论文摘要
等离子体表面冶金/合金是一种表面冶金/合金，用于利用光泽放电产生的低温等离子体，以将合金元件扩散到底物材料表面中以形成合金层。 1930年，德国科学家Bernard Berghuas博士发明的第一个等离子体表面冶金技术是血浆硝化作用。他是第一个应用发光排放以实现表面合金的人。 In order to break the limitation of plasma nitriding technology, which can only be applied to a few non-metallic gaseous elements such as nitrogen, carbon, sulfur, the "Double Glow Discharge Phenomenon"was found in 1978. Based on this phenomenon the "Double Glow Plasma Surface Metallurgy Technology", also known as the "Xu-Tec Process" was invented in 1980. It can utilize any chemical elements in元素周期表，包括固体金属，气体非金属元件及其结合，以实现等离子体表面合金，因此大大扩展了表面合金的领域。在多种材料的表面上生产了无数具有高硬度，耐耐药性和耐腐蚀性的表面合金，例如高速钢，镍基合金和耐燃合金。该技术可能会大大改善金属材料的表面特性，全面提高机械产品的质量，节省许多人类的珍贵合金元素。基于血浆硝化技术，Xu-TEC工艺开发了一个新的“等离子表面冶金”的材料工程领域。这篇评论文章简要介绍了发光放电和表面合金，双光发出现象，基本原理和双光发光等离子体表面冶金/合金的当前状态。还提出了XU-TEC流程的工业应用，优势和未来潜力。
Plasma Surface Metallurgy/Alloying is a kind of surface metallurgy/alloying to employ low temperature plasma produced by glow discharge to diffuse alloying elements into the surface of substrate material to form an alloy layer. The first plasma surface metallurgy technology is plasma nitriding invented by German scientist Dr. Bernard Berghuas in 1930. He was the first person to apply glow discharge to realize the surface alloying. In order to break the limitation of plasma nitriding technology, which can only be applied to a few non-metallic gaseous elements such as nitrogen, carbon, sulfur, the "Double Glow Discharge Phenomenon"was found in 1978. Based on this phenomenon the "Double Glow Plasma Surface Metallurgy Technology", also known as the "Xu-Tec Process" was invented in 1980. It can utilize any chemical elements in the periodic table including solid metallic, gas non-metallic elements and their combination to realize plasma surface alloying, hence greatly expanded the field of surface alloying. Countless surface alloys with high hardness, wear resistance and corrosion resistance, such as high speed steels, nickel base alloys and burn resistant alloys have been produced on the surfaces of a variety of materials. This technology may greatly improve the surface properties of metal materials, comprehensively improve the quality of mechanical products, save a lot of precious alloy elements for human beings. Based on the plasma nitriding technology, the Xu-Tec Process has opened up a new material engineering field of "Plasma Surface Metallurgy". This Review Article briefly presents the history of glow discharge and surface alloying, double glow discharge phenomenon, basic principle and current status of Double Glow Plasma Surface Metallurgy/Alloying. Industrial applications, advantages and future potential of the Xu-Tec process are also presented.
