“…Yoo et all [42] analyzing an abrasive wear of boride steels came to conclusion that alloys with low content of boron (less than 0,6%) had higher wear resistance compared to metals with high content of boron (exceeding 1%). Abrasive wear reduction of steels comprising more content of boron (more than 1%) by FeB fragile phase formation and small quantity of residual austenite [42,43]. While steels with low content of boron are characterized with greater wear resistance connected with austenite availability in the matrix structure.…”

The microstructure evolution, mechanical properties, and tribological properties of deposited metal Fe-C-Cr-Ti-B alloy by self-shielded flux-cored wire electrode (FCAW-S) with the introduction of exothermic addition and without it are investigated. Experimental studies showed that the introduction of CuO -Al exothermic addition in the composition of the wire core filler reduced the grain size of the deposited metal. Furthermore, X-ray diffraction analyses show that the boride layer contained FeB, Fe2B, and Ti(C, N) phases. Depth-sensing indentation was used to determine hard phase properties (hardness, Young's modulus and plasticity coefficient). It was shown that introduction of CuO -Al exothermic addition in the core filer increased the mechanical properties of deposited metal. The latter can be explained by the grain size decrease, as well as a change in the phase composition of the deposited metal due to additional copper alloying. This transformation is accompanied by an increase in hardness and in the Young's modulus. Tribological tests showed the effectiveness of introduction of the exothermic addition CuO -Al into the filler core for increasing the wear resistance under conditions of 3-body abrasive particle wear.

“…In addition, it must be noted that one type of boride (FeB and Fe 2 B) did not exist on the surface of the borided DI at elevated temperatures. Thus, the acceleration of the process of wear under an abrasive loading at elevated temperatures can be related to the presence of cracks induced by internal stresses in the interphase of a double phase layer due to significant differences between expansion coefficients at both phases (Motallebzadeh et al, 2015).…”

“…Resistance to softening at elevated temperatures is another important property of borided surfaces (Li et al, 2008;Sen et al, 2004b). In a recent study, the effect of volume fraction of FeB (V FeB ) on the wear resistance of dual-phase (consisted of FeB layer on Fe 2 B layer) boride layers formed on 31CrMoV9 and X40CrMoV5-1 quality steels have been examined at room and elevated temperatures (Motallebzadeh et al, 2015). Although the examined borided steels exhibited superior wear resistance and identical friction characteristics at room temperature, their wear resistances decreased at 500°C in association with cracking at the contact region.…”

“…The borided 31CrMoV9 steel (V FeB = 31%) underwent severe wear at 500 °C under dry sliding conditions against an alumina ball when compared to the borided X40CrMoV5-1 steel (V FeB = 47%). Since the dry sliding wear response of the boride layer at high temperatures is related to the control of thermal stress by altering the structure of the surface layers [10], it is necessary to study the wear behavior of boride layer identified for components exposed to abrasive elements and high operating temperatures. In the present work, the focus is on the characterization of the microstructure and the study of abrasive wear features of the untreated and pack borided DI under various working temperatures.…”

ABSTRACTIn this study, GGG 50 quality as-cast ductile iron samples were pack borided in Ekabor II powder at 900 °C for 3 h, followed by furnace cooling. Structural characterization was made by an Optical Microscopy (OM). Mechanical characterization was made by hardness and pin on disc wear test. Pin on disc test was conducted on a 240-mesh Al 2 O 3 abrasive paper at various temperatures in between 25 and 450 °C. Room temperature abrasive wear resistance of the borided ductile iron increased with increasing its surface hardness. High temperature abrasive wear resistances of the borided ductile iron linearly decreased with increasing test temperature. However, the untreated ductile iron exhibited relatively high resistance to abrasion at a temperature of 150 °C. Above 150 °C, the untreated ductile iron exhibited similar abrasive wear performance as compared to the borided ductile iron.

The effects of the addition of small amounts of Ti on the phase constitution, microstructure, and wear resistance of Fe-B-C hypereutectic overlays produced using powder-wire composite arc welding were investigated. The Fe-B-C hypereutectic overlay phase consisted of TiB 2 and TiC in addition to Fe and Fe 2 B with the addition of Ti. The addition of Ti inhibited growth of the Fe 2 B and Fe 3 (C,B) phases. When the Ti content reached 0.918 mass%, the daisy-like Fe 3 (C,B) phases disappeared, and precipitation of dispersed TiB 2 and TiC began, which improved the wear resistance. Overlays without macroscopic cracks could be obtained. The wear mode of the Fe-B-C hypereutectic overlay changed from a mixture of microcutting and microfracture wear to microcutting wear.
