Abstract

In this study, the case properties and diffusion kinetics of Boronized Compacted Graphite Iron were investigated. The experiments conducted at temperatures of 750 ºC, 800 ºC and 850 ºC for 3, 5 and 7 hours. The boride layer was characterized by optical microscopy, X-ray diffraction technique (XRD) and Vickers hardness tester. XRD analysis of boride layers on the surface of the iron revealed the existence of FeB, Fe2B compounds. The thickness of boride layer increases by increasing boronizing time and temperature. The hardness of the boride compounds formed on the surface ranged from 900 to 1450 HV0.10. The activation energies (Q) of Boronized Compacted Graphite Iron was 90.58 kJ/mol. The growth kinetics of the boride layers forming on the Compacted Graphite iron (CGI) and thickness of boride layers were also investigated.
