<Desc/Clms Page number 2>
In der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes eine Zylindertrommel einer Axialkolbeneinheit im Schnitt dargestellt. Die Zylindertrommel 1 ist mit Zylinderbohrungen 2 versehen und weist einen Steuerspiegel 3 auf, in dem Kanäle 4 munden, wobei jeder der Kanäle 4 in eine Zylinderbohrung 2 mündet. Die Innenseiten der Zylinderbohrungen 2 sind mit Aluminium-Oxyd-Schichten 2' und der Steuerspiegel ist mit einer Aluminium-Oxyd-Schicht 3'versehen. Zur Lagerung der Zylindertrommel 1 auf einem in der Zeichnung nicht dargestellten Achszapfen sind zentrisch in der Zylindertrommel 1 Bohrungen 5,6 und 7 angeordnet, deren Wände mit Aluminium-Oxyd-Schichten 5'. 6'und 7'versehen sind.
PATENTANSPRÜCHE :
1. Als Pumpe oder Motor verwendbare hydrostatische Arbeitseinheit mit Bauteilen, die aufeinander gleiten, von denen mindestens einer aus Aluminium oder einer Aluminium-Legierung besteht, dadurch gekennzeichnet, dass zumindest die Gleitflächen der aus Aluminium oder Aluminium-Legierung bestehenden Bauteile aus in einem vorzugsweise stark unterkühlten Spezialelektrolyten unter Einwirkung von Strom gebildeten Aluminium-Oxyd bestehen.

In the drawing, a cylinder drum of an axial piston unit is shown in section as an exemplary embodiment of the subject matter of the invention. The cylinder drum 1 is provided with cylinder bores 2 and has a control plate 3 into which channels 4 open, each of the channels 4 opening into a cylinder bore 2. The insides of the cylinder bores 2 are provided with aluminum oxide layers 2 'and the control plate is provided with an aluminum oxide layer 3'. To mount the cylinder drum 1 on a journal not shown in the drawing, bores 5, 6 and 7 are arranged centrally in the cylinder drum 1, the walls of which have aluminum oxide layers 5 '. 6 'and 7' are mistaken.
PATENT CLAIMS:
1. As a pump or motor usable hydrostatic working unit with components that slide on each other, of which at least one consists of aluminum or an aluminum alloy, characterized in that at least the sliding surfaces of the components made of aluminum or aluminum alloy in a preferably strong Supercooled special electrolytes under the action of electricity consist of aluminum oxide.
