Mechanical properties of multilayer and multicomponent coatings were investigated in this paper. Titanium nitride/titanium carbide (TiN/TiC-n) multilayer and Ti(C,N) multicomponent coatings were prepared on the surface of AISI H13 hot work tool steel by the pulsed-DC plasma assisted chemical vapor deposition (PACVD). The microhardness, the toughness, the wear loss, and the friction coefficient were examined by Vickers hardness test and the pin-on-disk wear test. The optical microscopy was also used to examine worn surfaces and to characterize wear mechanisms. The results obtaiond show that multilayer coatings of TiN/TiC-10 have the lowest friction coefficient (as 0.2) and wear loss, the highest toughness (as 17. 7 MPa m 1 / 2 × ) and microhardness (as 3150 VHN) among those values for multicomponent Ti(C,N) coatings and other multilayer coatings.

“…This formulation has proven to be useful for the comparison of the wear behavior between different materials [38,39]. Table 2 represents the comparison of wear volume after the wear distance of 1000 m. The wear volume for all coatings was low due to the relatively high hardness of coatings.…”

“…This wear coefficient , with units of m 3 ⋅N −1 ⋅m −1 , has proven to be more useful for the comparison of the wear behavior of different materials than Archard's equation [17,18]. From the wear test result in Table 4, the wear rate of TiC was not dependent on the temperature in the range of 450 ∘ C to 470 ∘ C. Changes in the coefficient of friction of the TiC coating determined during wear measurements are shown in Figure 4.…”

In the PACVD technique, temperature and gas flow rate are two important parameters affecting the coating characteristics. Effect of these parameters on mechanical behaviors of TiC coating that was deposited on hot work tool steel (H13) was investigated in this paper. We analyzed TiC coating composition and structure with grazing incidence X-ray diffraction (GIXRD) and Fourier transformation infrared spectroscopy (FTIR). The mechanical properties of the coatings, such as microhardness, wear resistance, and surface roughness, were studied with Knoop hardness indentation, pin on disk wear tests, and atomic force microscopy, respectively. When the deposition temperature decreased from 490 ∘ C to 450 ∘ C and the CH 4 to TiCl 4 flow rate ratio was also increased from 1.5 to 6, TiC coating color changed from dark gray to silver. The best mechanical properties such as a high hardness (27 GPa), wear resistance, and low surface roughness were related to the coating that was deposited at 450 ∘ C.

“…The absence of Fe ions from the solution may indicate the precipitation of Fe in some form, which would then lead to a higher Fe content in the recovered solids component, relative to Ni. As the pH of the NaCl solution is between 5.3-5.8, which is relatively close to the highly acidic and corrosive pH range [0][1][2][3][4], the possibility of Fe precipitation can be justified [50].…”

“…Therefore, these characteristics offer the potential for TiC-based cermets to replace WC-Co in a variety of industrial applications. For example, it has been shown that TiC-based cermets can exhibit sliding wear resistance comparable to or even exceeding that of WC-Co [3][4][5].…”

A family of TiC-stainless steel ceramic-metal composites, or cermets, has been developed in the present study, using steel grades of 304 L, 316 L, or 410 L as the binder phase. Melt infiltration was used to prepare the cermets, with the steel binder contents varying between 10-30 vol. %. The corrosion behaviour was evaluated using a range of electrochemical techniques in an aqueous solution containing 3.5 wt. % NaCl. The test methods included potentiodynamic, cyclic, and potentiostatic polarisation. The corroded samples were subsequently characterised using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), while the post-corrosion solutions were analysed using inductively coupled plasma optical emission spectroscopy (ICP-OES) to determine the residual ionic and particulate material removed from the cermets during electrochemical testing. It was demonstrated that the corrosion resistance was enhanced through decreasing the steel binder content, which arises due to the preferential dissolution of the binder phase, while the TiC ceramic remains largely unaffected. Increasing corrosion resistance was observed in the sequence TiC-304 L > TiC-316 L > TiC-410 L.
