Abstract
Alloying of the melt with nitrogen in order to improve material properties is well known in steel-making. This effect can also be used in plasma-powder-welding for a distinct improvement of corrosion- and wear-resistance. Using alloys comparable to material numbers 1.4016 and 1.4404 the influence of the process parameters in plasma-powder-welding on the proportion of nitrogen in the cladding is shown. In addition recommendations are made for the regulation of nitrogen concentrations, that are located far above saturation concentration of the alloys mentioned above. With the recommended parameters it was for the first time achieved to succesfully produce claddings with a nitrogen percentage by weight of up to 0.85 at a partial pressure between 0.045 and 0.065 MPa that allow reproducibility.
