The corrosion phenomenon in wheel mold during low pressure die casting process was investigated with optical microscope and scanning electron microscope. The results show that the surface of mold cavity reacts with high-temperature aluminum liquid after coating falling off, which results in soldering in the mold surface. Then, the transition layer is formed and it composes of Fe-Al-Si intermetallic compound. Finally, after the cyclic action of high-temperature aluminum liquid, the transition layer continuously diffuses and falls off from the mold surface, and it eventually causes corrosion of the mold.

When selecting a die casting mold for aluminum components, one of the most important decisions is choosing between high-pressure die casting (HPDC) and low-pressure die casting (LPDC) processes. Both methods utilize reusable steel molds but differ significantly in pressure, filling dynamics, cycle t Read More
