Abstract
The purpose of this work is to investigate effect of the flame hardening process on hardness and wear rate of ferro casting ductile for permanent mold. The process of flame hardening was carried out by heating the edge of the specimen with an oxy-acetylene flame to temperature of 900 oC, and then followed by quenching process on the edge that was burned. The Vickers hardness testing was carried out on specimens with flame hardening and without flame hardening.The hardness was conducted at five points, namely at a distance of 1 mm, 2 mm, 3 mm, 25 mm and 54 mm from the edge. Wear test was conducted by using Abrasive Wear Test. From the results of hardness and wear test,the hardness of specimens without flame hardening at a distance of 1 mm, 2 mm, 3 mm, 25 mm and 54 mm from the edge were 137.3 VHN, 141.1 VHN, 137.3 VHN, 130.1 VHN and 137.3 VHN, respectively.In the wear test, the weight loss for specimens without flame hardening process was 184.3 mg. While for the specimens that were processed by flame hardening, the hardness obtained at a distance of 1 mm, 2 mm, 3 mm, 25 mm and 54 mm from the edge were 328.8 VHN, 249.7 VHNN, 117.4 VHN, 120.4 VHN and 117.4 VHN, respectively. The weight loss specimen with a flame hardening process was 136.3 mg. There were increasing hardness and wear resistance after flame hardening processes.
