Abstract

PURPOSE:To bury a void of a melt-sprayed film and make it dense by blowing evaporated vapor of W carbonyl or Mo carbonyl together with a hydrogen gas to the melt-sprayed film of W or Mo. CONSTITUTION:Powder of W carbonyl or Mo carbonyl is placed on the holding part 3 in the evaporating chamber 2 in a resistance heating furnace 1, and is heated to above 150 deg.C by means of resistance heating elements. At the same time, a hydrogen gas as a carrier gas is fed through a lead-in pipe 4 and is sent together with the vapor of evaporated W carbonyl and Mo carbonyl into a reaction chamber 6. The resistance heating furnace 5 containing the reaction chamber 6 is heated to raise temp. to above 500 deg.C, and the hydrogen gas and the vapor of carbonyl of W or Mo are blown to the melt-sprayed body 8 of W or Mo on a heating table 7 to reduce the carbonyl of W or Mo in the voids or gaps in the melt-sprayed film by means of hydrogen to metallic W or No, whereby the pores of the melt-sprayed film of W or Mo are buried to form dense melt-sprayed film.
