材料的生物污损给海洋工程造成了巨大的损失，防护涂料是解决这一问题的一种方法。本文采用离子镀技术制备了TiSiN/Ag多层膜。在涂层中制备了不连续的Ag层，以保持涂层优异的力学性能。在微观上，观察到银离子通过“微通道”从涂层中释放出来，并在海水环境中表现出抗菌活性。发现释放速率由涂层的微观结构决定。为了延长涂层的使用寿命，期望银离子释放浓度能够接近最小抑菌浓度（MIC）。在本工作中，TiSiN/Ag多层涂层可以在相当低的浓度下释放Ag离子，并保持其优异的杀菌活性。这为制备长效抗菌超硬涂层提供了新的思路。
Biofouling of materials has caused significant loss to marine engineering and protective coatings have served as a solution. In this work, the TiSiN/Ag multilayer coatings synthesized by ion plating were investigated. Discontinuous Ag layers in the coating was prepared to keep excellent mechanical properties of the coating. In microcosmic, it was observed that Ag ions released from the coating by ‘micro-channel’ and expressed anti-bacterial activity in seawater environment. The released rate is found to be determined by the microstructure of the coating. In order to prolong the service life of the coating, it is expected that the Ag ions release concentration can approach the minimal inhibitory concentration (MIC). In this work, the TiSiN/Ag multilayer coating can release Ag ions at a pretty low concentration and maintain its excellent biocidal activity. This work has provided a new thought to synthesize a long-lasting anti-bacterial and superhard coating.
