Abstract:
Absorbing surfaces of solar receivers are coated with black chrome, which provides the surface of steel or aluminum tubes with good absorption properties. However, the chrome coating does not protect well against corrosion because of its high porosity and high internal stresses, which cause a cracking of coatings. [..]

Abstract:
Plasma nitriding applied after a non-conventional treatment in magnetic field to the steel used in industry, have been studied in this paper. It have been demonstrated that the energy of the magnetic field intervenes in the balance of the global power of the phase transformations in solid state altering the thermodynamics, kinetics and the mechanisms of processes, the structures and some properties of the steel.

Abstract:
This paper presents the results of testing the corrosion behaviour of K110 tool steel for cold work in industrial emulsion medium (Lenox Band-Ade semi-synthetic oil + water, in a ratio of 1:10), water and 3.5% NaCl medium. Using the method of electrochemical impedance spectroscopy (EIS) and Tafel extrapolation, electrochemical measurements were performed in order to determine the corrosion parameters. [..]
