The composite wire compound calculation methods were considered, factoring stoichiometric ratio values of the elements of the intermetallic γ'-Ni3Al, draft, elongation and compaction of the filling’s components as well as the values of alloy transfer effervescive. It is found that during argon-arc surfacing the components of the composite wire’s filling and coating are melting uniformly at the welding current density from 30 to 50 A/mm2. The correlation was established between the composition, the construction of the composite wire for arc welding and surfacing and the structure of Ni3Al based deposited metal. It is shown that the developed composite wire provides the deposited metal with the structure of nickel aluminide economically alloyed with wolfram, molybdenum, tantalum and chrome. |
