A method of making heat engine components, such as rocket nozzle throats, includes forming a body having at least one surface, wherein the body is made of a refractory metal, and compressing a ceramic powder between a die and the at least one surface of the body, with sufficient heat and pressure to densify and thus form a solid ceramic coating on the at least one surface of the body. Nozzle throats made according to the invention have bodies made of refractory metals, such as tantalum, and ceramic coatings on the inner surfaces of the annular bodies, wherein the ceramic coatings are made of ceramic materials such as tantalum carbides (TaC and Ta C).

Embodiments include a disk drive having a drive motor assembly including at least one component selected from the group consisting of a rotatable hub, disk spacer, disk clamp, backiron, lower bearing bushing, and lower mounting flange. At least one of the components comprises a low sulfur outgassing free machining stainless steel material. The low sulfur outgassing free machining stainless steel material may include a free machining stainless steel that outgases sulfur at a rate insufficient to cause visually observable sulfide corrosion when tested by placing a copper strip into contact with the free machining stainless steel in an environment having a temperature of 50. degree. C. and 90% relative humidity for a 7 day test period and then observing the copper strip.

A composition and method for producing a low density, high stiffness aluminum alloy which is capable of being processed into structural components having a desired combination of tensile strength, fracture toughness and ductility. The method includes the steps of forming, by spray deposition, a solid Al-Li alloy workpiece consisting essentially of the formula Al. sub. bal Li. sub. a Zr. sub. b wherein "a" ranges from greater than about 2. 5 to 7 wt %, and "b" ranges from greater than about 0. 13 to 0. 6 wt %, the balance being aluminum, said alloy having been solidified at a cooling rate of about 10. sup. 2 to 10. sup. 4 K/sec. The method further includes several variations of selected thermomechanical process steps for: (1) eliminating any residual porosity which may be present in the workpiece as a result of the spray deposition step; and (2) producing components for a wide range of applications.
