Layer build-up with MPA technology

Powder particles from the nozzle as well as the substrate surface undergo heavy plastic deformation on particle impact. In particular the impacting surface grains are getting highly stretched by local pressures exceeding 10 GPa and temperatures up to 1000°C. Within this process, a binding contact surface is created between powder particle and the subtrate. The subsequent plasticity of colliding particles during kinetic spraying leads to an isothermal heating of the whole component.
