New methodology for chemical characterisation of interaction coating-lubricant

A modular vacuum doser has been designed and manufactured to dose a reproducible film of lubricant on a previously well characterised and clean substrate. The sample can be subsequently transferred to an analysis chamber. The lubricant can be deposited from atmospheric to 10-6 mbar pressure. Thermal Desorption Spectroscopy can be performed in situ (previously to transfer) and simultaneously to deposition (if pressure is 10-6 mbar). The sample transfer system allows easy and fast transport of the sample under vacuum and clean conditions to an attached analysis system of X-ray Photoelectron Spectroscopy (Electron Spectroscopy for Chemical Analysis). The coating-lubricant interaction can be studied practically in situ. These in-situ measurements can be compared with other ex-situ (atmospheric pressure) analysis such as Attenuated Total Reflection Fourier Transform Infrared Spectroscopy.
