| Abstract: |
| The aluminum was infiltrated into nickel layer of nickel-coated composite powders via power calorizing,which made it distribute uniformly.The effect of heat treatment temperature,holding time, protective atmosphere,and selected aluminum powders on alumetizing were discussed in detail.The scanning electronic microscope(SEM) was used to observe the morphology of surface of the powders.The experimental results show that selecting ultra fine aluminum powders with less oxygen content and hydrozing could make alu... |
