HRTEM showed the formation of  nuclear contact boundary between the shell of the core-shell structure ,in which titanium dioxide and tungsten carbide grain boundaries had a more coherent structure with large area of defects (line defects and point defects), leading to  the distortion in both existing lattice,which was verified through XPS analysis results and the chemical shift of Ti in the formed core-shell structure, suggesting that the interface of WC and TiO2  may be combined in the form of Ti-OW.

Based on the Ñ­»··ü°²·¨²âÊÔ¶Ô¼×´¼µÄµçÑõ»¯ÐÐΪ, it is concluded that µç´ß»¯ÐÔÄÜ of ̼»¯ÎÙ/¶þÑõ»¯îÑÄÉÃ׸´ºÏ²ÄÁÏ with ºË¿Ç½á¹¹ is significantly greater than those without ºË¿Ç½á¹¹. In the two sample which have ºË¿Ç½á¹¹, the one with W/Ti=1:3 has less ̼»¯ÎÙ than the one with W/Ti=1:1. On the other hand, Æä(?)·ÇÕû±È»îÐÔÏàWC1-xµÄµ¥Î»»îÐÔλÊýÒª¶àÓÚWC.
