Abstract: PURPOSE:To produce a composite material having low porosity and excellent mechanical properties by subjecting a W wire to plasma spraying of a base material consisting of an FeCrAlY alloy in an inert atmosphere under a relatively low pressure then subjecting the same to a heat treatment in a vacuum at an adequate temp. CONSTITUTION:The W wire is subjected to the plasma spraying of the base material of the FeCrAlY alloy consisting of about 5-40wt% Cr, about 3-20% Al, about 0.05-3% Y and the balance substantially Fe in the inert atmosphere under 50-500Torr, by which the W wire is compounded and united with said material in the 1st stage. The result ant composite material is subjected to the heat treatment in the vacuum for preferably about >=30min treatment time in a 1,000-1,300 deg.C temp. range.
