摘要： A method and apparatus for filling a cavity with powder wherein a pipe having holes for discharging gas is disposed in a powder box and gas is discharged into the powder in the powder box as the powder enters the cavity so that particles of the powder are movable relative to each other. Due to the gas discharge, the powder can enter the cavity smoothly without whirling up in the cavity and settling unevenly, so that a filling time period is shortened and a particle size distribution in the cavity is uniform.

摘要： This invention provides a method of forming a powder compact which can produce a high density compact under a high pressure and at the same time can reduce pressure for ejecting the compact from a die.This method comprises the application step of applying a higher fatty acid lubricant to an inner surface of a heated die, and the compaction step of filling metal powder into the die and compacting the metal powder under such a pressure as to force the higher fatty acid lubricant to be chemically bonded with the metal powder and form a metallic soap coating. Since the metallic soap coating is formed between the die and a compact, friction force between the die and the compact is decreased and ejecting pressure can be remarkably decreased despite of compaction with high pressure. Besides, a high density compact can be obtained owing to the compaction with high pressure.

摘要： A process for producing a sliding member employs a base material having a covering surface and pores, and a layer material comprising a constitutive component for reacting with a constitutive component of the base material. Initially, the layer material comes into contact with at least part of the covering surface of the base material. Next, the both are heated to the sintering temperature of the base material. Thus, a molten liquid occurs at the boundary between the base material and the layer material. Since the solidus temperature of the molten liquid increases with the reaction proceeding, the molten liquid can solidify early to seal the pores at the covering surface of the base material early. Therefore, the layer material remains on the covering surface of the base material, the remaining layer material comes to constitute a sliding surface.
摘要翻译： 用于制造滑动构件的方法采用具有覆盖表面和孔的基材，以及包含用于与基材的构成成分反应的组成成分的层材料。 最初，层材料与基材的至少一部分覆盖表面接触。 接下来，将两者加热至基材的烧结温度。 因此，在基材和层材料之间的边界处发生熔融液体。 由于熔融液的固相线温度随着反应进行而增加，所以熔融液体可以提早凝固，以便早期密封基材的覆盖表面的孔。 因此，层材料残留在基材的覆盖面上，残留的层材料构成滑动面。
