Abstract


Boriding is a thermochemical treatment in which boron atoms are diffused into the surface of a workpiece and form borides with the base metal. One basic advantage is that iron boride layers have extremely high hardness values (between 1600 and 2000 HV) [1]. The combination of a high surface hardness and a low surface coefficient of friction of the borided layer also makes a significant contribution in combating the main wear mechanisms: adhesion, tribooxidacion, abrasion, and surface fatigue [2-5]. In this study, the microstructure of the single phase layer (Fe2B) and the double phase layer (FeB + Fe2B) have been investigated at different temperatures by the powder-pack method on the surface of AISI 4150 and AISI M2 steel.
