A wire for out-of-furnace treatment of metallurgical melts comprises a metallic sheath which encloses a core comprising at least one element selected from the group consisting of Ca, Ba, Sr, Mg, Si and Al, wherein at least one layer of a composite coating is applied to an inner and/or outer surface of said sheath, which coating consists of a lacquer paint material and contains high-melting ultrafine particles selected from compounds of metal carbides and/or nitrides and/or carbonitrides and/or silicides and/or borides. The composite coating comprises a protector material, for which ferroalloys and/or flux agents are used. The metals contained in the high-melting compounds are titanium and/or tungsten and/or silicon and/or magnesium and/or niobium and/or vanadium. Said coating is applied evenly onto the surface of the sheath.

A chain component of a chain for transmitting a force includes a steel-based substrate and a hard material layer on an external side of the steel-based substrate. The hard material layer contains metal nitrides and the metal carbide content in the hard material layer decreases toward the external side of the hard material layer.

Proposed is a method of applying a zinc coating to metallic articles by thermal diffusion galvanization. Articles to be treated and a two-component zinc mixture are loaded into a hermetically sealed container, the cavity of the container is filled with an inert gas, and heating is carried out. The first component of the mixture, in the form of a powder of acicular zinc having a size of 3-5 μm, is loaded directly into the container, and the second component, in the form of a powder of spherical zinc having a size of 20-25 μm, is loaded into a capsule having walls which disintegrate at a temperature of 400±20° C., which is placed in the container at the same time as the articles to be treated. A flux is loaded into the container, and an inert process gas and an activating agent for intensifying the adhesion process are supplied.
