Abstract
The invention relates to a method of producing a slide bearing element (1) according to which a sliding layer (6) is produced on a support element (4) by vapour-phase deposition, if necessary after the insertion of at least one intermediate layer, wherein the sliding layer (6) comprises an aluminium matrix, which in addition to aluminium contains bismuth as a main component and possibly copper and also impurities of the elements arising during production. By means of the vapour-phase deposition of at least one element, the melting point of which is at least 950.degree. C. higher than that of the bismuth and/or by applying a bias-voltage to the support element the bismuth-nuclear density is increased.
