The method includes the steps of locating an asteroid, making contact with the asteroid using meteorites on earth, harvesting material from the asteroid, processing material from the asteroid producing additive manufacturing quality powder, using the additive manufacturing quality powder as a feed stock for additive manufacturing in space, and completing the parts or products by the additive manufacturing in space.

Method of applying a thermal barrier coating to a metallic article and a thermal barrier coated metallic article

A thermal barrier coated metallic article includes a platinum-group metal enriched outer layer on the article. The surface of the outer layer has a microstructure including a plurality of projections extending away from the metallic article. A thin adherent layer of oxide is formed on the outer layer of the metallic article. A ceramic coating is provided on the oxide layer on the surface on and around the projections. The ceramic coating includes a plurality of columnar ceramic grains which extend through the full thickness of the ceramic coating. The grains are arranged in clusters separated by gaps. The grains deposited around the projections are generally blocked. The projections reduce the stress in the ceramic coating near the interface with the adherent layer of oxide and also reduce the stress in the adherent layer of oxide and hence increase the working life of the thermal barrier coating system.

MEDICAL DEVICES AND INSTRUMENTS WITH NON-COATED SUPERHYDROPHOBIC OR SUPEROLEOPHOBIC SURFACES
20240366844 · 2024-11-07 ·

Device surfaces are rendered superhydrophobic and/or superoleophobic through microstructures and/or nanostructures that utilize the same base material(s) as the device itself without the need for coatings made from different materials or substances. A medical device includes a portion made from a base material having a surface adapted for contact with biological material, and wherein the surface is modified to become superhydrophobic, superoleophobic, or both, using only the base material, excluding non-material coatings. The surface may be modified using a subtractive process, an additive process, or a combination thereof. The product of the process may form part of an implantable device or a medical instrument, including a medical device or instrument associated with an intraocular procedure. The surface may be modified to include micrometer- or nanometer-sized pillars, posts, pits or cavitations; hierarchical structures having asperities; or posts/pillars with caps having dimensions greater than the diameters of the posts or pillars.
