    摘要:

    摘要：利用等離子表面合金化及輝光轟擊熱擴散復合處理技術在Ti-6Al-4V表面進行銅鉻合金化處理。利用薄膜密貼法對合金層抗菌性能進行測試；同時檢測其耐磨性。通過X射線衍射儀（XRD）、掃描電子顯微鏡（SEM）以及能譜儀（EDS）分析合金層的物相結構、表面形貌以及元素成分分布，并利用三維超景深顯微鏡檢測磨痕深度。結果表明，滲層厚度約為12μm；合金層含銅量約為11%，鉻含量則達13%；銅鉻合金層對大腸桿菌(E. coli)和金黃色葡萄球菌(S. aureus)具有良好的抗菌性能；同時也提高了基材的耐磨性。

    Abstract:

    Abstract: The duplex treatment consisting of plasma surface alloyed with copper followed by thermal diffusion under the bombardment of glow was carried out on Ti-6Al-4V. The antibacterial properties against Gram-negative E.coli ATCC10536 and Gram-positive S.aureus ATCC25923 of the untreated and duplex-treated stainless steel were investigated by using a spread plate method. Meanwhile, the wearing resistance is also tested. The X-Ray Diffraction(XRD)、scanning electron microscope(SEM) and Energy Dispersive Spectrometer(EDS) are exploited in order to observe and analyze the phase structure and the elementary composition of the coats,and the optical microscopy with 3D function is used to detect the wear depth. The results show that the copper concentration on alloyed surface is about 11wt% and the thickness of alloyed layer is about12μm. And alloyed surface exhibits excellent antibacterial properties against both E.coli and S.aureus . And the wearing resistance is improved significantly.
