摘要： An automotive engine valve stem, engine valve and method of producing both. The valve includes a head and a stem joined to the head. Lightweight, high-temperature materials, such as titanium-based materials may be used to make up at least a the majority of the valve. These materials are combined with fabrication techniques that may vary between the head and the stem, where at least a part of the valve is made by dynamic magnetic compaction. While a majority of the stem may be made from a titanium-based powder material, its tip may be made of a high strength hardened material, such as a steel alloy. The valve head may be made by single press and sintering, double press and sintering, forging and machining, forging and sintering, and dynamic magnetic compaction and sintering.

摘要： A cast iron cylinder liner for an engine has a body with a radial upper flange and a generally cylindrical wall extending axially from an inner portion of the flange. An arcuate fillet is formed at a juncture between the upper flange and an exterior of the cylindrical wall. To strengthen the juncture of thin wall liners, for example with wall thickness less than 2.5 mm, a portion adjacent the fillet is laser hardened to a selected depth of the wall, thus increasing resistance to stresses created in the wall when the liner is installed and operating in an engine.

摘要： A camshaft journal and method of producing the same. The method uses dynamic magnetic compaction in conjunction with austenitic manganese steel powder metal precursors. Journals formed along the camshaft are configured to cooperate with complementary bearing surfaces, and can be used in cooperation with one or more sensors such that the journal does not magnetically interfere with signals travelling to such sensors. The journals may also be subjected to machining, sintering or both once the dynamic magnetic compaction has been completed.

摘要： A method of forming a fluid barrier over a powder metal part. The method includes providing a molded powder metal part and applying a fluid impenetrable material to a designated portion of the molded powder metal part to form a molded powder metal complex. Thereafter, the method includes sintering the molded powder metal complex to where the fluid impenetrable material and the designated portion of the molded powder metal part at least partially integrate. Further, the method includes cooling the molded powder metal complex such that the fluid impenetrable material forms a fluid barrier over the designated portion of the molded powder metal part. The method may further include anodizing the fluid impenetrable material at least partially integrated with the designated portion of the molded powder metal part and forming the fluid barrier over the designated portion so as to increase wear resistance thereof.
