Abstract

For the first time, components can be produced from MAX-phases due to the use of an additive production method. A method for producing a component from MAX phases, in particular from Ti3SiC2 and/or Cr2AlC, in which an additive manufacturing process is disclosed. Powder is applied layer by layer and densified, the grain sizes of the powder lying at 10 μm to 60 μm, in which the scanning speed between the energy beam of the laser or electron beam and substrate with powder lies between 400 mm/s and 2000 mm/s, in particular at 1000 mm/s to 1500 mm/s, in which the power output is between 80 W and 250 W, in particular is 100 W to 170 W, in which a spot size of the energy beam lies between 30 μm and 300 μm.
