Özet

A surface modification process was used to modify the surface properties of a steel material by using the TIC method on AISI 8620 steel with a 135-A constant energy input and the addition of 0.5 g of constant SIC particle and variable C content. SEM and optical microscopy were used to characterize the microstructure of the materials tested. To evaluate the mechanical properties, the microhardness distribution was determined from the surface to the central region. Wear tests were performed under dry friction conditions with WC balls at a 5-N normal load in a ball-on-disk geometry.
