“…In addition, the TiC particles dispersed in steel has very strong capability to capture hydrogen and its isotopes, greatly inhibiting the penetration and diffusion of hydrogen isotopes in the material [14]. Niu et al [15] prepared TiC ceramic coating-reinforced 304 parts using the wire and arc additive manufacturing (WAAM)-laser cladding (LC) hybrid manufacturing technology, and investigated the microstructures and mechanical properties of the 304 WAAM substrate and TiC coating. Results show that a coating with good bonding property and without defects is obtained and the coating has better wear resistance and lower wear rate.…”

Laser cladding technology is a surface modification technology emerging in recent years, and it is widely used in the marine engineering field. Since the structural steels used in marine engineering are mostly carbon steels, their wear resistance and corrosion resistance are poor. In this paper, 316 L stainless steel/TiC composite coatings with different Y2O3 addition amounts were fabricated on Q355B steel surface using the laser cladding technology, and the phase composition, microstructure, microhardness, wear resistance, and corrosion resistance of the coatings were investigated with an X-ray diffractometer (XRD), a scanning electron microscope (SEM), a digital microhardness tester, a friction and wear tester, and an electrochemical workstation. When Y2O3 is added, the crystals in the bottom part of the coating are basically broken and the organisation becomes more dense. When the Y2O3 addition amount is 2%, the hardness is highest, the frictional coefficient curve of the coating exhibits a stable descending trend, and the coating mass loss is the lowest. When Y2O3 is added at 1%, the dynamic potential polarisation curve shows high corrosion potential and low corrosion current density and exhibited the best performance in EIS. The added Y2O3 evidently improves the wear resistance and corrosion resistance of 316 L stainless steel/TiC composite coatings, and this provides a new possibility that a composite coating modified with rare earth oxide is used for repair of marine engineering structures.

“…Moreover, carbides do not interact with liquid sodium at the specified temperatures. At present, TiC coating is well studied, and it is widely applied as a protective material [16][17][18][19][20]. Titanium carbide is also characterized by high resistance to radiation damage that can be beneficial for using it as a protective coating for nuclear applications [21][22][23].…”

This article considers the possibility of using a magnetron-deposited coating for the protection of hafnium hydrides at high temperatures as a material for neutron control rods. We describe the role of TiC coating in the high-temperature behavior of hafnium hydrides in a vacuum. A 1 µm thick TiC coating was deposited through magnetron sputtering on the outer surface of disk HfHx samples, and then in situ X-ray diffraction (XRD) measurements of both the uncoated and TiC-coated HfHx samples were performed using synchrotron radiation (at a wavelength of 1.64 Å) during linear heating, the isothermal stage (700 and 900 °C), and cooling to room temperature. Quadrupole mass spectrometry was used to identify the hydrogen release from the uncoated and TiC-coated hafnium hydride samples during their heating. We found the decomposition of the HfH1.7 phase to HfH1.5 and Hf and following hafnium oxidation after the significant decrease in hydrogen flow in the uncoated HfHx samples. The TiC coating can be used as a protective layer for HfHx under certain conditions (up to 700 °C); however, the fast hydrogen release can occur in the case of a coating failure. This study shows the temperature range for the possible application of TiC coatings for the protection of hafnium hydride from hydrogen release.
