Investigation on Fe310 steel of a drilled surface after cryogenic treatment

This study aims to assess the internal surface properties of drilled hole made in Fe310 steel plate after cryogenic treatment. The objective is to understand how cryogenic treatment, which involves exposing the material to extremely low temperatures, can enhance the mechanical properties and wear resistance of Fe310 steel. The wear characteristics of the materials are determined through a wear test, considering variables such as slurry particles, rotational speed, slurry temperature, and duration of cryogenic treatment. The wear test is performed using a vacuum cavitation system with a power output of 1000W, an adjustable pump suction rate, and a duration set at 60mins. Fe310 steel specimens are used in the experimental procedure to conduct wear test. The data collected is then analyzed using SPSS (Statistical Tools for the Social Sciences) software. The cryogenic treatment process involves cooling the specimens to sub-zero temperatures and maintaining them for a specific duration. Experimental and numerical results are utilized to evaluate the wear rate model, examining the impact of cryogenic treatment and other factors on the wear of Fe310 mild steel surfaces. The model predicts and illustrates the wear behavior of the inner surface, indicating an improvement. From the experiments, more speed and cryogenic time promotes to decrease in wear rate, as well more abrasive content and temperature causes more wear. The wear rate of the cryogenic heat-treated Fe310 mild steel drilled hole surface is 833.33mg/min-mm$^2$.
