Technology Marketing Summary

Y-12 invites interested companies to license its patent-pending method known as TiBor Skin. This two-part technology enables creation and fabrication of toughened and corrosion- and wear-resistant composite structures. First, it provides a family of coatings or surface materials for application on metals plus methods of applying these materials. Second, it provides methods of interjoining the applied coatings with their substrates to form composite structures, the surfaces of which wear and corrode at rates much lower than those currently experienced in the industry.

DescriptionProvides a family of coatings or surface materials on substrate metal alloy systems for wear and corrosion applications.Method includes depositing a slurry or paste of titanium diborideand a flux along with other trace components on a substrate and heating the deposited material and the substrate to form a reinforced material interjoinedwith the substrate. The slurry, suspension, blend or mixture of selective materials can be deposited onto the surface using a number of methods such as painting, spraying, dipping, thermal spray, powder coating, etc. Laser, plasma, infrared, electron beam, induction, welding, microwave, etc. techniques can be used to reactively form the surface. Surface coatings formed by the approach change the surface characteristics of a component or structure to provide properties of high hardness, high temperature strength, wear and corrosion resistance and strong adherence to the substrate without changing the bulk material properties. Layers or functional grading can be employed to increase bonding strength and adherence or mitigate differences in coefficient of thermal expansion. Surface can be applied on finished components by portable, field techniques or fabricated on sheet materials prior to final manufacturing steps.Benefits• Integral—does not distort substrate geometry, reduce surface smoothness or allow for delamination

• Versatile—may be applied either to raw materials prior to manufacturing or to parts after manufacturing

• Nonrestrictive—does not interfere with welding process

• Thorough—replaces need for other coating techniques such as plasma spraying, sputtering and plating

• Broad—can also be employed to aid in bonding of dissimilar metals

Toughened and corrosion- and wear-resistant composite structures and fabrication methods thereof
Composite structures having a reinforced material interjoined with a substrate and methods of creating a composite material interjoined with a substrate. In some embodiments the composite structure may be a line or a spot or formed by reinforced material interjoined with the substrate. The methods typically include disposing a precursor material comprising titanium diboride and/or titanium monoboride on at least a portion of the substrate and heating the precursor material and the at least a portion of the substrate in the presence of an oxidation preventative until at least a portion of the precursor material forms reinforced material interjoined with the substrate. The precursor material may be disposed on the substrate as a sheet or a tape or a slurry or a paste. Localized surface heating may be used to heat the precursor material. The reinforced material typically comprises a titanium boron compound, such as titanium monoboride, and preferably comprises .beta.-titanium. The substrate is typically titanium-bearing, iron-bearing, or aluminum-bearing. A welding rod is provided as an embodiment. The welding rod includes a metal electrode and a precursor material is disposed adjacent at least a portion of the metal electrode. A material for use in forming a composite structure is provided. The material typically includes a precursor material that includes one or more materials selected from the following group: titanium diboride and titanium monoboride. The material also typically includes a flux.
