“…The Fe-Mn-Si alloy with additions of Fe-B and B4C has also presented an increase in the average hardness of the samples, and the higher values presented by the B 4 C alloy can be attributed to the higher concentration of Fe-B phase observed in DRX. Despite the hardness increase, the values were inferior than those observed by [4,7], due to the lower addition of boron used in this study.…”

The aim of this work is study the effect of the FeB and B4C addition on the microstructure and cavitation resistance of the plasma PTA Fe-Mn-Si coating. The hardness of the iron-based alloy can be increased by adding a certain amount of carbides, such as B4C and Fe-B, leading to formation of secondary phases of high hardness. Three alloys Fe-Mn-Si with B4C and FeB additions were deposited by plasma transferred arc process in AISI 304 plates. The microstructure and dilution were analyzed by optical microscope and scanning electronic microscope. Mechanical properties were analyzed by microhardness and cavitation resistance was analyzed by ultrasonic ASTM G32 indirect method. It was found thus far that the addition of boron either by adding Fe-B, such as by adding B4C caused an increase in the wettability of the alloy and consequently better deposition. We also observed a significant change in microstructure, forming higher levels of secondary phases and the formation of a hipoeutetic structure. There was also an increase of the hardness of coatings deposited with addition of boron. It was observed an increase on the cavitation resistance of the coating with FeB and B4C addition

“…In situ Fe-TiB 2 composites have been fabricated using various methods, such as laser cladding [2,3], plasma transferred arc (PTA) [4,5], aluminothermic reduction [6], spark plasma sintering (SPS) [7], and self-propagating high-temperature synthesis (SHS) [8][9][10][11]. In our previous work [12], Fe-TiB 2 powder was synthesized in situ from an iron boride (FeB) and titanium hydride (TiH 2 ) powder mixture by planetary ball-milling and subsequent heat treatment.…”

The in situ formation of TiB 2 particulates via an interface reaction between Ti and FeB powders was studied. The effects of mechanical activation by high-energy milling on the decomposition of TiH 2 and the interface reactions between Ti and FeB powders to form TiB 2 were investigated. Powder mixtures were fabricated using planetary ball-milling under various milling conditions. The specific ball-milling energy was calculated from the measured electrical power consumption during milling process. High specific milling energy (152.6 kJ/g) resulted in a size reduction and homogeneous dispersion of constituent powders. This resulted in a decrease in the decomposition temperature of TiH 2 and an increase in the formation reaction of TiB 2 particulates in the Fe matrix, resulting in a homogeneous microstructure of nanoscale TiB 2 evenly distributed within the Fe matrix. In contrast, the powder mixture milled with low specific milling energy (36.5 kJ/g) showed an inhomogeneous microstructure composed of relatively large Fe-Fe 2 B particles surrounded by a thin layer of Fe-TiB 2 within a finely dispersed Fe-TiB 2 matrix region.

“…4 These ceramic particles improve the wear resistance of welding coatings. 16,17 SiC dispersed in the AISI 316L stainless steel has also been used to improve the wear resistance. Several techniques, such as gas tungsten arc welding (GTAW), 18 plasma transferred arc welding (PTAW), 19 laser cladding, 20 electric spark deposition (ESD) 21 and shielded metal arc welding (SMAW), 22 are used for the surface modification of the hard faces of metal powders.…”

Composite powders including Ti, B4C and Stellite 6 were deposited on the 316 stainless steel using plasma-transferred arc welding to improve the wear resistance. Microstructural characterisation using an optical microscope and a Vickers hardness tester was performed on the surface to determine the coating and hardness. Scanning electron microscopy and energy-dispersive-spectroscopy line scanning were also applied to characterise the microstructure, the chemical composition and the process of wear. Results showed that Ti, B4C and Stellite 6 considerably affected the microstructure and morphology of the coating. The in-situ new phases, namely, TiC and TiB, remarkably improved the wear resistance compared with the Stellite 6 coating only.Avtorji so kompozitne prahove iz zlitine Stellite 6, Ti in B4C nana{ali na povr{ino preizku{ancev s plazemskim napr{evanjem (PTAW), da bi izbolj{ali njihovo odpornost proti obrabi. Izvedli so mikrostrukturno in mehansko karakterizacijo povr{ine z uporabo opti~nega mikroskopa in Vickersovega merilnika trdote. Prav tako so izvedli preiskave z vrsti~nim elektronskim mikroskopom (SEM) in linijsko energijsko disperzijsko spektroskopijo (EDS), da bi ugotovili mikrostrukturo, kemijsko sestavo in potek obrabe. Rezultati raziskav so pokazali, da so Ti, B4C in Stellite 6 znatno vplivali na mikrostrukturo in morfologijo prevleke. In-situ sinteza novih faz (TiC in TiB) med plazenskim napr{evanjem kompozitnih prahov je mo~no izbolj{ala odpornost prevlek proti obrabi v primerjavi s prevlekami, izdelanimi samo iz prahu Stellita 6. Klju~ne besede: in-situ sinteza novih faz, mikrostruktura, PTAW (plazemsko napr{evanje), odpornost proti obrabi
