I would suggest x-ray photoelectron spectroscopy (ESCA or XPS) as an alternative for further study. The technique will analyze thin films (20 A) and detection limits are good enough (about 0.1%). In addition, XPS will give you information about the compounds present, e.g. whether the oxygen is aluminum oxide, aluminum hydroxide, etc. Good Luck.
In this work, a vision-based approach has been developed to detect the onset of chipping in aluminum oxide ceramic cutting tools during the dry turning of AISI 01 oil-hardening tool steel.
