Testing Characteristics

• Unidirectional sliding at 100 to 300 rpm (0.27 to 8 m/s)
• Hemispherically-tipped pin loaded against disk through dead weights
• Friction force continuously measured with load cell
• Specimen heated with low-frequency induction coil up to 900 °C
• Disk surface temperature measured on disk wear track 90° ahead of pin
• Tests can be performed in controlled atmosphere (inert, oxidizing, etc.)
