Mn-Al MAGNETIC POWDER WITH HIGH CORROSION RESISTANCE AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A Mn-Al magnetic powder and a manufacturing method thereof are provided to obtain high coercive force by evaporating and collecting a Mn-AL alloy through the irradiation of plasma arc.;CONSTITUTION: A forming agent is made by pressurizing material powder including Mn powder of 20 to 60 weight% and Al powder of 40 to 80 weight%. Mn-Al nano powder is collected by irradiating plasma arc to the forming agent and cooling steam. The collected Mn-Al nano powder is thermally treated. The Mn-Al nano powder contains carbon.;COPYRIGHT KIPO 2011
