| Summary: | This paper presents the results of a study on thermodiffusion zinc coatings obtained using a technology where zinc dust – waste from hot‑dip galvanizing created during the air blowing of pipes post‑galvanization – is used as the zinc component on steel products, including those with threaded surfaces. The technology involves applying zinc coatings to steel products, including threaded surfaces, through thermodiffusion saturation in a stationary container with a powder mixture consisting of 40 % Znwaste, 59 % Al2O3, and 1 % NH4Cl. This method yields coatings with good appearance, and the desired coating thickness, ensuring compatibility for threading, can be controlled by adjusting the exposure time. |
