Introduction

Corrosion in liquid cooling loops is caused by chemical, electro-chemical, or abrasive action by the heat transfer fluid on the wetted surfaces. Chemical product layers formed by corrosion can inhibit suitable heat transfer between the liquid and wetted metal surfaces. The corrosive products can introduce debris into the fluid system affecting fluid flow, clogging up filters and tight restrictions, or even damaging pump components. In extreme conditions, leaks can form if enough material is removed from the fluid containment.
