Abstract
An effective cleaning procedure for ball bearings was investigated which has a low possibility for environmental pollution. Specimens of bearing steel protected by an anti-rust oil containing barium sulfonate and zinc sulfonate were tested. For detergents, combination of ethanol and a commercially-available synthetic detergent was used, which was considered lower pollutive among organic detergents. Instead of synthetic detergents, a weak alkaline detergent containing a potassium fatty acid (27 % solution), much lower pollutive, was used also for the tests. An X-ray photoelectron spectroscopy (XPS) analysis was performed to evaluate their effectiveness. Results showed that a synthetic detergent ultrasonic cleaning followed by an ethanol completely cleaned a mirror-finished surface, whereas not a turned one (R{sub max}: 20 micron m). It was additionally determined that the potassium fatty acid solution exhibited superior cleaning capability when compared to organic solvents including trichloroethylene, although being inferior to the alkaline detergents. 5 refs., 7 figs., 3 tabs.
