An antibacterial article with long-lasting antibacterial effect is provided. The antibacterial article includes a substrate, a base layer formed on the substrate, a plurality of NiCrN layers and a plurality of Cu-Ce alloy layers formed on the base layer. Each one of the NiCrN layers and each one of the Cu-Ce alloy layers are deposited on each other. The NiCrN layer can lead the Cu ions and Ce ions release slowly. So the antibacterial article has long-lasting antibacterial effect. A method for making the antibacterial article is also provided.本發明提供一種具有持久抗菌效果的抗菌鍍膜件,其包括基材、形成於基材表面的打底層,該抗菌鍍膜件還包括形成於打底層表面的複數鎳鉻氮層和複數銅鈰合金層,該複數鎳鉻氮層和複數銅鈰合金層交替排布。本發明所述抗菌鍍膜件利用鎳鉻氮層疏鬆多孔的結構,使銅鈰合金層的部分嵌入到該鎳鉻氮層中,對銅鈰合金層中銅和鈰離子的快即溶出起到阻礙作用,從而可緩釋銅和鈰離子的溶出,使銅鈰合金層具有長效的抗菌效果。此外,本發明還提供一種所述抗菌鍍膜件的製備方法。10‧‧‧抗菌鍍膜件11‧‧‧基材13‧‧‧打底層15‧‧‧鎳鉻氮層17‧‧‧銅鈰合金層
