文摘

Combined electric discharge surface alloying (EDSA) and ultrasonic impact treatment (UIT) Combined EDSA + UIT process is effective for the surface quality improvement of low carbon steel. Enhanced corrosion behavior of the steel surface is provided by EDSA alloying with molybdenum. Improved wear resistance is supported by fine precipitates dispersed in α-FeMo solid solution. Subsurface fatigue crack nucleation is caused by UIT-induced compressive residual stresses.
