Process parameters of the multilayer laser cladding of the bronze B10 alloy powder are experimentally investigated. The 3-D structures are prepared trace-on-trace by remelting of the powder injected into the processing zone through a nozzle. An efficient formation of the volumetric structures of controlled geometry is observed. Microanalysis of the samples confirm the expected mechanical properties, low porosity and the highly homogeneous structure of the multilayers. For the subsequent clads of 1 mm width and 0,6 mm in height produced at velocities of 1m/min. the process efficiency of about 5% is obtained.
