Abstract:
In this investigation, metal cored wire contains Ferro boron used and hardfaced by FCAW process on mild steel. Chemical analysis test result shows that hardface layer contained of boron element. XRD, OM, SEM, EDX examination test result shows that microstructure of hardface layer consisted of Fe2B+FeB in A+M+Fe2B matrix, macrohardness (RC) test result shows, high value hardness of the deposit layer was gained. In addition wear test result of hardface layer in dry and wet conditions shows that hardface deposited had higher wear resistance in different conditions(dry and wet) than that base metal. moreover study of worn surface with SEM shows that wear mechanism of hardface layer in dry abrasive wear condition was microploughing with less cutting and in wet abrasive wear condition was less microploughing with oxides cutting.
