"Pasivace" povrchu nelegovaných ocelí

Abstract

The objective of this Bachelor Thesis is to explain the terms of construction materials passivity especially of the plain steel and to summarize the most frequent cases of their use. The Thesis introduces the fundamental terms of this issue. The following chapters describe the principles of metal materials corrosion resistance. Further each chapter points out the passivation, which happens due to the lowering of the corrosion resistance, passivation during which the material surface is chemically processed and passivation during which the layer of oxide is formed on the surface of the steel.
