Radioactive tracer technology (RATT^®) techniques at Southwest Research Institute (SwRI) provide cost-effective, accurate, real-time data, detecting minute wear changes without disassembly and physical inspection, to study component wear during transient and steady-state conditions.
 

Past RATT^® Projects

Past radioactive tracer measurement projects include:

• Measuring piston ring wear associated with changes in engine speed, load, and operating temperature; fuel and lubricant quality and type; fuel dilution in oil, and internal and external contamination.

• Measuring fuel injector wear associated with component metallurgy, fuel quality, and contaminant level.

• Evaluating diesel engine cylinder liner wear correlating to liner design, material, and lubrication.

• Investigating engine wear sensitivity to fuel, lube oil, and air filtration.

• Measuring engine wear associated with dust contamination to determine relationships between component wear, particle size, and filtration level.

• Studying filter performance and filter test procedures using irradiated standardized test dusts.

• Comparing component wear for an engine operating alternately on natural gas and gasoline.

• Measuring engine wear under advanced combustion system operation.

• Measuring turbocharger bearing wear.

• Measuring component wear in a large hydraulic pump.

• Measuring prosthetic material wear (hip joint components).

• Measuring crude oil corrosivity.

• Measuring injector wear in response to fuel lubricity.
