摘　　要：为研究低温等离子体对青铜器粉状锈的影响作用,本文采用二氧化碳、氧气、氨气和氮气等四种气氛,开展了不同氛围、不同参数下低温等离子体对碱式氯化铜的稳定化作用实验,采用超景深显微镜、激光拉曼光谱仪和水分吸附仪等对处理前后实验样块进行了物化性能分析。结果表明,经氮气氛围下射频等离子体处理后,实验样块外观颜色变化明显,表面结构变得较为致密,吸湿性降低了26%,起到了减缓水分侵蚀的作用。In order to study the effect of low temperature plasma on powdery rust of bronze ware,this paper uses four atmospheres such as Carbon dioxide,Oxygen,Ammonia and Nitrogen to carry out the stabilization treatment experiment of Basic copper chloride by low temperature plasma under different atmospheres and parameters.The physical and chemical properties of the samples treated before and after were analyzed by means of Ultra-depth of field microscope,Laman spectrometer and Water adsorption instrument.The results showed that the appearance color of the samples changed obviously after the RF plasma treatment in nitrogen atmosphere,at the same time the surface structure of the samples became more denser,and the moisture absorption of the samples was reduced by 26%,which played a role in reducing water erosion.
