“…Futhermore, the compressive residual stresses and microrelief on the surface are formed after the UIT process. In comparison with the LHT+SPD, the preliminary SPD before the laser [15] or plasma [16] treatment allows preparing the structure for high-temperature processing, increasing the depth and microhardness of the hardened layer compared to the separate thermal treatment.…”

Досліджено вплив режимів зміцнюючої комбінова-ної обробки на зміну властивостей поверхневого шару конструкційної сталі. Показано, що товщина зміц-неного шару становить 0,18-0,69 мм при поверхне-вій твердості 10,5-12,5 ГПа. Отримано математичні моделі та номограми товщини зміцненого шару і твер-дості сталі залежно від технологічних параметрів комбінованої обробки. Знайдені залежності дозволя-ють визначати конкретні умови зміцнюючої обробки Ключові слова: конструкційна сталь, поверхневе зміцнення, комбінована обробка, лазерна обробка, азо-тування, товщина шару, твердість Исследовано влияние режимов упрочняющей комби-нированной обработки на изменение свойств поверх-ностного слоя конструкционной стали.

The possibility of using ultrasonic surface hardening with implementing the indenter tangential oscillations to the deformed surface to improve the quality of the detail surface layer produced from low carbon steel and ferrous alloys is considered in the paper. The mathematical description of the trajectory of the relative displacement of the instrument and the detail is presented. It is established that the important technological parameter influencing the character of the formed micro-geometry is the angle between the instrument vectors and the detail speed. The effect of the technological factors of the ultrasonic surface hardening on the amplitude and spacing parameters of the surface roughness are revealed. The results of the research showed that the ultrasonic processing at the tangential oscillations of the indenter allows forming a stable micro-geometrical state of the surface layer with low values of the amplitude and spacing parameters on the details made from non-ferrous alloys and low carbon steels.
