Metal powder and laser-based manufacturing

Bullet Functionalization of surfaces and improvement of surface properties via laser

Ceit is a pioneer in using femtosecond (ultrashort pulse) lasers to develop industrial applications. This type of laser allows materials to be processed with micrometric precision and without thermal heating. It has been successfully applied to the functionalization of surfaces in order to:

  • Introduce decorative elements

  • Increase hydrophobicity

  • Define precise optical effects

  • Increase the durability of parts against friction

  • Improve the integration of implants with different tissues

Bullet Manufacture of metal powder via water or gas atomization

Ceit has the capacity to produce via atomization alloys that have a melting point up to 1700 °C in powder form.

Both standard and experimental compositions for specific applications can be atomized from various families of alloys (steels; nickel, iron or cobalt-based superalloys; aluminum alloys; bronze, brass and other copper-based alloys; magnetic materials, etc.).

Each powder's properties are tailored according to its use in various sectors (automotive, aeronautical, biomedical, transportation, energy, industrial, etc.) and processing technology (press and sinter, additive manufacturing, hot isostatic pressing, hot pressing, thermal spraying, etc.):

  • Composition: Very low levels of oxygen and other impurities.

  • Particle shape: Spherical (gas atomization) or irregular (water atomization).

  • Particle size distribution: Average particle size between 10 and 100 microns.

Bullet Pressed and sintered water atomized powder

  • 30 and 100 Tn hydraulic press.

  • Instrumentation. Stress vs. displacement curves.

  • Compaction curves. Near net shape technologies.

  • Complex tool design (punches and dies) for metal and ceramic powders.

  • Cold isostatic pressing.

  • Sintering and presintering furnaces and muffles.

  • Thermal treatment equipment.

  • Design and control of sintering atmospheres (endogas, exotermic, H2-N2, inert).

  • Measurement of oxygen activity, dew point, CO2, CO, etc.

  • Thermal shock simulation equipment.

  • High vacuum furnaces for thermal treatment of AM parts (Ti6Al4V and superalloys).

  • Salt furnace. Graphitization furnace up to 3000ºC.

  • Hot uniaxial press (1500ºC-35 MPa).

  • Hot isostatic press (1800ºC-150 MPa).
