Question 39

When connected to a more anodic material, titanium may suffer severe __________.

    Correct Answer: A

    When connected to a more anodic material, titanium may suffer severe corrosion. This is because, in such a galvanic couple, titanium, being the more cathodic material, will prompt the anodic material to corrode itself and protect the titanium. However, if titanium becomes the anodic material due to an unfavorable environment or conditions, it will undergo accelerated corrosion.
