The results showed that for getting HVOF coating with a high adhesive strength the formation of a solid-liquid two-phase droplet in HVOF process was a necessary condition. Moreover, the high density of WC and W particles in the powder was also in portant.

• 试验表明：喷涂粒子具备液固两相结构是HVOF涂层获得高结合强度的必要条件，而WC与W的高密度是保证HVOF涂层高结合强度的充分条件。
