Effect of Traverse Speed on Residual Stress Distribution and Cavitation Erosion Behavior of Arc Sprayed Aluminum Bronze Coatings

摘要

Within the scope of a current research project, arc spraying was used with different traverse speeds to influence the heat transfer and hence the stress state. Microstructural, chemical and mechanical analyses were realized to examine adhesive and cohesive properties. The materials used for spray experiments were the highly cavitation erosion resistant propeller alloys CuAI9Ni5Fe4Mn and CuMn13AI8Fe3Ni2. Analyses of cavitation erosion behavior were carried out to evaluate the suitability for use in marine environments. Finally the residual stress distribution was measured by modified hole-drilling method using ESPI.
