“…1 had the highest wear loss for all loads. This condition was substantially associated with structure morphology of TiB 2 and increasing the volume fraction of reinforcement phase such as TiB 2 and Fe 2 B in hardfacings [7,9,14,23,26,27,29]. In addition to these results, wear losses increased with the increase in applied loads.…”

“…Although ceramic reinforced light metal matrix (Al, Ti or Mg) composites are being studied intensively, ceramic reinforced ferrous metal matrix composites are also investigated [1][2][3][4][5][6]. With the addition of ceramicbased particles such as carbides and borides into the iron-based matrix, abrasion resistance and material strength increase [7][8][9]. For example, steel matrix composites reinforced with ceramic particles as a protection against wear and corrosion are recommended in chemical and processing industries [10][11][12].…”

In this study, four hardfacings, reinforced with in-situ synthesized TiB2 particles, were cladded by tungsten inert gas (TIG) welding, applying flux-cored wires with varying Fe-Ti and Fe-B content. Microstructural examination, macrohardness and microhardness measurements and abrasive wear tests were performed. Morphology of TiB2 changed from a small-sized hexagonal and rectangular to a coarse plate-like one with the increasing common proportion of titanium and boron. Accordingly, hardness and wear resistance increased linearly with the changing titanium and boron content in hardfacings.K e y w o r d s: TiB2, wear, microstructure, hardfacing, flux-cored wire

“…As mentioned above, the reinforced particles can play a role in protecting the metal matrix in the composite due to their relatively high hardness. Meanwhile, it should be noted that the protection effect is related to the relative position of the matrix metal and reinforced particles and the friction direction [39]. The area behind the particles has a smaller wear loss in contrast to the area in front of the particles along the sliding direction, as shown in Figure 11a.…”

In this paper, a two-step method, rapid-flow mixing followed by high-pressure compositing was used to prepare a macro-ZTA (ZrO2-toughened Al2O3) particles reinforced high chromium cast iron (HCCI) matrix composite. The method is based on the squeeze casting process without general casting pollution problems. The microstructure, mechanical properties and dry sliding wear performance of the fabricated composite were investigated. The results showed that the particles were distributed uniformly throughout the iron matrix and a tightly bonded interface was obtained. Under dry sliding wear conditions, the wear resistance of the composite was significantly improved in comparison with the HCCI alloy, and the relative wear resistance was 1.8 and 2.9 times at the applied load of 300 and 900 N, respectively. When the load increased from 300 N to 900 N, the wear characteristics of the composite changed from shallow and narrow grooves and scratches to damages in the form of fragmentation of particles, transfer layer and interface cracking.

“…In addition, no diffusion is observed of matrix elements (Cu, Mn, and Ni) into the WC particles, which indicates that the WC particles/matrix is clean. Prior work showed that the solubility of the WC particles is limited in copper or copper alloys [12,46,47]. Thus the WC particles retained their initial shape and surface morphology.…”

“…In addition they present high fracture toughness, emanating from the matrix phase. Copper or copper alloy matrix composites have received particular interest for structural applications, notably in wear applications, such as cutting, drilling, and mining tools [7][8][9], electrical contact applications [10,11] and coatings [12]. In particular, copper alloys reinforced with WC particles composites are extensively used as the solid body of drilling bits in the gas, oil and petroleum industries [7,9].…”

In this study, copper alloy matrix composites reinforced with tungsten carbide (WC) particles with the addition of different Ni contents (0, 3, 5, 7, and 10 wt.%) were prepared by the spontaneous infiltration process. Image analysis was used to quantify the microstructural parameters, such as the particle size and distribution, area fraction, binder mean free path, and pore size. The effect of Ni addition on the microstructure, density and hardness are discussed. The results show that a small addition of Ni improves the densification of the infiltrated composites. The highest density value of 11.84 g/cm 3 with a hardness of 327 HV was obtained for the infiltrated composite with the addition of 3 wt.% of Ni. The quantitative analysis results are in good agreement with the microstructure properties and hardness results.
