METHOD FOR SURFACE MODIFICATION OF MAGNESIUM ALLOY PLATE

摘要

In the surface treatment of the magnesium alloy plate, crucible contained magnesium oxide, magnesium plates of the specimen is supported an electron gun which is used to vaporize the supports and magnesium oxide to prepare a vacuum chamber having therein. And the internal pressure of the vacuum vessel to about 10 ^-5 and the composition in Torr or less. Then, the composition of the interior temperature of the vacuum chamber to about 200 to about 300 . Then, by supplying oxygen gas into the vacuum chamber pressure 5 10 ^-6 Torr to 1 10 ^{The composition as -4} Torr. Then, the magnesium oxide contained in the gasification furnace through the hot electrons emitted by the electron gun power was added to the magnesium oxide film is deposited on the magnesium alloy plate. So simple, yet can easily be environmental corrosion barrier is not easily formed over a large area.
