SHS Reactive Arc Spray - A New Method to Prepare Multiphase Ceramic Coatings

Abstract:

Ti (C,N)-TiB₂-Al₂O₃ multiphase ceramic coatings were in-situ synthesized on a steel substrate by SHS reactive arc spray technique. The composition and microstructure of the coatings were characterized by X ray diffraction, scanning electron microscopy and energy dispersive spectrometry. The results showed that multiphase ceramic coatings, composed of TiB₂, TiB, TiC_0.3N_0.7, TiN, Al₂O₃ and AlN, can be prepared with the reactive cored wires by SHS reactive arc spray. The coatings exhibit the typical layer microstructure, with discrete second phases distributed in the continuous base phase. The bonding strength between the coating and substrate is 18.9MPa. The micro-hardness and elastic modulus of the coatings are 4.91GPa and 461.4GPa, respectively. The abrasion resistance is 3 times more than that of the substrate.
