Abstract

A coating has been done using the FeAl intermetallic alloy deposited onto the surface of the substrate with the Flame Spray technique using N2 and O2 as a gas booster. The launching of Low Carbon Steel substrates with FeAl intermetallic alloys using N2 and O2 gas boosters, characterizes the results of Low Carbon Steel substrate coatings using OM and XRD, examines the use of N2 and O2 as gas boosters on Fe-Al coatings on Low Carbon Steel substrates. The stages of this research are starting from the preparation of Low Carbon Steel substrate, then coating the FeAl intermetallic through Flame Spray technique, XRD and OM characterization of Low Carbon Steel coated with FeAl intermetallic alloy, and finally doing a performance comparison between O2 and N2 gas as a booster gas. From the results of Optical Microstructure obtained an average thickness of the coating on the Low Carbon Steel substrate before oxidation with O2 booster gas is better than the other substrate that is equal to 414.18 μm. After the oxidation process, the average gap between the Low Carbon Steel substrate attached to the FeAl intermetallic alloy with N2 as a gas booster is better than other substrates which is 114.26 μm. On the curve that can be seen the mass is shown below. Low Carbon Steel supported by FeAl intermetallic alloy with N2 as a gas booster is better than other substrates. In XRD characterization, Low Carbon Steel substrate which chooses with FeAl intermetallic alloy with N 2 as a gas booster is better than other substrates which are characterized by the formation of more FeAl phase compared to Fe-O phase namely Fe 5 Al 8 dan Fe 1.5 Al 0.5 , and this substrate is increasingly questioned for the safety well .
