1. 48% Cr) is melted in an 100 kg induction furnace up to 1 580 ℃
the metal liquid flows through furnace bottom liquid conduct nozzle and sprays in atomized chamber by high pressure nitrogen flow to atomize micron liquid drops and form deposition billet at bottom. The compared analysis on pore distribution
microstructure and density of spraying formed steel GCrl5 has been carried out by using optical microscope
scanning electron microscope. Results show that there are macro-pores at deposition billet cross section and irregular-shaped micro-pores distributed in whole deposition billet. The average relative density of whole deposited billet is 85. 51%.
