← TechnologyWhich outcome occurs when a forging press experiences hydraulic fluid contamination?
A)Reduced forging force and precision✓
B)Increased die lifespan due to lubrication
C)Decreased material deformation resistance
D)Enhanced surface finish of forged components
💡 Explanation
The forging force drops because cavitation erosion occurs within the hydraulic pump. Entrained contaminants act as nucleation points, promoting vapor bubble formation and collapse, therefore reducing forging force and precision, rather than enhancing performance as the other options suggest.
