“…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.

“…FeB phase was not found but Fe 2 B phase exists within the resolution of the XRD pattern. This means the reaction (4) was not completely finished, the remained Fe 2 B phase was also reported in [4][5][6][7]. During the process, TiH 2 and FeB might interact to form some possible compounds such as TiB 2 , TiB or Fe 2 B, etc.…”

“…It is noteworthy that the TiB 2 particle is extremely fine, around 50 nm, in comparison with previous results reported by others. The received TiB 2 particle size was very coarse from several to tens micrometer [2,[4][5][6][7][8]. With coarse FeB particles, TiB 2 was formed firstly on the surface, gradually created network of TiB 2 particles surrounding Fe 2 B core ( Fig.…”

“…The major advantage of in situ process is that the dispersed ceramic phase is created by the chemical reaction between elements of their compounds so that the particles are formed within the metal matrix and are clean, non-oxidized particle-matrix interfaces with higher interfacial strength, improved wettability and better particle-size distribution [3]. The synthesis of TiB 2 phase by various methods have been given: laser cladding [4][5], plasma transferred arc (PTA) [6], aluminothermic reduction [7], and self-propagating high temperature synthesis (SHS) [2,8]. They indicate that TiB 2 particles are able to form in situ via different routes from various initial materials.…”

Phase formation of the composite powder was identified by X-ray diffraction (XRD). The morphology and phase composition were observed and measured by field emission-scanning electron microscopy (FE-SEM) and energy-dispersive X-ray spectroscopy (EDS), respectively. The results showed that TiB 2 particles formed in nanoscale were uniformly distributed in Fe matrix. Fe 2 B phase existed due to an incomplete reaction of Ti and FeB. Effect of milling process and synthesis temperature on the formation of composite were discussed.

“…While nickel, cobalt, iron and titanium based alloys are used as matrix in the production of these composite coatings, in terms of reinforcement elements, hard reinforcement particles such as SiC, TiC, B 4 C, WC, TiB 2 and Cr 3 C 2 are preferred [9][10][11][12][13][14][15][16][17]. Recently, the application of B 4 C in the surface coating pocesses has attracted more and more attentions for its super hardness, thermal stability, high melting point (2450 °C), low density (2.52 g/cm 3 ) and super mechanical properties [18].…”

In this study, wear properties of FeW-B 4 C coatings produced by tungsten inert gas (TIG) process on the AISI 1060 steel were investigated. TIG process was selected because it is a cost-effective approach for melting-based coatings. The treated surfaces were evaluated and characterized by means of scanning electron microscope (SEM), X-ray diffraction analysis, and electron dispersive spectrometry (EDS). The microhardness and wear experiment were also performed by using a microhardness machine and ball-ondisk tribometer. SEM observations showed that the obtained coating had a smooth and uniform surface. According to XRD analysis, borides and carbides phases formed in the coatings. The wear behavior of the coatings was compared with ball-on-disc configuration wear tests, at the same conditions. Average coefficient of friction values of the coatings were obtained at relatively low levels.
