Surface reinforcements of TA15 titanium alloy with laser induced Co base multiphase composites

Journal Article


Abstract


  • © 2020 Elsevier Ltd Ultrafine particles (UPs)/amorphous phases (APs) reinforced composites was deposited on the TA15 titanium alloy via a laser cladding (LC) of the Co-Al-B4C-CeO2 mixed powders; a LC technique (the laser power 900 W, the scanning speed 2.5 mm/s) favored APs/UPs to be produced owing to the transient existence of the laser molten pool (laser pool), its COF was in a range of 0.390–0.425. Then, the monolayer graphene oxide sheets (MGOSs)/carbon nanotubes (CNTs) reinforced composites were formed on this LC fabricated coating by a mean of LC of Co-Al-B4C-CeO2-(MGOSs/CNTs). Noting that a laser beam irradiated on MGOSs/CNTs also the pre-melted powders, huge amounts of MGOSs/CNTs were melted but kept partial MGOSs/CNTs in the solid states; also lots of UPs were produced in the atomic arrangements of APs/MGOSs, considering that partial UPs could obtain large quantity of the energy from a laser beam, forming lattice distortions. Identification of the synthetic UPs and MGOSs/CNTs in such LC composites, more importantly an UPs’ effect, contributes the theoretical/experimental basis to improve quality of the laser 3D print fabricated composites.
