Embodiment Construction

[0032] Figure 1 to Figure 4 A device 10 according to the invention for the metallization of holes 3 in a workpiece 1 is shown. In the embodiment shown, the workpiece 1 is an engine block with 12 holes 3, which are cylinder bores, arranged in the workpiece 1 in two rows of 6 in a V-shaped arrangement.

[0033] The device 10 comprises a machine base 11 on which a housing 13 is arranged. A box-shaped housing 13 surrounds the loading station 12 and the processing station 14 with the coating device 29 .

[0034] On the machine base 11 is arranged a base frame 16 of a conveyor 20 for picking up workpieces 1 , which in the embodiment shown is designed as a rotary table 22 . A horizontal rotary table 22 driven in rotation about a vertical axis of rotation comprises two workpiece holders 23 opposite each other, each provided with a plate-like platform assembly 21 each carrying a workpiece 1 . Via the rotation unit 26, the platform assembly 21 with the workpiece 1 can be rotated cou...

Abstract

The invention relates to an installation and a method for the metallic coating of a workpiece using a coating device, said coating device comprising a displaceable coating lance, by which a metal plasma jet can be generated to create a coating of metal particles. According to the invention, it is provided that the coating device with the coating lance and a measuring device for measuring the coating thickness are jointly integrated in the installation, and that the coating device with the coating lance as well as the measuring device are enclosed by a housing.

Description

technical field [0001] The invention relates to a plant for the metal coating of workpieces using a coating device comprising a movable coating lance through which a metal plasma jet can be generated to form a coating of metal particles. [0002] The invention also relates to a method for the metal coating of workpieces using a movable coating lance, by means of which a metal plasma jet can be generated, by means of which a coating of metal particles can be formed on the workpiece. Background technique [0003] Especially in engine manufacturing, it is necessary to apply a special metal coating on the working surface of the cylinder bore to ensure sufficient friction and lubricating environment between the working surface of the cylinder and the cylinder piston. This applies in particular if the housing of the engine and the cylinder pistons are made of the same metal (eg aluminium). [0004] It is known from the descriptions DE 199 34 991 A1 or WO 2004 / 005575 A2 that a met...
