Abstract
Effect of initial structure and particle size composition of additive powder PG-10R6M5 on structural state of deposited metal produced by plasma-powder cladding using the above powder was investigated. It is shown that the effect of inheritance of structure of the PG-10R6M5 powder by the deposited metal takes place in cladding: the higher the content of the -phase in the powder, the higher its content in the deposited metal, the content of the -phase decreasing accordingly.
