Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Исследовано влияние плазменной закалки на структуру и коррозионную стойкость конструкционной стали 65Г. Методом гравиметрических коррозионных испытаний определяли потери массы до и после термической обработки, площадь коррозионного влияния. Представлены методика эксперимента, расчеты скорости коррозии и анализ полученных результатов. Показано, что плазменная закалка может существенно изменить структуру поверхности и, как следствие, повлиять на устойчивость к коррозии в агрессивных средах. This paper investigates the effect of plasma quenching on the structure and corrosion resistance of 0.65C–1.2Mn structural steel. By the method of gravimetric corrosion tests the mass loss before and after heat treatment and the area of corrosion influence were determined. The experimental methodology, corrosion rate calculations and analysis of the obtained results are presented. It is shown that plasma quenching can significantly change the surface structure and, as a consequence, affect the corrosion resistance in aggressive media.
