Abstract
The probability of formation of phosphides of some alloying elements (V, Mo, Cr, Mn, Co, W, Al, Fe, Ni, Si) was determined by using thermodynamic calculations. As shown by examinations of microstructure of metal deposited with flux-cored wires, which contain phosphorus, vanadium and phosphorus, molybdenum and phosphorus, and titanium and phosphorus, all of the above alloying elements lead to spheroidisation of phosphide inclusions, which makes promising the use of phosphorus as an alloying element for high-alloy surfacing consumables.
Keywords: arc surfacing, deposited metal, tool steel, phosphorus, phosphides, phosphide eutectics, thermodynamic calculations, prospects
