    摘要:

    用雙輝等離子技術(shù)結(jié)合空心陰極效應(yīng)將銅鈰元素滲入304不銹鋼。用金相顯微鏡、掃描電鏡、能譜分析儀、X射線衍射儀等方法研究了被滲試樣的組織結(jié)構(gòu)，解釋了滲層分為白亮層和滲層暗帶以及碳元素和鉻元素向滲層表層偏聚以及其他元素分布發(fā)生變化的原因。對(duì)滲后試樣進(jìn)行抗菌實(shí)驗(yàn)。結(jié)果表明，滲后不銹鋼對(duì)大腸桿菌和金黃色葡萄球菌具有良好的抗菌性能。

    Abstract:

    Copper and cerium were metallized into 304 stainless steel by the double glow plasma technique combined with the copper hollow cathode effect. Microstructure of the samples was investigated by metallographic microscope, scanning electron microscopy, energy spectrum analyzer and X-ray diffraction. The reasons why diffusion layers are divided into white layer and dark layer, of the segregation of carbon and chromium to the surface layer and the distribution variation of other elements were explained. Antibacterial experiments show that 304 stainless steel after infiltration has good antibacterial property to E. coli and S. aureus.
