Abstract

In the present work, Cr7C3–CrB diffusion layer-coated B4C composite powders were synthesised by a powder immersion method using Cr and B4C powders as reactants. The phase composition and microstructure of treated powders were characterised by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The phase composition and proportion of produced Cr7C3 and CrB varied with the reaction temperatures and composition of the initial powders. After treatment at 800°C, the produced phases were mainly in Cr7C3.After treatment at 1000°C, the produced phases were mainly in CrB. Powder mixtures in which the molar ratio of Cr to B4C was 3:1 and which was treated at 900°C for 4 h were more suitable for the syntheses of Cr7C3–CrB-coated B4C composite powders.
