Advanced Materials Research LaboratoryCorrosion and Tribology

AMRL offers a comprehensive suite of tribological testing capabilities to support fundamental research and industrial problem-solving in wear, friction, and surface degradation. Our facilities enable detailed evaluation of material performance under conditions representative of service environments, including both corrosive and mechanical wear mechanisms.

Our capabilites include dynamic corrosion and tribocorrosion testing to investigate the combined effects of mechanical wear and corrosive environments, dry and lubricated pin-on-disc testing using systems such as the TRB3 tribometer to quantify friction and wear under controlled loads and speeds, and sand erosion testing using an impinging jet rig to assess resistance to high-velocity particulate impact. In addition, AMRL operates a salt spray chamber for accelerated corrosion testing and a Multiplex sand/wheel abrasion tester for evaluating abrasive wear performance.

Salt spray chamber

  • Accelerated corrosion testing under controlled salt spray environments
  • Neutral Salt Spray (NSS) testing in accordance with ASTM B117 and ISO 9227
  • Precise control of chamber temperature, salt solution concentration, spray rate, and exposure duration
  • Assessment of corrosion resistance, coating integrity, and surface degradation
  • Suitable for comparative performance evaluation of coatings, surface treatments, and base materials
  • Capable of long-duration exposure testing for durability and lifetime studies

Multiplex Sand/Wheel Abrasion Tester

  • Quantitative abrasive wear testing using sand-rubber wheel and wheel abrasion configurations
  • Testing conducted in accordance with ASTM G65 and related wear standards
  • Controlled application of normal load, wheel speed, and abrasive feed rate for repeatable testing
  • Measurement of mass loss, wear rate, and relative abrasion resistance
  • Suitable for bulk materials, coatings, and surface-engineered systems
  • Enables comparative assessment of material performance under simulated service conditions
