Air conditioner compressor fluids have to prevent friction and wear under elevated gas pressure. Standard Pin&Vee Block tests with gas 'bubbling' through the lubricant do not correlate with field behaviour, especially with CO2 as the cooling medium. Another simulation with pressurized gas is needed. We selected the Falex Block on Ring configuration, as it also recreates the line contacts and is able to work at higher speed than the Pin&Vee block machine.
The reliability of industrial equipment, transportation systems, nuclear and conventional power plants etc. can be significantly influenced by surface phenomena such as corrosion and wear. With the increasing pressure on development time and the need for higher performance, there is also an increasing need to measure and quantify the degradation phenomena faster and better. In this perspective, nuclear activation technology - as already used in engine testing- can provide accurate in-situ measurement and precise monitoring of wear, mass transfer, corrosion and erosion.
Polymeric materials are used more and more as cage material for light weight bearing applications, but thermoplastic materials suffer from PV limits. At high speeds, the polymer may melt easily under light loads. Thermoset resins don't have this limit, but may still disintegrate under higher temperatures. In this method, we can apply high speeds and variable loads, to explore the limits of thermosets.
