There are many heaves and concaves which can be observed on the surface of the layer, and so they make the surface of the layer rough. The surface of the layer is rich in Ti, but gradually the Ti decreases. It shows that The combine of the layer with the base is good, which result from the heat diffusing and chemical metallurgy reaction.

涂层表面由许多凸起和凹坑组成，表面稍粗糙，这是脉冲放电的工艺特点决定；涂层内部Ti元素由表层至与基体界面处呈梯度分布，并且Ti元素也渗入基体一定深度，说明结合良好，为冶金反应和热扩散的结果。
