Example Embodiment

[0024] Example 1:

[0025] The TA15 titanium alloy was cut into a cuboid with a length of 30 mm, a width of 10 mm, and a thickness of 10 mm. Before laser processing, clean the surface of the titanium alloy, wipe and blow dry. Set the mass score to 89% Stellite 12, 10% B 4 C, 1%Y 2 O 3 The mixed powder is laser alloyed on the 30 mm×10 mm surface of the titanium alloy to form the lower layer; afterwards, the mass fraction is 84% ​​Stellite 12, 10% B 4 C, 5%Cu and 1%Y 2 O 3 The mixed powder is laser melted and deposited on the lower layer to form the upper layer. The specific process steps are as follows:

[0026] (1) Before laser alloying, polish the cut TA15 titanium alloy surface to be laser treated with 240 grit sandpaper to make the surface roughness Ra 2.5 μm; then, rinse with clean water, and then use alcohol to melt the surface Wipe clean and blow dry;

[0027] (2) Weigh 89 g and B of Stellite 12 powder with a balance 4 C powder 10 g, Y 2 O 3 1 g of powder, put it into the No...

Abstract

The invention discloses a method for preparing a quasicrystal-nanocrystalline modified gradient composite through a laser 3D printing technology. Stellite 12-B4C-Y2O3 mixed powder is alloyed on the surface of TA15 alloy in a laser mode through a coaxial feeding method to form a lower layer of a thick structure. Stellite 12-B4C-Cu-Y2O3 mixed powder is deposited on the surface of the lower layer ina laser mode to form an upper layer of a compact structure. Good alloyed combination between the upper layer and the lower layer is formed, and both the upper layer and the lower layer have good abrasion resistance. The experiment result shows that many superfine nanocrystalline and quasicrystalline phases are generated along with addition of Cu, the structure of the gradient composite layer manufactured in the laser additive mode is changed, and the mechanical performance of the gradient composite layer is improved. Through the method, the gradient composite of the compact structure and withsuper-high abrasion resistance can be obtained.
