| Abstract: | The aluminized layer of 12CrMoV alloy was treated by laser shock processing(LSP) with high power and short pulse.The effects of constituent distribution and microstructure change of aluminized layer of 12CrMoV alloy on its fatigue performance were investigated.The EDS results indicated that 12CrMoV alloy obtained higher thermal stability and aluminized coatings with high-temperature oxidation resistance through aluminizing.However,aluminized coatings have high hardness,low toughness and more roughness,so th... |
