Researchers optimized laser deposition of aluminum oxide (Al2O3) on titanium (Ti64) for protective coatings. Key findings guide creating robust ceramic layers for demanding aerospace and automotive applications.

Area of Science:

  • Materials Science
  • Additive Manufacturing
  • Surface Engineering

Background:

  • Titanium alloys like Ti-6Al-4V (Ti64) require enhanced surface properties for high-temperature applications.
  • Ceramic coatings offer improved oxidation, wear, and thermal resistance.
  • Laser-directed energy deposition (DED-LB) is a promising additive manufacturing technique for creating these coatings.

Purpose of the Study:

  • Establish baseline process conditions for depositing Al2O3 beads on Ti64 using DED-LB.
  • Investigate the effects of laser power and scan speed on bead geometry and melt pool characteristics.
  • Optimize DED-LB parameters for minimal substrate dilution and robust ceramic layer formation.

Main Methods:

  • Al2O3 beads were deposited on Ti64 substrates using DED-LB.

  • Laser power and scan speed were systematically varied.
  • Bead geometry, melt pool depth, and dilution ratio were quantified.
  • Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS) and X-ray Diffraction (XRD) analyzed microstructure and phases.

    • Main Results:

    • Melt pool depth increased with higher laser power and lower scan speed.
    • Crack formation was more sensitive to laser power.
    • Bead height exhibited a non-monotonic response to energy density.
    • Optimized parameters (300 W, 400 mm/min, 3 g/min) yielded a low dilution ratio of ~40.27%.

    Conclusions:

    • Fundamental process guidelines for DED-LB of Al2O3 on Ti64 were established.
    • Mechanistic insights into bead formation, dilution, and interface characteristics were gained.
    • This work supports the development of DED-LB-based ceramic protective and functionally graded layers for Ti64 components.
