The surface of nodular cast iron has been melted and rapidly solidified by Tungsten Inert Gas (TIG) process to produce a chilled structure of high hardness and better erosion resistance. Welding currents of magnitude 100, 150, and 200 A at a constant voltage of 72 have been used to melt the surface of nodular cast iron. Microstructural characterization, hardness measurements, and erosion wear tests have been performed on these modified surfaces as well as on the untreated material.

The effect of surface melting and rapid solidification on the structure and hardness of nodular cast iron has been investigated. Two heat sources were used for surface melting mainly, laser beam (LB) and electric arc generated between the tungsten electrode and the specimen (i.e. TIG). Optical microscope, scanning electron microscope and X-ray diffraction were used to describe the microstructure and identify the phases in the melted zone
