NASA Invents GRX-810 SuperAlloy with RAM
NASA recently invented a new high temperature 3D-Printed GRX-810 superalloy with almost double the tensile strength, more than double the ductility, and orders of magnitude (10X-2000X) better creep rupture life than conventional superalloys and current 3D-printable metal parts.
GRX-810 cannot be produced by conventional machining, and is 3D-printed. GRX-810 can be used in space launch systems, heat exchangers in nuclear power plants and other extreme temperature environments, thanks to RAM technology.
GRX-810 is made by coating NiCoCr metal powder with a film of nanoscale Y2O3 oxide particles using RAM technology.
Prior attempts to mechanically alloy the Y2O3 onto the metal powder with traditional equipment had deformed the powder. It became more platelet-like, had a tendency to stick, and as a result was much more difficult to print.
RAM rapidly and powerfully, yet gently coats the metal powder with the ceramic, without deforming the powder. The powder remains very spherical and flows well through the 3D printer.
Dissimilar Powder Mixing in 10 Seconds!
Dry ingredients can be difficult to thoroughly and consistently mix, particularly when the particles are of different sizes and characteristics. To illustrate effective and rapid mixing, 10 grams of fumed silica is blended with 100 grams of sand. Completed specimens exhibit no airborne fumed silica, demonstrating uniform blending at an order of magnitude difference in particle size.
Milling and Nano Coating in 8 Seconds!
Coating larger particles with smaller ones is a common processing application, and milling is often a part of the same process. In this video, agglomerated carbon black particles are simultaneously milled to nano size particles that coat the plastic pellets completely in just a few seconds. The high speed video clearly illustrates the dispersion of carbon black particles, their de-agglomeration, and progressive and comprehensive coating of the plastic pellets.
