    Abstract: A light-weight, high-strength compressor component is formed via additive manufacturing that has controlled stiffness and/or deflection levels. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprises the lattice structure in the body portion of the light-weight, high-strength compressor component. The lattice structure may be used to globally or locally control stiffness and/or deflection levels of the compressor component. Additive manufacturing provides flexibility in forming compressor components with desirably improved strength-to-weight ratios while exhibiting high levels of control over stiffness and/or deflection. Methods of making such compressor components via additive manufacturing processes are also provided.

    Abstract: Methods for making a tribological bearing wear surface for a compressor component are provided. Such methods involve semi-solid metal casting, where an admixture of solid lubricant particles and a metal alloy material is heated to melt the metal alloy material, while the lubricant particles remain in a solid phase. The alloy material and solid lubricant have substantially different densities. The metal alloy material may be a copper, iron, or aluminum alloy, for example. The method further comprises mixing and cooling the admixture to form a semi-solid slurry admixture. Next, the method comprises introducing the semi-solid slurry admixture into a die. Finally, the semi-solid slurry admixture in the die is solidified to form a solid component having the solid lubricant particles homogenously distributed within a metal alloy material matrix, thus forming a metal matrix composite. Compressor components made from such methods are also provided.

    Abstract: Scroll members for scroll compressors made from one or more near-net shaped powder metal processes, either wholly or partially fabricated together from sections. In certain variations, the involute scroll portion of the scroll member has a modified terminal end region. The terminal end region may include an as-sintered coupling feature comprising a tip component that forms a contact surface for contacting an opposing scroll member during compressor operation. The tip component can be a tip seal or a tip cap received by the as-sintered coupling feature. The tip cap may be sinter-bonded or otherwise coupled to the terminal end region. In other variations, a terminal end region may comprise a second material including a tribological material that forms a contact surface. Methods of making such scroll members for scroll compressors are also provided.

    Abstract: A light-weight, high-strength compressor component having at least one fluid delivery feature that is formed via additive manufacturing is provided. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprising the lattice structure has at least one fluid delivery feature for permitting fluid flow through the body portion of the light-weight, high-strength compressor component. The fluid delivery feature may be a flow channel, a fluid delivery port, a porous fluid delivery feature, or the like that serves to transfer fluids through the component, such as refrigerant and/or lubricant oils. Methods of making such compressor components via additive manufacturing processes are also provided.
