Chromium Coating Developed on Mo-Base Materials Kuang Zi-qi1,DENG chang-guang1,ZHOU Ke-song1,LIU Min1,SONG jin-bing1 (1.Guangzhou research institute of non-ferrous metals,Guangzhou 510651, P.R...., chrome plating on Mo-base materials is very difficult. So we try to make Chrome coating by LPPS. This paper presented Cr coating that is successfully developed on Mo-base materials by controlling......
temperature. Key words: thin films; metals; materials characterization; sol-gel; optical properties; silver 1 Introduction In recent years noble metal nanoparticles have been the subjects of focused researchers due to their unique electronic, optical, mechanical, magnetic and chemical properties which are significantly different from those of bulk materials [1, 2]. It could be attributed to their small......
