Novel boriding technique of low-carbon steel weldments

Abstract

Abstract Boriding is considered one of the essential surface treatments for carbon steels during the last decades. The conventional methods of boriding are subjected to many limitations due to the sophisticated setup and the time-consuming treatment. Therefore, less complex methods and less time consumption are the main research objectives past couple of years. This research suggests an enhanced boriding surface treatment technique for low carbon steel. The advantages of the proposed method include the reduction of boriding process time through the development of new boron rich compounds which consequently eliminates the need of specially designed furnaces. The illustrated outputs reveal promising results without sacrificing the physical properties. The proposed technique was carried out experimentally. Depth of penetration and microhardness were measured and compared with results from previous literature. Some trials have shown 35 µm depth of penetration of boron layer at 30 min treatment time associated with micro-hardness up to 2388 HV.
