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

In this paper modified gradient layer was under research, the resulting electrolytic-plasma carbonitriding of low carbon steel 18CrNi3Mo surface was investigated. Aiming to improve the structure and strength properties of the layer, the possibility of application have been shown. Plasma carbonitriding optimized mode is presented as well. Regime of electrolyte plasma carbonitriding which consists in heating the steel sample to 8500C with aggregate exposure at this temperature for 3-7 min. and quenching in cold electrolyte has been optimized. We studied the processes of modified layer structure formation under different conditions
