TiC reinforced composite coating produced by powder feeding laser cladding

The coating of TiC layer on the surface of nickel by electric discharge coating (EDC) with a multi-layer electrode

“…First, laser is used to coat TiC powder on the surface of the workpiece and the coated layer has the surface hardness of HV1200 (Yang et al, 2004). Second, powder (TiC and other elements) is coated on the surface of the workpiece by high-energy electron-beam irradiation to get the surface hardness of HV2060 (Yun et al, 2004).…”

In-situ laser-fabrication and characterization of TiC-containing Ti–Co composite on pure Ti substrate

“…A similar strengthening of the Ti-Co system is sought here by the addition of carbon, since the desired reinforcement phase, TiC, is an extremely hard compound. TiC has previously been used for hard composites such as cermets [26], and also examined for potential Ti implant coatings, where it has shown biocompatibility and osseointegration effect [1,27]. Laser cladding to create surfaces with titanium carbide through the use of TiC particles has been reported [28].…”

Application of spark plasma sintering (SPS) for the fabrication of in situ Ni–TiC nanocomposite clad layer

“…By in situ methods, reinforcements are formed in the matrix through a reaction between elements or compounds, consequently the reinforcement is more compatible with the matrix, and the reinforcement-matrix interface is cleaner [10,11]. This can ensure a sufficient strength of the composite to transfer stresses, by which the problem of interface crack propagation can be avoided [12]. In situ fabrication of TiC reinforced composites has been investigated by a few researchers [10][11][12].…”

“…This can ensure a sufficient strength of the composite to transfer stresses, by which the problem of interface crack propagation can be avoided [12]. In situ fabrication of TiC reinforced composites has been investigated by a few researchers [10][11][12]. Among different fabrication methods MA has been reported as one of the promising processes for the fabrication of in situ TiC reinforced nanocomposites [13,14].…”
