| Popis: | A new method for obtaining nitride layers in iron at low temperatures is presented. In this method, bulk iron is coated with a thin layer of nickel and is then treated in an NH3/H2 atmosphere at a temperature of 325°C. Analysis by elastic recoil detection, X-ray diffraction, and Rutherford backscattering spectrometry shows that nitride layers are formed in Fe which is covered with a Ni layer, while uncovered Fe is oxidised by impurities in the gas. The influence of the Ni layer is discussed. It is shown that it is possible to obtain pore free iron nitride layers at low temperatures. |
