Correlation between Microstructure and Properties of Siliconized Bronzes

Abstract

The study shows some test results about siliconized biphasic tin bronzes. The siliconizing thermochemical treatment has been done in sealed boxes, in a powdery medium with paste. Depending on treatment parameters, different thickness and chemical composition diffusion layers have been obtained. After the microstructural investigations using scanning electronic microscopy and electron probe microanalysis, the Si and Sn atoms diffusion mechanism and the correlation between microstructure of the diffusion layer and properties of siliconized bronzes were established.
