Abstract

There are many options for metal plating processes to improve the quality of metal and non-metallic materials. Metal coating without the use of electrical energy is known as conversion coating. One form of conversion coating that is widely used in the industrial world is blackening or black oxide coating. One of the determining factors in the blackening process is the cleanliness of the workpiece to be processed, the immersion time, and the heating temperature. So far, heating in the blackening process has only been carried out using an estimate that the heated solution is ready when it boils. Just looking at the boiling solution is not enough to ensure that the heating temperature is in accordance with the provisions. So to get perfect quality results, it is necessary how much temperature will be used for the blackening process. The parameters of this research are to improve the quality of blackening results which are influenced by the length of heating time, heating temperature, workpiece thickness, and workpiece surface gloss. AISI 1015 steel is low-carbon steel. The purpose of this study was to examine the effect of heating time and temperature on the blackening process on the thickness and gloss of the surface layer. The test material in this study was AISI 1015 steel in the form of plates and cylinders in time variations of 50 min, 75 min, and 100 min and with temperature variations of 100 ºC, 150 ºC, and 200 ºC. The results showed that the highest value of the surface layer thickness occurred in the coating with a time of 100 min and in the coating with a temperature of 200 ºC with a thickness of 20.27 μm on the plate workpiece and 20.03 μm on the cylindrical workpiece. Meanwhile, the highest gloss value was obtained for coating with a time of 50 min and a temperature of 200 ºC with a gloss rate of 68.14 GU for plate workpieces and 67.86 GU for cylindrical workpieces.
