The influence of technological parameters on the structure formation of aluminum alloys during direct deposition of wire

The paper presents the results of an investigation of application arc, laser and laser-arc sources for process direct deposition of aluminum wire. Experimental studies have focused on the determination mode of parameters to provide uniform formation of a thin wall during successive layering. The metallographic analysis of cross-sections of the samples was performed. The microhardness, chemical and mechanical tests were carried out. (paper)
