Modification of microstructure weld layers based cored wire with addition Al, Mg
Abstract
Surfacing materials system Fe–Cr–B–C are widely used for the restoration and strengthening of machine parts. The peculiarity of this material is satisfactory durability under conditions of abrasive wear. However, presence of shock adversely affects the durability clad layers as microstructure consisting of coarse solid phases are hubs to create microcracks. In work the deposited layers of powder wire PD Cr10B4 which were put in charge of powdered additives PA and AMP. Established that the application of PA and AMP affect the microstructure dendritic Rounding off axis.References
