Abstract
An implement including a first plate and a second plate, each plate having a contact surface which abuts a contact surface of the other plate to establish an interface plane, and a gradient of at least one additive that is more concentrated at the interface plane and less concentrated in decreasing amounts progressing away from the interface plane and the contact surface for each plate, wherein the at least one additive alters at least one property of each plate. Materials with internal gradients and methods of making same.

An implement comprising a first plate and a second plate, each plate having a contact surface which abuts a contact surface of the other plate to establish an interface plane, and a gradient of at least one additive that is more concentrated at the interface plane and less concentrated in decreasing amounts progressing away from the interface plane and the contact surface for each plate, wherein the at least one additive alters at least one property of each plate, wherein at least one of the first plate and the second plate is formed of a metallic material, wherein the interface plane has an outer boundary and the implement includes at least one working edge along at least a portion of the outer boundary of the interface plane, wherein the at least one additive increases hardness of the first and second plates, and the working edge is self-sharpening during use of the implement.
A method of making an implement comprising:
- selecting a first plate and a second plate, each plate having a contact surface, and at least one of the first plate and the second plate being formed of a metallic material;
- placing at least one additive on at least one of the contact surfaces;
- bringing the contact surfaces together;
- applying pressure to force the first plate and the second plate against each other;
- and
- applying at least one type of energy to the first plate and the second plate to fuse the plates together and to establish an interface plane at the contact surfaces with a gradient of the at least one additive that is more concentrated at the interface plane and less concentrated in decreasing amounts progressing away from the interface plane and the contact surface for each plate, wherein the contact surfaces abut each other and the at least one additive alters at least one property of each plate, wherein the interface plane has an outer boundary and the implement includes at least one working edge along at least a portion of the outer boundary of the interface plane, wherein the at least one additive increases hardness of the first and second plates, and the working edge is self-sharpening during use of the implement.
A material formed to have an internal gradient, the material comprising a first portion and a second portion, each portion having a contact surface which abuts a contact surface of the other portion to establish an interface plane, and a gradient of at least one additive that is more concentrated at the interface plane and less concentrated in decreasing amounts progressing away from the interface plane and the contact surface for each portion, wherein the at least one additive alters at least one property of each portion, wherein at least one of the first portion and the second portion is formed of a metallic material, wherein the interface plane has an outer boundary and the material includes at least one working edge along at least a portion of the outer boundary of the interface plane, and wherein the at least one additive increases hardness of the first and second portions, and the working edge is self-sharpening during use of the material.
An implement comprising a first plate and a second plate, each plate having a contact surface which abuts a contact surface of the other plate to establish an interface plane, and a gradient of at least one additive that is more concentrated at the interface plane and less concentrated in decreasing amounts progressing away from the interface plane and the contact surface for each plate, wherein the at least one additive alters at least one property of each plate, wherein at least one of the first plate and the second plate is formed of a metallic material, wherein the interface plane has an outer boundary and the implement includes at least one working edge along at least a portion of the outer boundary of the interface plane, and wherein the at least one additive increases corrosion resistance of the first and second plates to a corrosive fluid, and the working edge is self-sharpening during immersion of the implement in the corrosive fluid.
