GX300CrMo27 samples which were reinforced by Ti-B as 1-2.5 wt% have been produced. The first three samples for each samples
were heat treated at 1000 oC. The specimens’ heat treatment time have been changing between 1, 3 and 6 h. The last sample was not
heat treated for comparison. The abrasive wear tests which have loads of 10, 20 and 30 N was performed to the samples to determine
the abrasive wear characteristic. In addition, SEM images of all samples were taken to examine the effect of reinforcement and heat
treatment on the carbide morphology

In this investigation, a gas tungsten arc welding (GTAW) is used as a high energy density beam to form a coated surface over 0.15% C carbon steel with FeB, FeTi and graphite powders. The microstructure, microhardness and dry-sliding wear behavior of the composite coating were investigated by using optical micrograph (OM), X-ray diffraction (XRD), scanning electron micrograph (SEM), energy dispersive X-ray analysis (EDS), microhardness tester and adhesive wear tester. A lot of types of carbide and borides were formed. The shape of the graphite present in the FeBFeTi-C composite TIG welding coatings is various from sheet-like to triangle. Within the wear test conditions used in the present research, on Fe2B coated samples wear was essentially oxidative until the failure of the coating.
