| Abstract: |
| The coating work-pieces were made by laser cladding with the autolytic alloy powder and it's reliability was tested by repeated impact on the fatigue test machine. The sample data was analyzed by MATLAB. The reliability model of laser cladding part under repeated impact load was made. The results show that the fatigue life of laser cladding submits the logarithmic normal distribution. The P-S-N curve is fitted to analyze the relation between the stress of the repeated impact and fatigue life. To provide the foundation of the further reliability analysis, the interface of modeling was designed on the basis of the theory. |
