    • A diecast pocket plate or member having a sacrificial surface layer or portion is provided. The member is formed as a unitary die-casting from a die-casting alloy strengthened by an alloying material in a die-casting process. The diecast member includes a coupling face having a pocket which is sized and shaped to receive and nominally retain a locking member that moves in the pocket during an overr condition of an engageable coupling assembly. The diecast member also includes a relatively hard base portion including particles of the strengthening alloying material of the die-casting alloy. The diecast member further includes a plurality of surface portions which define the pocket. At least one generally vertical surface portion of the surface portions is soft relative to the hard base portion and is substantially devoid of the particles of the alloying material so that the at least one generally vertical surface portion wears.
    • 提供具有牺牲表面层或部分的压铸袋或板。 该构件由压铸过程中由合金材料强化的压铸合金形成为单一压铸件。 压铸构件包括具有凹口的联接面,该凹槽的尺寸和形状适于容纳和标称地保持在可接合联接组件的超越状态期间在口袋中移动的锁定构件。 压铸构件还包括相对硬的基部,其包括压铸合金的强化合金材料的颗粒。 压铸件还包括限定袋的多个表面部分。 表面部分的至少一个大致垂直的表面部分相对于硬质基部是柔软的,并且基本上没有合金材料的颗粒,使得至少一个大致垂直的表面部分在(例如,牺牲)期间磨损或变形 在超越状态期间,锁定构件与所述至少一个大致垂直的表面部分的接触。
