Abstract: A device and method for transferring filtered molten metal to a die casting mold. The device and method include a casting filtration system that includes a funnel and a continuously replaceable filter placed fluidly between a molten metal source and a casting mold. Both the funnel and filter are automatically moved into cooperation with a molten metal receptacle such as a shot sleeve prior to each casting operation, and then automatically moved out of the way so that pressurization of the filtered molten metal may take place in the receptacle. In addition, the filter may be formed on a continuous strand such that indexed movement of the strand will advance the used portion of the filter out of the way to make room for a new unused filter portion that will be ready for a subsequent repeated casting operation.

Abstract: A method of manufacturing an aluminum alloy cylinder head includes providing a precision sand core and mold assembly, a liquid aluminum alloy delivery system, and a mold manipulator system. The precision sand core and mold assembly is disposed in the mold manipulator system and the liquid aluminum alloy delivery system includes an in-furnace ultrasonic actuator and a launder tube having at least an ultrasonic actuator. The liquid aluminum alloy delivery system is sealed to the precision sand core and mold assembly and provides liquid aluminum alloy into a gating system of the precision sand core and mold assembly. The precision sand core and mold assembly is rotated approximately 180°. The precision sand core and mold assembly is vibrated.

Abstract: A method of making an aluminum alloy containing zirconium includes heating a first composition including aluminum to a first temperature. The first temperature is greater than or equal to a liquidus temperature of the first composition. The method further includes adding a second composition including a copper-zirconium compound to the first composition. The method further includes decomposing at least a portion of the copper-zirconium compound into copper and zirconium. The method further includes forming a third composition by dissolving at least some of the copper from the decomposing in the aluminum of the first composition. The method further includes cooling the third composition to a second temperature to form a first solid material. The second temperature is less than or equal to a solidus temperature of the third composition. The method further includes heat treating the first solid material to form the aluminum alloy containing zirconium.

Abstract: A method of making an aluminum alloy containing zirconium includes heating a first composition comprising aluminum to a first temperature of greater than or equal to about 580° C. to less than or equal to about 800° C. The method further includes adding a second composition including a copper-zirconium compound to the first composition to form a third composition. The copper-zirconium compound of the second composition has a molar composition of greater than or equal to about 41% zirconium to less than or equal to about 67% zirconium and a balance of copper. The method also includes solidifying the third composition at a cooling rate of greater than or equal to about 0.1° C./second to less than or equal to about 100° C./second to a second temperature less than or equal to a solidus temperature and decomposing the copper-zirconium compound at a third temperature of less than or equal to about 715° C.

Abstract: A composite thermal barrier coating (TBC) may be applied to a surface of components within an internal combustion engine. The composite TBC provides low thermal conductivity and low heat capacity insulation that is sealed against combustion gasses. The composite TBC includes three layers, bonded to one another, i.e., a first (bonding) layer, a second (insulating) layer, and a third (sealing) layer. The insulating layer is disposed between the bonding layer and the sealing layer. The bonding layer is bonded to the component and to the insulating layer. The insulating layer includes hollow microspheres that are sintered together to form insulation that provides a low effective thermal conductivity and low effective heat capacity. The sealing layer is a thin film that is configured to resist the high temperatures, present within the engine. The sealing layer is impermeable to gasses and presents a smooth surface.

Abstract: A method of transferring molten metal to a die casting mold is disclosed. The method includes providing a ladle with a dip well and a dispensing nozzle having a fluid metal filter formed therein as well as providing a receptacle fluidly between the ladle and the mold. Further the method includes delivering the molten metal from the ladle to the receptacle by positioning an exit face of the dispensing nozzle over the receptacle and rotating the ladle such that the exit face of the dispensing nozzle is repositioned proximal the bottom of the receptacle and conveying the molten metal that has been delivered to the receptacle into a mold cavity that is placed in fluid communication therewith.

Abstract translation: 一种用于将过滤的熔融金属转移到压铸模具的装置和方法。 该装置和方法包括铸造过滤系统，其包括漏斗和可流动地置于熔融金属源和铸模之间的可连续更换的过滤器。 在每个铸造操作之前，漏斗和过滤器都自动地与熔融金属容器（例如喷射套筒）配合，然后自动移出，使得过滤的熔融金属的加压可能发生在容器中。 此外，过滤器可以形成在连续的股线上，使得股线的分度运动将使过滤器的使用部分前进，以便为将用于随后的重复铸造操作准备好的新的未使用过滤器部分腾出空间 。
