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.
The influence of various coatings on the corrosion resistance of the valve stem of shut-off valves has been studied. To assess the quality of the obtained coatings, microhardness, corrosion resistance, deformation-strength and tribological characteristics were determined. Researches have shown that the most optimal way of anticorrosion protection for the shut-off valve stem is chromium-plating, which provides corrosion proofing, increases wear resistance and surface microhardness
