    Abstract: The invention relates to a method for manufacturing a surface-alloyed cylindrical, partly cylindrical or hollow cylindrical structural member where in the zone of incidence of the energy beam there is formed a locally bounded melting bath with a heating and melting front, a solution zone and a solidification front. At the side of the energy beam the hard material powder is deposited via a conveyor device in the direction of gravity and is supplied co-ordinated with the feed movement of the workpiece in a width which corresponds to the width of the linear focus and a layer height of 0.3-3 mm is thereby produced. The hard-material powder supplied to the workpiece surface in the heating front of the melting bath is heated by an energy beam at a wavelength of 780-940 nm and in contact with the liquefied matrix alloy the powder is immediately dissolved in the melting bath. Convection is produced in the solution zone by the energy beam having a specific power of at least 104 W/cm2, so that the homogenisation process in the melting zone is accelerated, where the linear focus acts on the solution zone until the hard material powder is uniformly distributed in the melting bath. In front of the energy beam the uniformly distributed powder material, which has gone into solution metallurgically in the solution zone, is subjected to directional solidification in the solidification front at a high cooling rate of 200-600 K/s at a feed rate of 500-10,000 mm/min. The invention also relates to a device for implementing the method, consisting of a workpiece clamping device, on which a workpiece is aligned and clamped above index holes and/or above working surfaces, onto whose surface a powder supply and a focusable beam from a beam head are directed.

    Abstract: An apparatus for placing particles onto a substrate, methods for using the apparatus to deposit particles on a substrate and substrates prepared using the apparatus are disclosed. The apparatus includes a rotary screen, a blade disposed for directing and urging the particles through the screen, and a sheet mounted in a position to receive the particles from a feeder and deliver the particles to the rotary screen substantially across the blade. The apparatus can include a frame on which a rotary screen is rotatably mounted and a feed system disposed within and extending substantially along the length of the screen for distributing the particles. The apparatus can optionally include a vacuum means, an anti-static means and/or collection pans for handling stray particles. The screen can include a series of openings in the form of a pattern, and can be used to place particles in a pattern in register with a design or pattern on a substrate as the substrate passes under the openings in the screen.

    Abstract: A method for damping vibration of a substrate comprises the step of applying a liquid material onto the substrate in an ambient environment, wherein, after application to the substrate, the material cures substantially instantaneously in the ambient environment. The damping composition usable therefor comprises a resin component and an isocyanate component. The resin component includes a polymer(s) for imparting tensile strength, hardness and flexibility; an optional chain extender(s) for imparting tensile strength, weatherability, flexibility, adhesion to specific substrates, and hardness; and an optional filler for imparting hardness, flexibility, and specific noise, vibration and harshness blocking characteristics to the after-application, cured surface. The isocyanate component of the composition includes an isocyanate quasi-prepolymer(s) based on a uretonimine modified MDI and a high molecular weight polyether polyol having an isocyanate equivalent content of 15.8% and a 2,4null-isomer content of less than about 15%; and an optional plasticizer(s) for imparting flexibility.
