【Abstract】 This paper studied the growth principle,microstructure,aluminized depth and the distribution of hardness through different direct electro-heating aluminizing processes of Q235 steel.At the same time,compared it with aluminizing heated by electrical furnace.As the result:the electrical field has an obvious affect on the aluminizing during the heating,and this process can short the aluminizing period and saves energy obviously.更多还原
