| Abstract: |
In this work the use of nickel and nickel alloys (Inconel) as coating materials for cold spraying was investigated and analyzed. For this purpose the coatings mechanical and physical properties were examined. The target was to qualify and optimize the coating materials used for serial and single item production regarding characteristics, reproducibility, process safety and efficiency. The applied coatings were analyzed considering the applied spray parameters using shear test, adhesive tensile test, hardness test, porosity measurement, deposition efficiency and micro sections. Furthermore, a correlation was performed between the shear resistance and the adhesive tensile strength of the applied layers. Component regeneration and protective layers against mechanical and chemical stress,e.g. wear and/or corrosion, are fields of application. The materials used have a large potential for use in industry, e. g. for high temperature components of turbines or power plants.
