  • Patent number: 5807428
    Abstract: The present invention relates to a composition for coating internal surfaces of an airfoil, particular high pressure temperature airfoils such as vanes and blades. The composition includes a dry composition consisting essentially of from about 2.5 wt % to about 7.0 wt % aluminum fluoride, from about 5.0 wt % to about 20 wt % of a chromium-aluminum powder, and from about 75 wt % to about 92.5 wt % Al.sub.2 O.sub.3. The dry composition is mixed with water and a cellulose compound to form a slurry which is thereafter injected into the airfoil. The coating compositions of the present invention are valuable in that they are capable of forming an oxidation and corrosion resistant coating on the internal surfaces of the airfoil simultaneously with the formation of an exterior corrosion and oxidation resistant coating. A process for simultaneously forming corrosion and oxidation resistant coatings on the interior and exterior surfaces of an airfoil is described herein.

  • Patent number: 5806487
    Abstract: A fuel injection pump unit consists of a fuel injection pump (1), in which a quantity-determining member (6) is set by an actuator (13), its position being detected by a position sensor (15), and of a control unit (2) which calculates an injection quantity (M) and from that, using a stored ignition characteristic (33), determines a set value (.beta..sub.set) for the quantity-determining member (6). To provide a simple and precise calibration of the pump unit with minimal complexity, there are two adjustable stop faces (21, 22) which delimit the travel of the quantity-determining member (6) and in each case define a position of the quantity-determining member (.beta..sub.1, .beta..sub.2) commensurate with a certain measured injection quantity (M.sub.1, M.sub.2), in each case at a certain distance (k.sub.1, k.sub.

  • Patent number: 5804258
    Abstract: In a process for coating a substrate surface with a layer of inorganic material, the inorganic material is vaporised in a vacuum chamber evacuated to at least 10.sup.-3 mbar by bombarding with an electron beam from a high voltage electron-beam gun and deposited on the substrate surface. Gas discharging is created between the point of incidence (A) of the electron beam on the inorganic material to be vaporised and an anode such that the electrostatic charge created by the high voltage electron-beam gun flows off via the anode. This way damage to the substrate, which may arise as a result discharging phenomena, can be effectively avoided.

  • Patent number: 5799721
    Abstract: For the continuous remelting of metals--in particular steels and Ni-- Co-base alloys--in a short, downwardly open water-cooled chill mold (20) for producing an elongate casting portion (26) the latter is produced either by continuous or stepwise withdrawal from the chill mold (20) or when the elongate casting portion (26) is stationary by corresponding lifting movement of the chill mold (20). In order to ensure on the one hand a sufficiently high and thus economical smelting rate and on the other hand a high level of quality in respect of the remelted elongate casting portions (26), the cross-sectional area of the smelting-off electrode (16) should be at least 0.5 times the cross-sectional area of the remelted elongate casting portion (26) and the smelting-off rate should be so adjusted that it corresponds to between 1.5 and 30 times the equivalent elongate casting portion diameter (D.sub.eq) calculated from the circumference (U) of the casting cross-section, in accordance with the relationship:D.sub.eq =U/.
