An experimental investigation on composite fretting mode

An apparatus for composite fretting tests on a steel ball opposite to the i nclined steel flat with different inclined angles (60 degrees and 45 degree s) have been carried out. During the tests, the maximum imposed loads were varied from 200 N to 400 N and 800 N at a constant loading speed of 12 mm/m in. Dynamic analysis in combination with microscopic examinations through o ptical microscopy, profilometery, and SEM have been performed. Composite fr etting behaviour has been analyzed and compared with the conventional frett ing. (C) 2001 Elsevier Science Ltd. All rights reserved.
