Effects of C6H8O7 and C3H8O3 in the Na2SiO3 Electrolyte on Characteristics of Coating Formed on ZAlSi12Cu2Mg1 by Micro-arc Oxidation Kai Lua, Xiangdong Liub, Yaping Zhangc and Wanzhong Gaod School of Materials Science and Engineering, Inner Mongolia University of Technology, Hohhot, Inner Mongolia, 010051, China alk830909@yahoo.com.cn, bliuxd66@126.com, czypnmg@yahoo.com.cn, dclbg@imut.edu.cn Keywords: ZAlSi12Cu2Mg1, micro-arc oxidation, electrolyte, ceramic coating Abstract.
So, the ceramic coating was peeled partly.
The reasons for initial high mass loss may be due to poor bond of ceramic particles in outer layer of the ceramic coatings.

Apart from use as high temperature thermal insulators the new class of materials are also finding use in a variety of products and applications of structural components such as nano-pore high performance coatings, sensors, filters and membranes used in the electronics, aeronautics, space, energy, and biomedical engineering fields.
The International Agency for Research on Cancer has classified glasswool, rockwool, slagwool, and refractory ceramic fibers as "possibly carcinogenic to humans" (Group 2B).
When the larger size envelopes are stacked the density of the material becomes constant and dependent on the stacking sequence of the large ball clusters thus give rise to consistent engineering products. 2(a) 2(b) Figure 2.
