В работе исследовано влияние коррозионной среды на снижение сопротивления усталости неупрочненных и упрочненных технологией высокочастотной механической проковкой сварных соединений с угловыми швами.
The paper gives the results of investigation of the influence of corrosive environment on lowering of fatigue resistance of tee welded joints on 10KhSND steel unstrengthened and strengthened by high-frequency mechanical peening (HFMP).
The high effectiveness of application of HFMP technology as a method of surface plastic deformation of metal near the areas of fatigue damage localization to improve corrosion fatigue was established experimentally. Application of HFMP technology improves the cyclic fatigue life of tee welded joints in a corrosive environment 3.5 times and endurance limit
by 80 %.
