METHOD OF MAINTAINING CONSTANT CLEARANCE

摘要

A method for reducing abrasion between interacting moving parts which comprises applying an anti-abradant element between said moving parts which anti-bradant element will increase in dimensional proportions upon exposure to oxidation, sulphation, nitration, carbonation and/or heat annealing whereby as the anti-abradant element is abraded, said dimensional proportions are increased whereby the spacing between said moving parts is maintained relatively constant.
