In this study, AISI 1050 carbon steel samples were boronized with the powder pack boriding technique at 875°C for 2, 4 and 6 hours using Ekabor 2 boriding powder. The boride layer thicknesses obtained with the boriding time increased and after 2, 4 and 6 hours of boriding, a 30.6, 40.0 and 71.8 µm boride layer, predominantly composed of Fe2B phase, was obtained. Boride layers were formed in tooth-like morphology. Thanks to this boride layer, the surface hardness of the substrate was improved 6.2-6.4 times and a maximum surface hardness of 1543.8 HV was reached. With the Daimler-Benz Rockwell-C adhesion tests, it was determined that the adhesion quality of the boride layer was generally at the HF1 level. With the boriding carried out, the specific wear loss of AISI 1050 steel was reduced from 421.25 mm3/Nm x10-6 to 17.67 mm3/Nm x10-6, and the wear resistance was increased approximately 24 times.
