摘要： A powder metal component which has a powder metal composition formed into a cylinder, wherein the cylinder includes a wall thickness and a length, and a ratio of the length to the thickness is relatively high such that conventional compaction methods are difficult to use. The powder metal composition includes approximately between 85% and 99% sponge iron powder, approximately between 0.1% and 2.0% graphite, and approximately between 0.1% and 2.0% ethylene bis-stearamide wax. The powder metal component can be manufactured using an apparatus which includes a hard material core rod, and a shaped elastic die configured to circumscribe the core rod, or conversely, an apparatus with a shaped elastic core rod and a hard die. In the case of the former, the shaped elastic die can have an inner contour wherein a longitudinal load on the shaped elastic die radially compresses the powder metal to the desired shape and density distribution, hi the latter, longitudinally compressing the core rod radially compresses the powder metal to the desired shape and density distribution. An ejection punch can be made flush with the liner an pressure on the elastic die relieved prior to ejection to promote end integrity, the elastic die can be compressed alone or simultaneous with axial compression of the powder metal or a collet can be used to radially compress the elastic die using axial motion.
摘要翻译：一种粉末金属组分，其具有形成为圆筒的粉末金属组合物，其中所述圆筒包括壁厚和长度，并且长度与厚度的比率相对较高，使得常规的压实方法难以使用。粉末金属组合物包括约85％至99％的海绵铁粉，约0.1％至2.0％的石墨和约0.1％至2.0％的亚乙基双硬脂酰胺蜡。粉末金属成分可以使用包括硬质材料芯棒和被配置为围绕芯棒的成形弹性模具或相反地具有成形弹性芯棒和硬模具的装置的装置来制造。在前者的情况下，成型的弹性模头可以具有内部轮廓，其中成形弹性模具上的纵向载荷将粉末金属径向地压缩到期望的形状和密度分布。在后者中，纵向压缩芯棒径向地压缩粉末金属到所需的形状和密度分布。喷射冲头可以与衬垫齐平，弹性模具上的压力在排出之前释放以促进端部完整性，弹性模头可以单独压缩或与粉末金属的轴向压缩同时压缩或者可以用于径向压缩弹性模具使用轴向运动。

摘要： A powder metal cylinder liner with a ratio of the length to the wall thickness greater than 12 made of at least two end to end cylinder liner pieces with each piece having a ratio of the length to the wall thickness of less than 20. The powder metal composition includes approximately between 85% and 99% sponge iron powder, approximately between 0.1% and 2.0% graphite, and approximately between 0.1% and 2.0% ethylene bis-stearamide wax. The cylinder liner pieces can be made using conventional powder metal compaction and sintering processes.

摘要： A high performance main bearing cap has particular surfaces densified for improved fatigue crack resistance. The surfaces densified are the bolted face (F) inside of a perimetral margin and outside of bold head interface areas around the main bolt holes (B), the surfaces of the main bolt holes and the side bolt hole threads (S). Preferred methods of densification are single needle programmable pattern peening of the bolted face peened area, over-burnishing of the bolt holes, and forming the threads rather than cutting them for the side bolt threads.
摘要翻译：高性能主轴承盖具有致密化的特定表面以提高耐疲劳龟裂性。密封的表面是围绕主螺栓孔（B），主螺栓孔和侧螺栓孔螺纹（S）的表面的周边边缘内部的螺栓面（F）和外侧的粗体头部界面区域。优选的致密化方法是螺栓孔喷丸处理区域的单针可编程图案喷丸处理，螺栓孔的过度抛光以及形成螺纹而不是将其切割成侧螺栓螺纹。

摘要： The present invention provides a PM main bearing cap, and its precursor compact, with an undercut breathing window that is formed during a compaction process. By fabricating the undercut during the compaction process, the invention eliminates the need for a secondary machining operation to form the undercut feature in the bearing caps.
