| Abstract: | In this paper the author pointed out that spray welding powder Fe55 is directly melted on the surface of cast by the means of casting heat and alloy layer thick-ness 3. 0-3. 5mm obtained. As a result of metallographic analysis and energy spectrum it is concluded that the bonding between alloy layer and base metal belongs to metallur-gical bonding. The properties of alloy layer are similar with Fe55 powder. |
