Laser cladding in-situ carbide particle reinforced Fe-based composite coatings with rare earth oxide addition WU Chaofeng1,ZHANG Weiming1,LIU Wenjin1,ZHANG hongjun1,ZHONG Minlin1,MA Mingxing1... matrix composite (PR-MMC) has excellent properties such as good wear resistance, corrosion resis-tance and high temperature properties. Laser cladding is usually used to form PR-MMC on metal surface......
material close to the surface and the rapid self-quenching provided by the bulk of the material results in the formation of martensite[10]. The hardness values also show that the laser cladding layers...-y axis CNC gantry table. Cladding tracks were formed by moving the specimen relative to the beam in the x-direction. During deposition, the substrate displacement speed under the laser beam was 500......

Faculty... impossible by conventional processes. The application of pulse shaping in laser cladding with wire to avoid the solidification problems in relevant steel is demonstrated. The results show that sound......
University of Technology, Beijing 100124, China Received 15 October 2018; accepted 19 April 2019 Abstract: To avoid high crack sensitivity of TiB-Ti composite coating during laser cladding process, network-like structure composite coating was fabricated with laser in-situ technique on titanium alloy using 5 μm TiB2 powder as the cladding material. The microstructure, phase structure and properties......
