Cemented Chromium Carbide

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1960
Cr2O3とカーボンブラックよりCr23C6,Cr7C3,Cr3C2を製造し,その製造条件を調べ,これら各種炭化クロムとNiとの焼結体を製造し,その焼結体の機械的性質の測定,X線解析,耐酸化試験,耐食試験を行なった。その結果,Cr7C3-Ni系焼結合金は焼結不完全で,X線解析の結果,焼結体中の炭化物相は単純なCr7C3でないことがわかった。Cr3C2-15%Ni焼結合金にCr7C3を10%まで加えた場合,機械的性質,常温におけるH2SO4,HCl,NHO3,NaOHに対する耐食性には,Cr3C2-15%Ni焼結合金と著しい差は認められなかった。耐酸化性についてはCr3C2-15%Ni焼結合金が,これにCr7C3を10%加えたものまりもすぐれた耐酸化性を有することが明らかになった。各種耐食試験 ...
