“…This measurement proves that Ti diffuses from TiC. The formed intermetallic phase is most likely TiC in iron-containing matrix materials [17,18]. Figure 6 shows metallographic images of the investigated samples around the DZ2 diffusion zone (transition between the two coatings) after V2A pickling.…”

“…This measurement proves that Ti diffuses from TiC. The formed intermetallic phase is most likely TiC in iron-containing matrix materials [17,18]. Further SEM and light microscopy studies showed that transcrystalline fracture through the carbide crystal the WC-containing coatings led to the dissolution of the WC into the matrix material (Figure 8a).…”

Gray cast iron (GJL) is known for its excellent damping property and high thermal conductivity, thanks to its unique lamellar graphite and pearlite structure. In a recent study, laser metal deposition (LMD) was explored as a potential process to enhance the corrosion resistance and wear mechanism of this tribological system. The focus was on laser cladding of gray cast iron using two different of stainless-steel materials, namely 430L and 316L, combined with TiC and WC particles. To create the samples, a multilayer coating system was employed. A comparative analysis of the microstructures was performed to understand the interaction of the laser beam with the material (composite materials). Surface properties were then characterized using light microscopy and electron microscopy (SEM) before and after subjecting the samples to a shock corrosion test, simulating automotive conditions. Additionally, phase analyses were performed at the interfaces between the coatings and the substrate, with particular attention given to the behavior of the graphite lamellae at these interfaces. This study aims to provide valuable insights into the potential improvements that can be achieved through laser cladding on gray cast iron, specifically in terms of corrosion resistance and wear mechanisms. By analyzing the microstructures and surface properties, researchers can gain a better understanding of the performance and durability of the coated samples.

“…However, the presence of a solid solution of carbon inside the Ti coating cannot completely be excluded, even if it is present in a very tiny amount. On the other hand, FeTi and TiC are the most probable phases in points 6 and 7, as suggested by C-Fe-Ti isothermal section at 1000 °C [19,20]. However, the exact determination of the nature and stoichiometry of the formed phases would require finer analyses, which are out the scope of the present paper.…”

“…Titanium was chosen because it is a carbideforming element [18] and it has a melting point of 1668 • C, making its use suitable for sintering a wide variety of metals and metallic alloys. Some authors report that the C-Fe-Ti ternary system is not in favour of the formation of the cementite Fe 3 C [19,20]. Moreover, titanium is a better electrical conductor than graphite.…”

Spark plasma sintering technique is used for the fabrication of dense materials with a fine-grained microstructure. In this process, a powder is placed into a graphite mold and a uniaxial pressure is applied by two graphite punches. A graphite foil is inserted between the punches and the powder and between the mold and the powder to ensure good electrical, physical and thermal contact. One of the major drawbacks during sintering of metal powders is the carburization of the powder in contact with the graphite foils. In this study, a PVD coating of titanium was applied on the graphite foils in contact with the metal powder (pure iron). The results are promising, as the investigations show that the application of a Ti PVD film of 1.5 and 1.1 µm thickness is effective to completely avoid the carburization of iron powder. Carbon diffuses inside the PVD film during sintering. In parallel, iron diffusion was revealed inside the Ti coating of 1.5 µm thickness. On the other hand, a Ti PVD film of 0.5 µm thickness provides a protection against carbon diffusion just on the sides in contact with the mold, proving that the coating thickness represents an important parameter to consider.
