US Patent:

54476984, Sep 5, 1995

Filed:

Aug 5, 1994

Appl. No.:

8/286719

Inventors:

Sunil C. Jha - North Attleboro MA
James A. Forster - Barrington RI

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

B01J 3200
B01J 3504
B23K 2004

US Classification:

422180

Abstract:

A metal foil substrate material for catalytic converters and method of making the material in which layers of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a composite material. Such composite material is further rolled to the final foil gauge with no heat treatment and then subjected to a thermal in situ reaction to form a resulting uniform solid solution foil material with superior high temperature corrosion resistance.

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

B23K 2004
C21D 800

US Classification:

148531

Abstract:

A metal foil substrate material 50 for catalytic converters 54 and method of making the material in which layers (10, 12, 14) of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a composite material 24. Such composite material 24 is further rolled to the final foil gauge with no heat treatment and then subjected to a thermal in situ reaction to form a resulting uniform solid solution foil material 50 with superior high temperature corrosion resistance.

International Classification:

B23K 2004
B21D 5304

US Classification:

228190

Abstract:

A self-brazing material 10 for use in a heat exchanger 50 using a corrosive heat exchanger fluid is manufactured by providing a first substrate layer 10 and a second layer 12 metallurgically bonding the two layers together to form a composite material 22. This second layer 12 is made of a material chosen from a group consisting of materials capable of having good high temperature and corrosive properties, and melting at a temperature well below that of the first material 10. The bonded material 22 is then reacted so as to render the second layer 12 a brazing layer for the first substitute layer 10 with excellent high temperature and corrosive properties.
