New method to improve the performance of 3D printed alloys: adding titanium diboride nanoparticles

wallpapers Tech 2020-05-20
So far, 3D printed metal parts are still inferior to metal parts manufactured by traditional processes in many properties (especially strength). Scientists in Singapore have found a solution-by adding titanium diboride to the 3D printed alloy, they have successfully improved the power and thermal performance of the former.
 
In this study, the base alloy chosen by scientists is the nickel-based alloy 625 that has been widely used in the marine industry. It is composed of 55% -70% nickel, and other metals such as chromium, molybdenum, iron, niobium, tantalum, etc. It has high tensile strength and corrosion resistance.
In the experiment, they mixed the powder of this alloy with the dust of titanium diboride (particle diameter about 58 nanometers). They then used a laser 3D printer with a 6-axis robot arm to print a rectangle on a carbon steel substrate Prototype (size 120 mm × 70 mm × 10 mm, layer thickness 1 mm).
 
Finally, through testing, they found that this sample had better mechanical strength, thermal performance, and resistance to wear and corrosion than 3D printed parts of pure nickel-based alloy 625. They found the reason for this change-titanium boride nanoparticles gathered at the boundary between Inconel 625 grains, enhancing the grain boundaries.
