Abstract
The paper demonstrates the advantages of thermal power plant slime over marble, which is traditionally applied as gas-slag-forming component of welding consumables. Electrochemical investigations and gravimetric corrosion testing demonstrated the high quality of deposited Cr-Ni metal and the possibility of applying slime in electrode manufacture
Keywords: thermal power plant slime, deposited metal, metallographic and electrochemical investigations, petrographic analysis, nоn-metallic inclusions, welding slags, corrosion, mechanical properties
