magnesium alloy%viscosity%electrochemical properties
Effects of Ca addition on the microstructure and viscosity as well as electrochemical properties of casting AZ63 magnesium alloy were studied. Testing results show that the viscosity value increases with the increase of calcium content, especially at the higher temperature, and there exists such a relation between the ignition temperature and viscosity of magnesium alloy: when the melt viscosity increases, the ignition temperature increases too. The microstructure of AZ63 magnesium alloy is first refined and then coarsened with the increase of Ca addition. By the addition of 0.15% Ca, AZ63 alloy has more negative open-circuit potential(1. 624 5V), bigger anode efficiency (55.65%) and lower corrosion rate(0.214g/(m2·h).AZ63 allo6y containing some Ca content is a high driving-potential and high-efficiency sacrificial anodes material.
