Thermal Interference Fit Anode Assembly for Cathodic Protection

Abstract

A mounting bolt and sacrificial anode assembly is provided. The zinc anode is cylindrical while the mounting bolt is made from aluminum alloy and is machine threaded with an anodized bolt head resting on an anodized bolt head shoulder having two faces with one face being non-anodized. For assembly, the anode is heated to a uniform temperature of approximately two hundred degrees Fahrenheit and the mounting bolt is cooled to approximately zero degrees Fahrenheit after a minimum of six hours and preferably twenty-four hours. The anode is then hand pressed onto the mounting bolt to bottom out on the non-anodized face in order to form a single fused assembly.
