Abstract

Boronizing is one of the methods of surface treatment. It is a process by which active boron atoms diffuse into the surface of substrate metal or alloy in order to produce a layer of borides. The process will improve the microstructure and surface hardness of the specimen. In this study, material used is A2 low alloy steel and the boronizing agent used is Ekabor 1 which is normally used in manufacturing industry. This research will cover about boronizing process which is the procedures of the process, method used in this research and the result of the research. The experiment will be done with different times which are 3, 6, and 9 hours and temperature variables 800°C, 850°C and 900°C so that the result can be compared and the best result can be determined. The result of the study will be verified in aspect of microstructure shape, hardness of the specimen and the kinetic of boride layer using Arrhenius equation. Instead of boronizing, deboronizing also considered in this research which is weaken the surface hardness of the specimen.
