Improved resistance to erosion is usually achieved through increasing substrate ________ using harder alloys, hard facing or face-hardening treatment.

Question

Quizplus · Accepted Answer

Increasing the substrate hardness will improve its resistance to erosion. This can be achieved through the use of harder alloys, hard facing, or face-hardening treatment. Composition and stress may also play a role in erosion resistance, but increasing hardness is the most effective method.
