A gouging type of wear that washes away or grooves out a metals surface is called?

• A. Erosion
• B. Abrasion
• C. Corrosion
• D. Tribowear

Answer: (A)

Erosion best describes this kind of wear because material is removed from the surface by the mechanical action of a moving fluid or by particles carried in the fluid, which can gouge and groove the metal as they strike and wash away material. Abrasion involves direct scraping or grinding by hard particles sliding across the surface, which usually produces scratches rather than grooves formed by fluid flow. Corrosion is a chemical or electrochemical degradation that weakens and dissolves material, not primarily by mechanical washing away. Tribowear isn’t the standard term for this mechanism and doesn’t specifically capture the removal of material by flowing particles.
