Abstract
A system and method for friction stir processing of an industrial blade, wherein friction stir processing techniques are used to modify the properties of the industrial blade to thereby obtain superior edge retention and superior resistance to chipping.
Claims20
A method for creating an industrial blade, said method comprising the steps of:
- 1) providing a high melting temperature workpiece that is to be formed into an industrial blade;
- 2) providing a friction stir processing tool that includes a higher melting temperature material than the workpiece on a portion thereof;
- and
- 3) friction stir processing the workpiece using the tool to thereby modify characteristics thereof;
- and
- 4) forming the industrial blade from the workpiece.
The method as defined in claim 15 wherein the method further comprises the step of friction stir processing without plunging the pin into the workpiece.
A hand-held knife with a blade having improved edge retention and resistance to chipping, said industrial blade comprised of a high melting temperature workpiece, wherein the high melting temperature workpiece is created through friction stir processing.
A system for manufacturing a hand-held knife blade through friction stir processing, said system comprised of:
- a high melting temperature workpiece;
- and
- a friction stir processing tool that includes a higher melting temperature material than the workpiece on a portion thereof, wherein the tool is used to perform friction stir processing to thereby cause solid state transformation of the workpiece, wherein characteristics of the workpiece are modified.
