Effects of thermal plasma jet heat flux characteristics on surface hardening

Pulsed plasma deposition of Fe-C-Cr-W coating on high-Cr-cast iron: Effect of layered morphology and heat treatment on the microstructure and hardness

“…Plasma-assisted treatments belong to the most promising technologies of surface engineering. They can perform synchronous surface modification, strengthening and protective coating deposition on a variety of metallic materials [1][2][3]. Among these methods, the pulsed plasma techniques (PPTs) stand out due to the expanded capabilities of surface property improving arising from additional beneficial factors, such as shock-wave-induced strengthening and radiation stimulated diffusion [4][5][6][7].…”

Increasing efficiency of plasma hardening by local cooling of surface by air with negative temperature

“…The literature devoted to plasma hardening, for example, [1,[3][4][5] does not contain direct indications of the effect of the martensitic interval on the phase-structural composition of the hardened layer.…”

“…In [4], the effect of plasma flows generated by a three-electrode and multi-electrode plasmatron on the surface is studied. It is concluded that the use of multi-electrode plasmatrons is preferable to obtain a higher hardness of the hardened surface.…”

Experimental Definition of Rational Modes of Shock-Acoustic Treatment

“…Для повышения антифрикционных свойств в технологических процессах изготовления деталей предусматривают введение таких операций, как термическая обработка (закалка, отпуск, нормализация). Например, использование углеродистой нормализованной Стали 45 с плазменной закалкой вместо улучшенной конструкционной Стали 40Х не только уменьшает износ деталей и затраты на материалы, но и сокращает технологический процесс [2,3].…”
