Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
67 words
A titanium clad steel plate in which a layer of a titanium or titanium alloy cladding metal is bonded to a layer of a carbon steel or low-alloy steel base metal by an intermediate metal layer interposed between the cladding metal layer and the base metal layer, characterised in that the intermediate layer is a layer of a metal selected from the commercially pure niobium and tantalum.
Claim 2
Dependent Claim
67 words
A titanium clad steel plate in which a layer of a titanium or titanium alloy cladding metal is bonded to a layer of a carbon steel or low-alloy steel base metal by an intermediate metal layer interposed between the cladding metal layer and the base metal layer, characterised in that the intermediate layer is a layer of a metal selected from the commercially pure niobium and tantalum.
Claim 3
Dependent Claim
41 words
A titanium clad steel plate as claimed in claim 1 in which the intermediate metal layer is bonded to the base metal layer by an interposed supplemental intermediate layer of a metal selected from copper, copper alloy, nickel and nickel alloy.
Claim 4
Dependent Claim
19 words
A titanium clad steel plate as claimed in claim 1 or 2, wherein the clad plate is hot rolled.
Claim 5
Dependent Claim
26 words
A titanium clad steel plate as claimed in claim 1 or 2, wherein the cladding metal layer consists of two layers of titanium or titanium alloy.
Claim 6
Dependent Claim
28 words
A titanium clad steel plate as claimed in claim 1, 2 or 4, wherein the base metal layer consists of two layers of carbon steel or low-alloy steel.
Claim 7
Dependent Claim
19 words
A titanium clad steel plate as claimed in claim 4 or 5, wherein the clad plate is hot rolled.
Claim 8
Independent Claim
54 words
A method of manufacturing titanium clad steel plate, characterised in that a cladding metal plate consisting of titanium or a titanium alloy and a base metal plate consisting of carbon steel or low-alloy steel plate are respectively bonded to opposite surfaces of an intermediate plate of metal selected from commercially pure niobium and tantalum.
Claim 9
Independent Claim
54 words
A method of manufacturing titanium clad steel plate, characterised in that a cladding metal plate consisting of titanium or a titanium alloy and a base metal plate consisting of carbon steel or low-alloy steel plate are respectively bonded to opposite surfaces of an intermediate plate of metal selected from commercially pure niobium and tantalum.
Claim 10
Dependent Claim
45 words
A method as claimed in claim 7 in which the bonding process includes bonding the base metal plate and the intermediate metal plate to opposite sides of a supplemental intermediate plate of a metal selected from copper, a copper alloy, nickel and a nickel alloy.
Claim 11
Dependent Claim
41 words
A method as claimed in claim 8 in which the intermediate metal plate and the supplemental intermediate metal plate are bonded to each other and rolled prior to bonding with the cladding and base metal plates into a composite metal plate.
Claim 12
Independent Claim
22 words
A method as claimed in any one of claims 7 to 9 in which the titanium clad steel plate is hot rolled.
Claim 13
Independent Claim
43 words
A method as claimed in any one of claims 7 to 10 in which a further cladding metal plate and/or a further base metal plate is bonded to the respective cladding metal plate or base metal plate already bonded to the intermediate plate.
Claim 14
Dependent Claim
18 words
A method as claimed in claim 11 in which the manufactured titanium clad steel plate is hot rolled.
Claim 15
Independent Claim
29 words
A method as claimed in any one of claims 7 to 11 in which the bonding of the plates is conducted by explosive bonding, roll bonding or diffusion bonding.
