摘要: To produce a steel liner (10) for a cylinder (112) of an internal combustion engine, a tubular preform (50) of steel is subjected to a flow forming procedure which transforms it into a semi-finished liner (56) having a configuration that corresponds closely to the configuration desired for the cylinder liner. The flow forming process achieves a near-net shape such that only minimal amount of subsequent machining is required to transform the semi-finished liner (56) into the final shape for the cylinder liner (10).

摘要: A method of forming a component includes heating the component to a burnishing temperature above 500 degrees Fahrenheit, and burnishing a surface of the component while the component is at the burnishing temperature to densify the surface. The burnishing process at an elevated temperature may be integrated into other processes, such as the sintering or heat treating processes.
