中文摘要：

在冷喷洒在倾斜的影响条件下面在底层之上影响的水花粒子的变丑行为用有限元素分析(FEA ) 被调查方法。粒子和底层的变丑上的粒子的发生角度的效果被检验。在在有在一样增加倾斜的角度的底层还原剂的使变形的粒子和底层减少和坑深度之间的接触区域影响速度，这被发现。影响速度的正常部件在结合的影响过程和形成起一个重要作用。

英文摘要：

The deformation behaviour of spray particles impacting upon a substrate under the oblique impact condition in cold spraying was investigated using finite element analysis（FEA） method. The effect of incidence angle of particle on the deformation of particle and substrate was examined. It is found that the contact area between the deformed particle and substrate decreases and the crater depth in the substrate reduces with increasing the tilting angle at the same impact velocity. The normal component of impact velocity takes an important role in the impacting process and formation of bonding.
