Abstract
Diamond pressing (DP) is a finishing treatment method that is used to create necessary parts with certain roughness. It is used to impart certain physical and mechanical properties, such as appearance, corrosion, friction, wear and fatigue resistance. In this work, the influence of diamond pressing process (DPP) on corrosion resistance in A53 steel was studied in HCl solution. Microhardness (MH), microstructure, weight loss and potentiostatic polarization were investigated at pressing forces of 40, 60, 80 and 100Â N. Microhardness increases with increasing the applied force to a certain limit (i.e. â¼90Â N). The percentage improvements were found to be 30, 17, 13, and â9% for 40, 60, 80 and 100Â N pressing forces, respectively. Weight losses decrease with increasing the pressing forces up to 90Â N. Corrosion potential and corrosion current decrease with increasing the pressing force reaching a minimum at about 90Â N and then begin to increase with increasing the pressing force. Occasionally, high forces caused failure in the microstructure when the prising force exceeded 90Â N. Percentage protection against corrosion shows a supporting behaviour.
