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° C. higher than that of the bismuth and/or by applying a bias-voltage to the support element the bismuth-nuclear density is increased.

Abstract: The invention relates to a bar-shaped magnetron-sputter cathode arrangement having an internal, cooled permanent magnet system and a carrier tube for the target. It is provided according to the invention that at least one thermal contact layer (38) is disposed between the carrier tube (36) and the target, which consists of one or more ring(s) (37, 37', 37") shrunk, especially interchangeably, onto the carrier tube (36). During sputtering the cathode (6) and the surface to be sputtered can be subjected to a mutual relative motion in the longitudinal direction of the cathode (6), for which purpose an adjusting element is provided. The magnets (31) are disposed inside the carrier tube (36) with the magnetic fields having alternately opposing directions in the longitudinal direction of the carrier tube (36). They possess cylindrical or polygonal lateral surfaces and end faces (44) which are parallel and slope at an angle (.alpha.) to the longitudinal direction of the electrode (6) or shaft (30).
