Abstract
Technology of obtaining complex ligatures by means water atomization of alloys as opposed to mechanical crushing individual ferroalloys is proposed. Complex ligatures based on manganese such as Mn-Si-Mo-Ni, Mn-Mo-Ni, Mn-Mo-Ni-Ti, Mn-Si-Mo-Ni-Ti, Mn-Si-Mo-Ni and Mn-Si-Ni-Cr-Mo obtained at pressure of water up to 5,5 MPa have high fluidity, fine size of phases, and ensure quenching rate within 105-107 К/s. Using powder complex ligatures based on manganese at production of powder wire it is possible to achieve high technological and mechanical properties of welded joint, in particular in operating at low temperatures, and to improve ecological status, fire and explosion safety due to passivating powders during high pressured water atomization of melts. As a result of the experimental studies it was found: 1. The use of complex ligatures of the system Mn-Si-Mo-Ni, Mn-Mo-Ni, Mn-Mo-Ni-Ti, Mn-Si-Mo-Ni-Ti, Mn-Si-Mo-Ni and Mn-Si- Ni-Cr-Mo as an additive in the electrode wire is more appropriate than the use of individual components of the complex ligatures. The use of sputtered alloy powders instead of mechanical crushing of simple ferroalloys of their own chemical composition and their mixtures lead to a homogeneous structure and increase of technological parameters and quality of the electrodes.
