| 摘要 |
The invention relates to the encapsulation of Geldhart class C substrate powders with a coating of metal, binder, or sintering aid. Encapsulation is achieved using chemical vapor deposition techniques in a recirculating fast-fluidized or turbulent fluidization flow bed reactor. Thin, smooth, generally uniform, fully encapsulating coatings are produced on the fine substrate particles. The coated Geldhart class C particles, and products made therefrom, exhibit excellent improved physical properties.
