The Study of Ti-Al Layered Composite Electrode in the Anti-Gravity Casting Method

Abstract:

The structure and properties of the Ti-Al composite electrode materials prepared by the anti-gravity casting method was analyzed by SEM, EDS, four-probe method and electrochemical workstation. The results show that the metallurgical bonding of Ti and Al can be achieved by the method of anti-gravity casting with the Al temperature800°C, mold temperature of 400°C, pressure difference 0.5MPa. The electrochemical properties of the composite electrode materials is much better than pure Ti anode. Under the same condition,polarization potential of composite materials will fell by 32mV~43mV in polarization potential of pure Ti, it can be increased by 60% or more in current density, the resistivity was only 1/10 of pure Ti.
