Stainless steel, a type of steel used for high-temperature parts, may cause damage when exposed to high temperatures, requiring additional coatings. In particular, the Cr2O3 product layer is unstable at 1000oC and higher temperatures; therefore, it is necessary to improve the oxidation resistance. In this study, an aluminide (Fe2Al5 and FeAl3) coating layer was formed on the surface of STS 630 specimens through Al diffusion coatings from 500oC to 700oC for up to 25 h. Because the coating layers of Fe2Al5 and FeAl3 could not withstand temperatures above 1200oC, an Al2O3 coating layer is deposited on the surface through static oxidation treatment at 500oC for 10 h. To confirm the ablation resistance of the resulting coating layer, dynamic flame exposure tests were conducted at 1350oC for 5–15 min. Excellent oxidation resistance is observed in the coated base material beneath the aluminide layer. The conditions of the flame tests and coating are discussed in terms of microstructural variations.

Purpose of this paper is to propose a green campus coexisting in human, nature and culture through making the ecological ly stable campus. The 'green campus' has the six design concepts. These are follows; Vivid campus, Blue campus using the water, Eco-campus aimed at green hand, Cultural campus, Progressive campus and Scholarly campus. These concepts are not only made with the independent role but also the in interactive relation. Campus will be changed into the huge biotope or ceo-garden through the green-hand and water system. Because of the various organism(human, trees, insect etc.), campus will be changed in form of the more vivid space. It should be expected thing this design as following points ; First, it will be improved environmental quality in Kook-Min Univ. changed into the sustainable and environment-friendly green campus as well. Secondly, it will be energetic campus as a living space for rest and cultural activities. ThirdJy, it will be improved the image of campus and opened to the public. FourthJy, it will be grown the talented man who has both a human nature and a intelligence.
