The Influence of Heat Treatment Temperature on Diffusion Zone at Siliconized Brass

Abstract

The paper presents the siliconized biphasic brass test results. The thermochemical treatment has been done in a powdery medium with paste, in sealed boxes. The siliconized brass presents high mechanical characteristics and corrosion resistance. After the micro-structural investigations with scanning electronic microscope (SEM) and EDAX analysis, it has established the Si, Zn, and Cu atoms diffusion mechanism in the siliconized superficial zone. At different temperatures of treatment are obtained diffusion zones of various hardness and mechanical properties.
