摘要：
The paper aims to investigate the influence of the casting conditions and in particular of the mold temperature (T-mold) - as the main parameter of the solidification process - on structure, corrosion resistance and mechanical properties of a Co-Cr-Mo dental alloy. The alloy has been cast at T-mold = 500 and 900 degrees C and the solidification structure has been investigated by using optical and scanning electron microscopy (SEM). Corrosion of the as-cast alloy in two different artificial salivas having pH = 6.0 and 7.7, and mechanical testing revealed that casting Co-Cr-Mo dental alloy at lowest permissible temperature (500 degrees C) does not adversely affect the structure and properties of the alloy. Due to the highest melt solidification rate, an improvement in structure and corrosion resistance while maintaining the mechanical properties was found.
