摘要： The invention comprises a process comprising infiltrating or infiltrating and coating a substrate with a boron-comprising precursor, and contacting the boron-comprising precursor with a nitrogen-comprising reactant to convert the boron-comprising precursor to BN or other a boron-nitrogen reaction product in the surface porosity or in the surface porosity and on the surface of the substrate. Composite materials comprising as one phase a substrate and BN or other a boron-nitrogen reaction product as a further phase, in surface porosity or in surface porosity and on a surface of the substrate, are claimed.

摘要： A method of forming metal parts or components from strip stock or roll stock without yielding is accomplished by first placing the part/components into fixtures that hold the stock in a non-yielding position therein. The fixture and metal stock parts are placed in a liquid, gas, or pack carburizing heat treatment process. Once the carburization process is complete, the part is released from the fixture with little or no spring back, maintaining the shape it was held in while in the fixture, resisting returning to its original shape, and optionally imparting spring-like qualities not associated with the stock before treatment.

摘要： Ferritic nitrocarburized surface treatment of cast iron brake rotors providing oxidation resistance, good braking performance and absence of distortion. Machined brake rotors are pre-heated, then immersed into a high temperature molten nitrocarburizing salt bath for a first predetermined dwell time. After removing the brake rotors from the nitrocarburizing salt bath, the brake rotors are directly immersed into an oxidizing salt bath at a lower temperature than the nitrocarburizing salt bath so that the brake rotors are thermally quenched. After a predetermined second dwell time in the oxidizing salt bath, the brake rotors are removed therefrom and further cooled to room temperature, either by water application thermal quenching or slow cooling in air. A fixture provides stable holding the brake rotors with a minimum of contact during placement in the salt baths.

摘要： A process of converting an outer layer of an object made of a refractory metal, such as titanium, into a carbide of the refractory metal. A molten metal, such as molten lithium, is placed adjacent the outer surface of the object. The lithium does not react with the titanium, nor is it soluble within the titanium to any significant extent at the temperatures involved. The molten lithium contains elemental carbon, that is, free carbon atoms. At high temperature, the carbon diffuses into the titanium, and reacts with titanium atoms to form titanium carbide in an outer layer. Significantly, no other atoms are present, such as hydrogen or oxygen, which can cause problems, because they are blocked by the molten lithium.
