Erosion Characteristics of Teflon under Different Operating Conditions

Erosion Characteristics of Teflon under Different Operating Conditions

The present study investigated the solid particle erosion characteristics of Teflon under different impingement angles (15–90°), impact velocities (30–50 m/s), erodent sizes (300–600 μm) and stand-off distances (15–25 mm) at ambient temperature. The Teflon showed ductile erosion behavior exhibited a...
