Disc 적층법에 의한 ZrO_2/Ni계 경사기능재료의 제조에 관한 연구
尹正模,高仁用,朴豊玉 全北大學校 1996 論文集 Vol.42 No.-
Doctor blade is the method for getting the FGM by the steps of making slurry and stacking, drying, de-greasing, pressing sintering method after adding binder, deflocculant, plasticizer as the additives and ethyl alcohol as the solvent to the powder material. In this experiment, a study on the development of manufacture of FGM, we tried to magnify the size of FGM on the basis of spray stacking method, sintering method and powder stacking method.
소결법을 이용한 Si_3N_4, ZrO_2(PSZ)/SUS계 경사기능재료의 제조에 관한 연구

Generally, main problem of heterogeneous materials, composed with metal/ceramics, is wide difference of thermal expansion that exists in layers between metal and ceramics. So new materials are developing, so called FGM(Functionally Gradient Materials), that has relaxation of thermal stress and thermal barrier effect.

Polyarteritis nodosa (PAN) is a disease of small and medium sized muscular arteries, typically involving the skin, kidney, peripheral nerves, muscle and gut. Although its etiology has not been known clearly yet, an immune complex is believed to initiate a vasculitis. Infections, such as hepatitis B virus, hepatitis C virus, and streptococcal infection, may be related with the development of PAN. We experienced a case of PAN preceded by Methicillin resistant staphylococcus aureus-associated otitis media in a 50-year-old woman. This is the first case reported in Korea.
