With increasing He irradiation flux, the grain size of Ti film decreases and the lattice spacing and width of the X-ray diffraction peak increase due to the He introduction, and the film tends to amorphous phase.

随He引入量的增加，Ti膜的晶粒尺寸减小，He引起的晶体点阵参数和X射线衍射峰宽度增大，晶体的无序程度增加。

The distribution of microhardness is not uniform across the anodic film for the most specimens and the general trend is that the value of the hardness is higher both in the outer film adjacent to the surface and in the inner film near the interface between film and substrate for the specimens with type Ⅱ and type Ⅲ anodizing technology. The measured modulus for anodic film with type Ⅲ anodized is 80.77Gpa. The thermal expansion coefficients of anodic films are measured by two different methods based on X-ray diffraction technique. One way is to detect the lattice spacing change of crystalline phase in powder specimen of anodic film as the increment of temperature by powders of anodic film; and the other way is to determine the thermal stress by entire specimen, that is, the anodic film and the substrate attached together.

利用X射线衍射的方法采用两种不同手段对氧化膜的热膨胀系数进行测试，一种方法为采用氧化膜粉末样品，测量温度变化过程中晶面面间距的改变，进而推出其热膨胀系数；另一种方法为整体试样测试氧化膜中的热应力，通过热应力和热膨胀系数之间的关系计算氧化膜的热膨胀系数。
