| Abstract: | The changing regularity of current and voltage and the producing mechanism of microarc during the microarc oxidation of LY12 alloy were investigated.The results showed that the voltage is one of the main factors during microarc oxidation .The ceramic coating would be destroyed under the condition that voltage was overload .The different electric currents were corresponding to distinct stages.Three distinct stages were observed during microarc oxidation,i.e.The initial stae represents that ceramic coating was produced,the second microarc was aroused and finally the third the steady oxidation stage. |
