Özet

Boronizing is one of the thermochemical surface treatment processes which is extensively used to obtain excellent mechanical properties such as high strength, very high hardness, good toughness and fracture toughness. In this study, AISI 1050 steel specimens have been subjected to pack boronizing process by using Ekabor 2 powder within the stainless steel seal container. The experiments were carried out at temperatures of 800 degrees C, 850 degrees C and 900 degrees C for 3, 6 and 9 hours to investigate the effect of these parameters on the wear resistance of boronized specimens. Pin-on-Disk wear testing is used to characterize wear properties of boronized specimens. Wear tests were performed at dry conditions under constant load of 30 N by using 220 mesh size Al2O3 abrasive paper. Different rotating speeds of the pin on disk were selected as 300, 600, 900, 1200, 1500 revolutions for each of the test specimens. After the abrasive tests, weight losses of the specimens were measured to determine the abrasive wear resistance of boronized specimens. The results were also compared with unboronized and conventional hardened AISI 1050 steel specimens respectively.
