Abstract
A blender blade formed of titanium or titanium alloy is described herein. The blender blade comprises a central portion and one or more blade wings extending therefrom. Each blade wing comprises a leading edge, wherein the leading edge is work hardened to cause the leading edge to have a first hardness which is harder than a second hardness of the central portion. The central portion is in an annealed condition. The first hardness is in a range of about 40-50 HRC, the second hardness is in a range of about 20-30 HRC. Subsequent to work hardening, the leading edge can undergo nitriding and/or layer deposition.
Claims18
A blender that comprises:
- a rotatable shaft that includes a threaded end;
- a blender blade that is configured to slice foodstuff placed into the blender as the rotatable shaft rotates about an axis, wherein the blender blade comprises:
- a central body portion that is coupled to the threaded end of the rotatable shaft via an aperture of the central body portion and a fastener, the central body portion is formed entirely of titanium or a titanium alloy;
- and
- a blade wing that extends from the central body portion, the blade wing is formed entirely of the titanium or the titanium alloy,
- wherein the blade wing is covered with a layer of titanium nitride, wherein the central body portion is not covered with the layer of titanium nitride.
A method comprising:
- providing a blender blade made entirely from titanium or a titanium alloy, wherein the blender blade comprises a central body portion and a blade wing that extends from the central body portion, wherein the blade wing is covered with a layer of titanium nitride, wherein the central body portion is not covered with the layer of titanium nitride;
- and
- coupling, with a fastener, an aperture of the central body portion of the blender blade to a threaded end of a rotatable shaft of a blender, wherein when the rotatable shaft rotates about an axis, the blender blade is configured to slice foodstuff placed in the blender.
