Effect of the structure and properties of scale on the quality of surfaces in hot pressure treatment of metal

We have developed a complex method for studying the formation of scale that makes it possible to investigate this process on any grade of steel under various heating parameters.
The elevated content of alloying elements (Cr, Ni, Cu, Si) and the diminished content of carbon in alloy steel (as compared to carbon steel) is the reason behind the appearance of a zone of intergrain oxidation on the surface of the metal.
By increasing the coefficient of air excess we can make the conditions of scale formation and separation in alloy and carbon steels comparable.
