Zink and Zn-Al for coatings

Use

The Zink powder and its alloys are used to protect apparatuses, containers, reservoirs, pools, pipes, heat exchangers, bridges, hydraulic structures, power-industry equipment, vessel hulls, and other metallic structures from continuous and pitting corrosion. Powder ddischarge rate while spraying onto metallic surfaces when creating a coating with a thickness of 200 microns is approximately 1.7-1.8 kg/m². Handheld gas-fired torches or mechanized apparatuses are used for deposition.

A reliable method for protecting metallic structures made from carbonic and low-alloy steels from corrosion is to apply coatings of Zn-Al alloy to their surfaces. Thermal Zn-Al coating applied using AP-ZnAl16 powder effectively protects structures and equipment used in the atmosphere and in fresh- and saltwater. The servicable life of the coating depends on the thickness of layers applied and can reach several decades.
