利用镍铝二元相图分析了铝含量对制备镍铝合金丝的影响，通过Ｘ射线衍射结果研究了合金丝材及电弧喷涂镍铝合金涂层的相结构，测定了涂层与基体的结合强度，用线扫描测出了涂层与基体间元素的扩散，分析了涂层与基体间造成较高结合强度及形成扩散的原因。
The influence of aluminum content on the preparation of nickel-aluminum alloy wire was analyzed by the binary phase diagram of nickel and aluminum. The phase structure of the alloy wire and the arc-sprayed nickel-aluminum alloy coating was studied by X-ray diffraction. The combination of the coating and the matrix was measured Strength, the elemental diffusion between the coating and the matrix was measured by line scanning, and the reasons for the high bonding strength and the formation of diffusion between the coating and the matrix were analyzed.
