Effects of the boriding process and of quenching and tempering after boriding on the microstructure, hardness and wear of aisi 5140 steel

An investigation was made on the effects of the boriding process and of quenching and tempering after boriding on the microstructure, hardness and wear of AISI 5140 steel. In this study, a new boriding agent (Baybora®-1) developed for the solid boriding method was used. It was observed that the wear resistance of the borided samples increased by about four times, but the wear resistance of the sample subjected to quenching and tempering after boriding increased by only about two times. Thus, it was determined that quenching and tempering after boriding worsen wear resistance. © 2019 World Scientific Publishing Company

The Effect of Solid Boriding Time on the Structure, Hardness and Corrosion Properties of AISI 5140 Steel

WOS: 000556021800018In this study, AISI 5140 steel samples were borided in an electrical furnace at a temperature of 950 degrees C for 4, 6 and 8 h. Structural examinations, hardness measurement and corrosion tests were performed to determine the effect of the boriding time on the microstructure, hardness and corrosion resistance of the steel surface. It was observed that 4 h of boriding treatment resulted in the forming of Fe2B layer on the surface of the AISI 5140 steel. However, when the boriding time exceeded 4 h, FeB phase formed on the surface layer of the steel in addition to the Fe2B phase. It was also observed that both the thickness and hardness of the boride layer increased with the increasing boriding time. the hardness values of the borided sample surface were approximately seven times greater than unborided AISI 5140 steel. the samples subjected to boriding for 4 h showed higher corrosion resistance than the unboriding steel samples. But boriding time of more than 4 h caused a decrease in the corrosion resistance of the AISI 5140 steel.Scientific Research Project Unit of Krkkale University [2017/079]This study was supported by project code number 2017/079 by the Scientific Research Project Unit of Krkkale University.
