Paper Title:
Erosion Behavior of TiC-xNi Composite Coatings In Situ Synthesized by Electro-Thermal Explosion Ultra-High Speed Spraying
  Abstract

With aim to investigate the effect of the content of Ni on erosion behavior of the TiC-xNi coating at elevated temperatures, The TiC-xNi (x=0, 5, 10, 15 , 20wt.%) composite coatings were in-situ synthesized on nickel-based alloy substrate by the self-developed electro-thermal explosion ultra-high speed spraying (EEUSS) device with the cored wire. Erosion properties of the coatings were assessed by the erosion tester under 90° incidence angle and 650°C. X-ray diffraction (XRD) and microhardness tester were used to investigate the coating phases and microhardness. The coatings consisted of TiC phase and Ni binder phase, as well as the residual C. The microhardness of TiC-xNi coating with the Ni content from 5 wt.% to 20wt.% decreased with the increase of the content of Ni. Elevated temperature erosion test indicate that the spiculate quartz particles impact the surface of the coating which lead to the loss of material. The erosion resistance of the TiC-xNi coatings increased first and decreased afterwards with the increase of the content of Ni. The relative erosion resistance of coating with 10 wt.% Ni addition is excellent which is about 2 times than that of TiC-20Ni coating under 650°C and 90° incidence angle.
