Magnesium alloy having excellent mechanical properties and corrosion resistance, and method for manufacturing same

摘要: The present invention provides a magnesium alloy having excellent mechanical properties and corrosion resistance, method for manufacturing the same, containing 0.001 parts by weight to 1.0 part of scandium with respect 100 remainder being unavoidable impurities, an increased Fe solid solubility limit decreased corrosiveness. can improve resistance adding which passive state coating formed on surface as well inhibit micro-galvanic between matrix impurities without deterioration properties. Accordingly, be usefully utilized in various fields, such transportation vehicles like automobiles, railways, airplanes, vessels, etc., household appliances, medical devices, daily necessities, etc. reduction biodegradability are required and, particular, field devices implants, stent plate, come into contact body.
