Paper Title:
Laser Fabricated In Situ (Ti,W)C Multi-Ceramics Reinforced Intermetallic Matrix Composite
  Abstract

Using laser cladding technique, Ni3(Si Ti) matrix composite coatings reinforced by in-situ synthesis (Ti,W)C multi-ceramics were fabricatcd by preplacing Ni78Si13Ti9( at%)powders containing different WC contents on the nickel-matrix superalloy substrate. The phases of coatings were investigated by scanning electron microscopy (SEM), X-ray diffractometer (XRD) and electron probe microanalysis (EPMA). Phases of the coatings mainly composed of Ni3(Si Ti), (Ti,W)C multi-ceramics A chemical reaction between WC particle and Ti powder occurs during the laser process, therefore (Ti,W)C was formed.
