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

The article presents the results of a study of the anti-corrosion properties of composite materials based on epoxy resin modified with a mixture of AGM-9 and TGM-3 in a ratio of 1:3 and treated with zinc oxide nanoparticles. It is established that the coating of metals with epoxy oligomers and zinc nanoparticles significantly increases their resistance to corrosion. After holding in a 3.5% NaCl solution for 90 days, the hardness of metals without coating decreases by 22%, modified with AGM-9 and TGM-3 composites - by 11%, and modified with epoxy oligomers in combination with zinc nanoparticles-by only 3 %.
