Friction and wear behavior of Micro-arc Oxidation Ceramic Coating On Pure Magnesium Surfaces Fei Chen1, a, Hai Zhou1,b ,Fanxiu Lv2,c 1Enginerring Education Center, Beijing Institute of Petro-chemical Technology, Beijing 102617, China 2School of Materials Science and Engineering, University of Science and Technology, Beijing 100083, China achenfei@bipt.edu.cn, bzhouhai@bipt.edu.cn, cfxlu@mater.ustb.edu.cn Keywords: pure magnesium ; microarc oxidation; tribological behavior Abstract.
Now it has been widely applied in various industries like auto, electron, aviation, and spaceflight as well as civil industries [1, 2].
Ceramic has become the third generation of engineering materials to follow steel and aluminum for its special physical and chemical features, but its poor property in hardness and machinability limit its application.
Through microarc oxidation, in-situ-grown ceramic coating is directly formed on the surface of magnesium alloy, which makes the perfect combination of the second or third generation of engineering materials possible [3, 4].

Comparing Tests on the Durability of Concrete after Long-term Immersion in Different Salt Solution Xiaoping Su1, a, Li Zhang1, b 1 School of Civil Engineering, Changchun Institute of Technology, Changchun, Jilin, 130012, China asxp5400@163.com, bzl60158@sina.com Key words: salt; immersion; concrete; durability Abstract.
The concrete structures in such environment are often corroded by all kinds of soluble salt, which has become a serious threat to the durability and safety of concrete engineering.
In order to study the damage degree and characteristic of concrete under the condition of the soluble salts erosion, the way of salt immersion was chosen to imitate the situation that concrete engineering is corroded by the dissolved salts in the saline soil or groundwater or saline water.
