Abstract

1276615 Sinter bonding metal components NATIONAL-STANDARD C O 2 April 1970 [18 April 1969] 156793/70 Heading C7D A method of sinter bonding metal components e.g. for cladding, or sealing a mine in the bore of a tube, comprises placing a metal part in juxtaposition to a compacted reducible metal compound powder, heating the assembly to reduce the compound and then heating to sinter bond the components together. The metal compound is preferably a steel or iron mine which is inserted into the bore of an extruded metal compound tube formed from a powder mixture of a binder such as corn starch and either iron oxide formed from spent pickle liquor, or copper oxide, or a mixture of iron oxide nickel oxide and Fe Cr which produces a stainless steel on reduction. The metal compound particles are preferably < 10 microns with an average size of 0À8 microns and with 90% weight < 2.5 microns. With the iron - iron oxide assembly, heating is at 1100 ‹F. and 2100 ‹F. , with the iron - copper oxide at 700‹F. and 1800‹F. and with the iron - stainless steel components at 1100‹F. and 2200‹F. Formulae are included for calculating the shrinkage of the green metal compound in order to determine the required mine size for a given tube bore diameter. The mine diameter is preferably less than the inner diameter of the green tube and the same diameter as the sintered inner diameter at the bonding sections.
