Upgrading of the powder ribbon used for deposition

The design of the powder ribbon the filler of which is reliably fixed in the shell due to its being sprayed on the shell has been offered. It makes it possible to improve the quality of the sprayed layer by prevention of out-of-control spilling of the filler from the shell. The authors analyzed the means of improving the powder ribbon used for deposition by fixing its core by the introduction of the additives having high mold ability, followed either by heat treatment of the ribbon or by deforming the shell after filling it with the filler. The disadvantages of these technologies are less amount of the filler in the shell, the need for additional heat treatment, difficulties in stable supply of current to the ribbon. The paper suggests ways to improve the quality of the powder ribbon used for deposition by changing its structure. In the first case, in the production of the ribbon one more ribbon with transverse embossments arranged in staggered rows is placed in the shell. With its stretching closed cavities, keeping the filler from spilling, are formed
