHH) technique on functional grade stainless steel. Clad is developed on the surface of the substrate due to fractional dilution of the clad powder and substrate at their interface. The developed clad is characterized for metallographic, mechanical and functional properties. Pin-on—disc test on clads illustrate an evidence of better resistance to wear caused by the contact between clad and the abrasive surface.
