摘要： A method of braze joining a copper member to a substrate of metal or ceramic material is disclosed according to which a diffusion barrier coating as defined is applied to the substrate alone, and a selected brazing alloy is interposed between copper member and substrate, followed by a two-step heating treatment. In the first step the assembly is heated at a temperature and for a time sufficient to melt the brazing alloy and cause a bond to form between the brazing alloy and the copper member and between the brazing alloy and the substrate. In the second step the temperature is raised and maintained in the range from about 600.degree. C. to about 950.degree. C. in a "solutionizing heat treatment" (as defined) for a time sufficient to allow the brazing alloy to form an "extended solid solution" (as defined) with copper in a controlled fashion to convert the bond to a strong joint which is resistant to thermal stress.

摘要： A method is disclosed for producing a hollow airfoil, specifically, a blade or vane for a gas turbine engine, which is formed with a complex interior for cooling purposes. Broadly, the method comprises the steps of molding a green ceramic core having outer surfaces generally contoured to produce the intended interior surfaces of the completed airfoil, heating the green ceramic core to a sufficient extent to produce a fired core, and operating on the fired core with a laser to modify the characteristics of the fired core. Use of the laser enables the formation of detailed features having a transverse dimension less than approximately 0.020 inches. Specific operations may include labeling, trimming, cutting, drilling either by punching or trepanning, etching or milling, and glazing or strengthening. In another embodiment of the invention, a layer is produced on the core surface having a very high surface energy to promote the flow of the casting alloy around the core within the mold.

摘要： Pulsed light sources, such as a flashlamp or laser, remove coatings from substrates via the ablation method. A photodetector circuit, sensing reflected light from the surface being ablated, provides a feedback signal that indicates the reflected color intensity of the surface being ablated. The boundary between the coatings or substrate surfaces is distinguished by a change in color intensity between an upper coating and an undercoating, e.g., between a topcoat of paint and a primer coat of paint, or between a coating and the substrate surface itself. The color intensity determination thus provides a measure relative to when one coating has been removed and another coating remains. The photodetector circuit is also useful for providing feedback information relative to the quality of a stripped work surface for quality control or other purposes.

摘要： A ceramic hydrodynamic bearing used as a radial or a thrust bearing in a spindle motor for a hard disk driver. The bearing includes a ceramic bearing base having hydrodynamic pressure generating grooves. A sliding surface of the bearing base is irradiated with an energy beam with a high energy density to remove said material, thereby forming hydrodynamic pressure generating groove, and at the same time the grooves are coated with a modification layer that is formed by melting the ceramic material that constitutes said ceramic bearing base with the energy beam and by solidifying said ceramic bearing base.

摘要： A method of forming optical quality surfaces in optical material is described. In particular, high optical quality end face surfaces are provided in diffused channel waveguides formed on LiNbO.sub.3 crystal material, or the like. A T-shaped trench is first formed by laser ablation. The top of the "T" bisects a plane orthogonal to and passing through the waveguide. The lower part of the "T" is centered on the longitudinal axis of the waveguide and retains an optical fiber abutting the end face.A diamond polishing wheel is inserted in the top trench to polish the end face prior to affixing the fiber optic.
