  • JOINING OF HIGH WEAR RESISTANT AND BASE MATERIALS
    Publication number: 20240139859
    Abstract: Linear friction welding is used to join dissimilar materials, namely a first workpiece formed of a high wear resistant material and a second workpiece formed of a base material. A compressive force is applied and a friction force is generated between the first and second workpieces. A solid-state joint is formed between the first and second workpieces. The high wear resistant material can be a tool steel, and the base material can be a low alloy steel or a carbon steel. The composite assemblies can be used for mining wear applications.

  • Low friction end feeding in tube hydroforming
    Patent number: 8910500
    Abstract: An end plunger for end feeding during a hydroforming process (such as tube hydroforming) has at least one releasable seal. The effect of the releasable seal is that it avoids pressurizing the blank in a nip area, thereby reducing friction and wear, and allowing increased end feeding with a given end feeding force. The releasable seal may be actuable, for sealing or releasing. The plunger may be modular or monolithic. A kit and method may incorporate the end plunger.
