Effect of chemical regimes on oxide layers of materials in power engineering

Original language description

Nowadays most commonly used materials in power engineering are stainless steels. Temperatures and pressures in systems are currently increased to achieve higher efficiency. In some plants are applied even supercritical values. This paper is focused on improvement of corrosion protection possibilities. Except new materials (titanium, nickel superalloys), different types of surface treatments or layers are used to reduce problems caused by corrosion. If passive film is formed on treated surface, e.g. nitrided, there can appear differences in its properties. The oxide layers are common, however in operation of water-steam cycles in power plants arise problems like exfoliation, bigger porosity or disparity of passive layer. Consequence is larger corrosionrate, which leads up to degradation of the material and failure of equipment. In experimental section were created oxide layers in laboratory conditions and the behavior of materials used in power industry was monitored. Thereafter were e
