摘要： A metal-based composite includes a metal matrix including aluminum as a major component, discontinuous alumina fibers buried in the metal matrix, mullite particles buried therein, and solid lubricant particles buried therein. The solid lubricant particles can be either graphite particles with a nickel layer formed on a surface thereof, or boron nitride cermet particles. By thus including the specific solid lubricant particles, the wear resistance of the metal-based composite can be improved, the wear of its mating parts can be reduced, and the friction coefficient between the metal-based composite and the mating parts can be inhibited from fluctuating. Hence, the metal-based composite can appropriately make aluminum-based internal combustion engines.

摘要： A composite aluminum member joining process. A chemical film including potassium and fluorine is formed on an aluminum member or a flux including potassium and fluorine is coated on an aluminum member. The coated aluminum member is buried together with a disposable pattern in a predetermined assembled state in a mold including molding sand. Then, molten aluminum alloy is poured into the mold, thereby molding an aluminum alloy cast member. The mold is decompressed through the molding sand, thereby expelling tar-like substances generated when the disposable pattern comes in contact with the molten aluminum alloy, burns and vaporizes, at least from the boundary surface between the disposable pattern and the molding sand to the molding sand disposed around the disposable pattern and preventing the tar-like substances from interposing between the aluminum member and the aluminum alloy cast member made from the molten aluminum alloy. Thus, the tar-like substances are drawn in by suction and expelled at least from the boundary surface between the disposable pattern and the molding sand to the molding sand disposed around the disposable pattern before they are deposited on the surfaces of the aluminum member. As a result, the tar-like substances do not interpose between the aluminum alloy cast member and the aluminum member coated with the chemical film or the flux. Therefore, the aluminum member and the aluminum alloy cast member are joined completely, because the effects of the chemical film or the flux have not been lost.
摘要翻译：复合铝构件接合工艺。在铝构件上形成包括钾和氟的化学膜，或者将包含钾和氟的焊剂涂覆在铝构件上。涂覆的铝构件以预定的组装状态与一次性图案一起掩埋在包括模型砂的模具中。然后，将熔融铝合金倒入模具中，从而模制铝合金铸件。模具通过型砂减压，从而排出当一次性模式与熔融铝合金接触时产生的焦油状物质，至少从一次性图案和型砂之间的边界表面燃烧和蒸发成型围绕一次性图案设置的砂，并防止焦油状物质插入铝构件和由熔融铝合金制成的铝合金铸造构件之间。因此，焦油状物质通过抽吸抽吸，至少从一次性图案和型砂之间的边界表面排出到在一次性图案周围设置的型砂，然后将其沉积在铝构件的表面上。结果，焦油状物质不会插入在铝合金铸件和涂有化学膜或焊剂的铝构件之间。因此，由于化学膜或焊剂的作用没有丧失，所以铝构件和铝合金铸件完全接合。
