Thick DLC, multi-layered DLC, high adhesion type DLC and low arching type DLC were deposited on magnesium alloy, AZ80, and fatigue tests were performed in air and 3% NaCl solution. It was found that both multi-layered and low arching deposition played important roll to improve fatigue strengths under corrosive environment. Subsequently, WC-12Co was thermally sprayed between DLC film and substrate as an interlayer. The hybrid coating could well improve both wear-resistance and fatigue strength. The optimal thickness of an interlayer was proposed based on the fatigue tests.

在镁合金AZ 80表面沉积了厚膜类金刚石膜、多层膜类金刚石膜、高附着力类金刚石膜和低附着力类金刚石膜，并在空气和3%NaCl溶液中进行了疲劳试验。结果表明，多层和低渗镀层对提高腐蚀环境下的疲劳强度起着重要作用。随后，WC-12 Co作为中间层热喷涂在DLC膜和基体之间。该复合涂层能很好地提高耐磨性和疲劳强度。在疲劳试验的基础上，提出了中间层的最佳厚度。
