    Abstract: A protective coating is applied to a bell body composed of bronze by simply dip-coating the bell with an outer layer of zinc. The process is carried out by immersing the bell body in a hot aqueous solution containing sodium hydroxide and powdered free zinc. After the bell is removed from the coating solution it is rinsed and then polished. The coating protects the bell from environmental contaminants without changing the frequency or musical quality of the bell and therefore may be used equally with newly manufactured or refurbished bells.

  • Patent number: 6495272
    Abstract: A method of producing high quality optical surfaces is disclosed. The invention allows for the production of optical surfaces with complex geometry while retaining the high quality of the optical surface. A top layer is provided on a substrate. In order to adhere the top layer to the substrate, an adhesion layer is applied first. In the preferred embodiment, the substrate is an aluminum substrate, the adhesion layer includes a layer of zinc and a layer of nickel and the top layer is gold. The substrate is generally stress free in order to provide a flat surface with no undulations. This allows a relatively thin layer of gold to be applied which then can be diamond turned in order to achieve a reflective layer.

  • Patent number: 6419992
    Abstract: A zinc coating directly covers a bare ferrous base of parking meter housing parts. A non-epoxy thermosetting electrically insulating organic non-epoxy powder coating directly covers the zinc coating. The organic coating is directly applied to the zinc coating by electrostatically charging the powder and parts with opposite d.c. voltage polarities and by heating the powder so it adheres to and covers the zinc coating. Alternatively, the base is zinc, directly covered by the organic powder coating.

  • Patent number: 6403165
    Abstract: A method for producing a turbine airfoil that is coated with a beta phase, high aluminum content coating, such as substantially stoichiometric NiAl, and which has a surface finish suitable for application of a ceramic topcoat. The method involves impacting the coating with preselected particles of a preselected size so that the brittle coating is not adversely affected by chipping or breakage. The impacting produces a surface finish of 120 micro-inches or better so that a ceramic thermal barrier layer can be applied over the coating. The preferred method of improving the surface finish utilizes steel balls having a diameter of about 0.033″ and a peening intensity of no greater than about 6 A.

  • Patent number: 6395335
    Abstract: A filling squeegee and a scraping squeegee are provided in a printing apparatus. The filling squeegee is moved without contacting a surface of a mask in order to fill a solder paste into openings of the mask. Unnecessary solder paste on the surface of the mask is scraped by the scraping squeegee. The solder paste is prevented from being improperly filled in or scraped from the openings even if a speed of the squeegee is increased, so that the solder paste can be printed stably on circuit board.

  • Patent number: 6379754
    Abstract: When bearing layers are producing by thermal coating the coating flame causes oxidation of a part of the coating material. To reduce this oxide formation and especially to lower the formation of oxide clusters in the layer a gas stream is projected next to the burner flame with an oxygen content lower than that of air. Preferably a gas with nitrogen ≧99% is used for the gas stream and as cooling gas for the burner. The method disclosed provides a bearing layer for a connecting rod eye. The large connecting rod eye is subjected to pre-spindle trimming, cracking and further spindle trimming to the coating tolerance, sandblasted and plasma coated with an aluminum bronze to produce a microporous layer. At the start of plasma spraying the plasma layer is deposited at a high temperature, which results in good adhesion of the plasma layer to the material of the connecting rod eye and low porosity of the plasma layer.

  • Patent number: 6352740
    Abstract: A method of coating an inner face of a weapon barrel with a coating material includes the following steps: introducing the coating material as a component in sheet or foil form into the weapon barrel; positioning the component in the weapon barrel such that a first face of the component is oriented toward the inner face of the barrel and a second face of the component is oriented away from the inner face of the barrel; maintaining an annular clearance between the inner face of the barrel and the component; providing the second face of the component with an explosive; and detonating the explosive for hurling the coating material of the component against the inner face of the barrel for effecting a cold welding between the coating material and the inner face of the barrel.

    Abstract: A process of coating a crown wall of at least one raised part of an extrusion screw which includes the following stages: a metal bead of hardness D1 is deposited on and in proximity to at least one edge of the crown part of each raised part to be coated, said bead occupying only a fraction of the width of said crown part; a second material of hardness D2 is then deposited on the rest of the uncoated crown part, said hardness D2 being significantly different from hardness D1; the deposits made in the preceding stages are ground in order to obtain the profile and the dimensions of each raised part on the screw.

  • Patent number: 6342276
    Abstract: A very fine pixel pattern can be formed by first screen printing a conductive paste and electron-emitting carbon paste material in sequence before removing a predetermined portion of the screen-printed layers simultaneously such that remaining portions become a fine pixel pattern. This method not only enables fine pixel pattern formation but also provides an electrode/emitter structure that increases electron emission. Furthermore all these improvements can be made with less manufacturing time and cost.

  • Patent number: 6340500
    Abstract: A method for improving the thermal fatigue life of a thermal barrier coating (TBC) deposited on an aluminide bond coat through a process by which the surface morphology of the aluminide bond coat is modified to eliminate or at least reduce oxidation and oxidation-induced convolutions at the alumina-bond coat interface, as explained more fully below. The bond coat is deposited to have generally columnar grains and grain boundary ridges at its surface, and is then peened at an intensity sufficient to flatten at least some of the grain boundary ridges, but insufficient to cause recrystallization of the bond coat when later heated, such as during deposition of the thermal barrier coating. In so doing, the original surface texture of the bond coat is altered to be smoother where the grain boundaries meet the bond coat surface, thereby yielding a smoother bond coat surface where the critical alumina-bond coat interface will exist following oxidation of the bond coat.

  • Patent number: 6306458
    Abstract: A process for reclaiming aluminum alloy donor from a vapor phase deposition process used to form a diffusion aluminide coating on a component, such as the high-temperature superalloy components of gas turbine engines. The process generally entails recycling a particulate aluminum alloy donor material that, as a result of having been used as the donor material for depositing a diffusion aluminide coating on an article by vapor phase deposition, particles of the donor material comprise an aluminum alloy core encased in an aluminum-depleted shell. The process generally entails tumbling the donor material in a manner that removes the aluminum-depleted shell, followed by sieving the donor material to remove shell fragments and undersized particles.
