<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for degreasing magnesium alloy or a member containing magnesium alloy which provide safe degreasing of the magnesium alloy by means of a heat treatment step alone. <P>SOLUTION: The apparatus and method for degreasing are characterized in that: the inside of a closed type heat treatment furnace 1 is regulated to a superheated steam atmosphere of prescribed temperature while shutting off the inflow of outside air, then an object to be treated 13 is fed to the inside of the heat treatment furnace 1, the object to be treated 13 being composed of magnesium alloy having an adhering substance 13a adhered thereto or a member containing this magnesium alloy; and the object to be treated 13 is exposed to the superheated steam atmosphere inside the heat treatment furnace 1 and separated into soot 33a and solids 33b while being kept noncontact with outside air. Thus, the magnesium alloy can be safely degreased in a non-oxidized state. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
