Abstract
As an article for manufacture, a tin, lead, indium, alloys of each with a carbide or carbonyl former in an admixture for forming said tin, lead and indium, wettable graphite composites which will not dewet upon heating; methods for preparing the composites of various shapes, layers, coatings, and sandwiches, of alloys, preforms and metal-graphite etc, structures are also disclosed.
Claims15
A composite comprised of at least the following component parts of:
- (a) tin, lead, indium, a tin alloy, a lead alloy or an indium alloy in an amount from 60% to 99%, in combination with and, as a balance thereof, a metal which is a carbide or carbonyl former;
- and
- (b) a carbon or a silicon structure,
- wherein a bond between said components (a) and (b) is highly adherent and substantially void free, non-dewettable upon heat cycling, component (a) forms with a zero or negative angle of contact on component (b), an electrical resistance increase is substantially zero after the bond formation between components (a) and (b), and component (a) is capable of covering an entire surface of (b).

A sandwich composite comprised of at least component parts of:
- (a) tin, lead, indium, a tin alloy, a lead alloy or an indium alloy, in an amount from 60% to 99%, in combination with and, as a balance thereof, a metal which is a carbide or carbonyl former;
- (b) a carbon or a silicon structure, and
- (c) as an overlay on (a) at least one layer of:
- (i) a carbon structure, a silicon structure or
- (ii) a metal alloyable with said component (a),
- wherein a bond between said components (a), (b) and (c) is highly adherent and substantially void free, non-dewettable upon heat cycling, component (a) is capable of covering an entire surface of (b), component (a) forms with a zero or negative angle of contact on component (a) or with component (c) and an electrical resistance increase is substantially zero after the bond formation between components (a), (b) and (c).
