✦ Synopsis

&strati

-The effect of the heat treatment of Ti substrate on the service life of Ti-supported 1~0, electrode was investigated in mixed aqueous solutions of H,SO,, (NH,)aS04 and NH,F. The service life was prolonged by the heat treatment ofTi substrate prior to thecoating ofIrOz. Such effect was attributed to the increase in thickness of "HO, layer existing at the Ti/IrO, interface.
