Laser deposition-additive manufacturing of Ti¿B/TiC ceramics reinforced microlaminates

Journal Article


Abstract


  • Ti-B/TiC ceramics reinforced microlaminates were fabricated by a laser cladding (LC) technique on the TC17 titanium alloy substrate made by the laser deposition-additive manufacturing technique. The Stellite 7-B4C mixed powders were used to produce a bottom-layer; then the Stellite 7-B4C-Al-Cu-Mn mixed powders were deposited on this bottom-layer to produce an upper-layer. With the addition of Al-Cu-Mn mixed powders, the AlCu2Mn UNs with a L21 (face-centered cubic system) structure were produced in an upper-layer, which increased the free energy of the crystal boundaries, and this can increase the density of the point defects, resulting in the lattice distortions. The identification of the AlCu2Mn UNs in the laser-treated composites contributes theoretical and experimental basis to improve the quality of the laser 3D print materials. To have a quantitative understanding of the strengthening effects, this paper has provided the laser-induced technological and the related theoretical basis to fabricate the ultrafine nanocrystals (UNs) modified microlaminates on the metal.
