Abstract: The present invention relates to an aqueous lubricant composition for the lubrication of a stationary or mobile drive system, comprising at least: deionized water; at least one polyalkylene glycol; at least one antifreeze compound chosen from glycols, and at least one phosphorus compound. It also relates to the use of this aqueous lubricant composition for the lubrication and cooling of a stationary or mobile drive system.

Abstract: A metallurgic implantation apparatus of metal ions having a large emitting surface, a considerable flux and a controllable implantation depth comprises within an implantation chamber held in vacuo at least one vacuum arc ion source (1, 2, 3, 4) from which the ions (5) are extracted and projected onto a target plate (9) by means of an extraction and focusing electrode (6,7) and of an acceleration electrode (8) polarized at a very high and at a low voltage, respectively. The target plate (9) bombarded by the projection of ions emits a flux of secondary electrons, which are repelled by a suppression electrode (10) polarized negatively with respect to the target plate connected to ground.
