Abstract
A method for connecting or joining a first substrate and a second substrate across an interface between the first substrate and the second substrate. The method includes disposing a fastener precursor in the bore and sintering the fastener precursor in the bore. The fastener precursor densifies and shrinks in at least one dimension to mechanically interlock with a contour in the bore and form a mechanical fastener in the bore, and the mechanical fastener forms an interlock between the first substrate and the second substrate.
Claims18
A method for connecting or joining a first substrate and a second substrate across an interface between the first substrate and the second substrate, the method comprising:
- disposing a fastener precursor in a bore that extends into the first substrate and the second substrate;
- and
- sintering, without shrinking the first and second substrates, the fastener precursor in the bore, wherein the fastener precursor densifies and shrinks in at least one dimension to mechanically interlock with a contour in the bore and form a mechanical fastener in the bore, and wherein the mechanical fastener forms an interlock between the first substrate and the second substrate.
