    Microhardness vs. depth diagram of sample No. 6 ( حسب Van-Thuc Nguyen (19469762)

    منشور في 2025
    "…<div><p>This study investigates the effects of arc length, current intensity, travel speed, gas flow rate, and pulse time on surface hardness to better understand the arc quenching of S45C steel with a curved shape. With the standard examination method, increasing the current intensity, Travel speed, and arc length causes the surface hardness to decrease. …"
