Open the CIPO recordAbstract From the Canadian patent
The method provides a process for fabricating metal matrix composites. First theprocess coats the fibers with nickel by electrodeposition or gaseous deposition to form nickel-coated fibers. Over-plating the nickel-coated fibers with aluminum by either electrodeposition in a non-aqueous electrolyte or gaseous deposition forms aluminum-coated-nickel-coated fibers. Sintering this product under compression perpendicular to the fiber's central axis forms the, final metal matrix composite. The metal matrix composite has a nickel-aluminum matrix very, few voids and extended unbroken lengths of fibers within the nickel-aluminum matrix.

Why it's free to use
- Filed November 27, 1998 and granted August 20, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 27, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 27, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
