| Abstract Scope |
It was studied the dependences of the protective argon-helium mixture influence on the heat input meaning for the process of layer-by-layer electric arc surfacing with wire, and the effect of parameters changes in this process on composition, properties and structure of AlSi5 and AlMg5 aluminum alloys. Helium contain in argon was at a ratio of 10% to 50% in 10% increments. It was found, that with the amount increase of helium the concentration of the arc increases and the amperage required to melt the metal decreases.
It was found that the heat input meaning increasing provides the improvement of metal structure and properties for both of studied aluminum alloys. The addition of helium can reduce the amount of heat input required to obtain higher mechanical properties. |
