<p>A powder material moved and mixed by the application of a mechanical force. The moving of the bed of powder in a container while the container is in a vacuum under a vapor source produced by magnetron sputtering, thermal evaporation, or other means of producing a coating vapor such as plasma enhanced chemical vapor deposition (PECVD), provides a means of coating the particles of powder with a material which will impart certain other desirable characteristics to the base material of which the powder is composed. The range of and combinations of coatings include a pure metal, co- deposited metals, and non-metals formed by reactive magnetron sputtering, evaporation or PECVD, or a sequentially deposited coating of both metals and non-metals. The mechanical means maybe by striking, stirring or a piezoelectric transducer may be used. The mechanical force may be imposed on an open moving container of the bulk material in a vacuum or an open stationary container of the bulk material in a vacuum.</p> |
