摘要: Methods for forming protective coatings on aerospace components are provided. In one or more embodiments, the method includes exposing an aerospace component to a first precursor and a first reactant to form a first deposited layer on a surface of the aerospace component by a first deposition process (e.g., CVD or ALD), and exposing the aerospace component to a second precursor and a second reactant to form a second deposited layer on the first deposited layer by a second deposition process. The first deposited layer and the second deposited layer have different compositions from each other. The method also includes repeating the first deposition process and the second deposition process to form a nanolaminate film stack having from 2 pairs to about 1,000 pairs of the first deposited layer and the second deposited layer consecutively deposited on each other.

摘要: A method of coating particles includes dispensing particles into a vacuum chamber to form a particle bed in at least a lower portion of the chamber that forms a half-cylinder, evacuating the chamber through a vacuum port in an upper portion of the chamber, rotating a paddle assembly such that a plurality of paddles orbit a drive shaft to stir the particles in the particle bed, injecting a reactant or precursor gas through a plurality of channels into the lower portion of the chamber as the paddle assembly rotates to coat the particles, and injecting the reactant or precursor gas or a purge gas through the plurality of channels at a sufficiently high velocity such that the reactant or precursor a purge gas de-agglomerates particles in the particle bed.

摘要: A reactor for coating particles includes a vacuum chamber configured to hold particles to be coated, a vacuum port to exhaust gas from the vacuum chamber via the outlet of the vacuum chamber, a chemical delivery system configured to flow a process gas into the particles via a gas inlet on the vacuum chamber, one or more vibrational actuators located on a first mounting surface of the vacuum chamber, and a controller configured to cause the one or more vibrational actuators to generate a vibrational motion in the vacuum chamber sufficient to induce a vibrational motion in the particles held within the vacuum chamber.

摘要: A method of preparing a pharmaceutical composition having a drug-containing core enclosed by one or more silicon oxide materials is provided. The method entails alternating exposing the particles to gaseous or vaporous SiCl4 and gaseous or vaporous H2O at a reduced temperature and in the absence of a catalyst.

摘要: A reactor for coating particles includes a rotatable reactor assembly includes a reactor drum configured to hold a plurality of particles to be coated, an inlet tube, and an outlet tube. The drum includes a cylindrical tube, and an inlet-side endplate secured to cover an inlet-side opening of the cylindrical tube and/or an outlet-side endplate secured to cover an outlet-side opening of the cylindrical tube. A stationary gas inlet line is coupled to the inlet tube by a rotary inlet seal, a stationary gas outlet line is coupled to the outlet tube by a rotary outlet seal, and a motor rotates the rotatable reactor assembly. The inlet tube is releasably mechanically secured to the inlet-side endplate and the outlet tube is releasably mechanically secured to the outlet-side endplate.

摘要: A pharmaceutical composition containing a metal oxide coated particle comprising 1) an amorphous solid dispersion (ASD) core containing an active pharmaceutical ingredient (API) and a polymer; and 2) a metal oxide coating, and the method of making said metal oxide coated particle by atomic layer deposition (ALD). The metal oxide coated particle is useful because it prevents the ASD from crystallization and helps maintain the ASD in an amorphous form.
