Titanium sandwich panels with cellular cores of a uniform 1–5 mm diameter open cell size are well suited for impact energy absorption and cross flow heat exchange applications.









Adjacent to TiC cermet, a continuous Ni-rich layer is found at the interface between the interlayer and TiC cermet substrate. The multilayer granular structure of Ti–Al system and TiC are found in the reaction products. It is noted that void is inevitable in the reaction products and the density is enhanced with the increase of joining pressure.



The development of sub-micron TiC cermet from elemental powders was carried out in two steps: (a) mixing and mechanical activation of reactants. (b) Reactive sintering by SPS. Ferrotitanium with 72 wt%Ti (mean particle size less than 45 µm) and purity (99%) of amorphous carbon black (mean particle size of 0.5 µm) were used as raw …







Fig. 3 shows the back-scattered electron image and major element content distributions (along the line indicated in the electron image) of TiC cermet/steel joint brazed with Ag–31Cu–23Zn braze alloy foil at 850 °C for 15 min. It can be seen from the image that there are three zones between the TiC cermet and the steel. For the sake of …



TiAl alloys were joined to TiC cermets using combustion synthesis method. The Ti-C-Ni metallic powder compact acted as a joining interlayer in the joining process. The identification and mechanisms of the reaction at the interface and interlayer were investigated. From the analysis of the microstructure of TiAl/TiC cermet joint, it is noted …















The emergence of the Ni2SnTi intermetallic compound significantly enhances wettability with the Cu alloy. Consequently, this leads to a reduction in porosity and crack defects within the TiC–Cu cermet, resulting in an increase in its hardness. By adding Ni, the Hv30 of the TiC cermet (with a D50 of 10.2 μm) increases from 402.4 to …



ABSTRACT: The TiC-Ni (Mo) cermet composite coating was prepared on 7 A52 aluminum alloy by the Self-propagating High-temperature Synthesis (SHS). The microstructure and properties of coating were investigated by means of SEM, EDS, XRD, micro-hardness test and bonding strength test. The results showed that: the coating consisted of TiC ceramic ...





TiC-40NiCr cermet exhibited lower wear rate compared to TiC-25NiCr when tested against Al 2 O 3 at room temperature. However, at 400̊ C, TiC-25NiCr cermet coating showed superior resistance to sliding wear, while the TiC-40NiCr cermet coating experienced abrasion, resulting in the formation of severe grooves and adhesive tearing.





4. Conclusion. TiC–ferritic FeCr (AISI 430L) steel binder-based cermet has been successfully fabricated through an additive manufacturing process such as SLM with the application of the pulse shaping technique. Fabrication of brittle materials such as cermet can be made effective using the pulse shaping technique.



Abstract. The tribological behaviours of TiC-based cermet coatings, prepared by electrical discharge coating (EDC) using a semi-sintered TiC tool electrode, have been investigated. The as-deposited coatings exhibited complex microstructures, comprising TiC grains within an Fe matrix, on both high speed steel (HSS) and 304 …



Here's the best way to solve it. Estimate the maximum expected thermal conductivity for a Cermet that contains 65 vol% titanium carbide (TiC) particles in a cobalt matrix. Assume thermal conductivities of 27 and 69 W/m-K for TiC and Co respectively. Recall that I said in class that the rules of mixtures often applies to other properties ...





Results of an experimental study of physical properties, microstructure, and phase composition of a TiC–NiCr cermet compact obtained by hot pressing are presented. It is shown that an increase in the volume fraction of carbide inclusions is accompanied by an increase in hardness HRA (from 25 to 55) and microhardness HV300 (from 350 to …
