Corrosion Behavior of Cobalt-Based Stellite 6 Alloy by Combustion Synthesis and Vacuum Induction Melting

Abstract:

Cobalt-based Stellite 6 alloy rely primarily on carbides, forming in the Co matrix and grain boundaries, for their strength and the distribution, size and shape of carbides depend on processing conditions. We have employed microstructure and corrosion behavior of Stellite 6 by combustion synthesis and vacuum induction melting with scanning electron microscopy, electron probe microscopy analysis. The results show that there are significant uniformity on microstructure and corrosion behavior of Stellite 6 by different techniques. The combustion synthesis has more advantages over conventional manufacturing process for Stellite 6.
