Magnesium alloy electric wheel hub micro-arc oxidation production research

Most electric vehicles at home and abroad is configured to aluminum alloy wheel hub, its quality, energy saving, shock absorption, noise reduction and vehicle dynamics characteristics index is much lower than magnesium alloys. Magnesium alloy is 30% lighter than aluminum alloy, the damping effect is 30 times that of aluminum alloy. Replace the aluminum alloy with magnesium alloy wheel hub, driving the development of magnesium alloy material development and deep processing technology, to reduce electric vehicle weight and power consumption, energy conservation and environmental protection; To reduce vibration and noise; Improve ride comfort and electric vehicle dynamic characteristics such as objective (transportation quality each reduce 10%, energy consumption will be reduced 8% ~ 10%). But its corrosion resistance is poor, seriously limits the application. Commonly used chemical oxidation and anode oxidation formation of oxide film on magnesium alloy has certain protective effect, but its corrosion resistance, environmental friendliness, appearance is not satisfactory, be badly in need of the development of new surface treatment. In recent years, people trying to develop a variety of new technologies, such as micro arc oxidation technology, the better

One Micro-arc oxidation mechanism

Micro-arc oxidation technology is a new surface treatment technology of green environmental protection, can grow in light metal surface in situ ceramic layer directly. Its technological characteristics, surface treatment, as well as the performance of the since the technology was invented by the favour of people, its mechanism is to light metals such as aluminum, magnesium, titanium and its alloy put in electrolyte aqueous solution as anode, using the method of electrochemical spark discharge spots on the surface of the material, the thermal chemistry, plasma chemistry and electrochemistry, under the joint action of metal oxide ceramic layers of a surface modification technology

Two research methods and technology

This topic in the research on magnesium alloy electric wheel hub, higher requirements on the toughness of the alloy, so choose AM60B, melt and initial temperature of 468 ℃, the melting end temperature is 596 ℃, the liquidus temperature range of 165 ℃. The chemical composition as shown in table 1.
