Abstract
The invention relates to a method of manufacture of a scroll compressor (1), in particular for pretreatment for the coating of areas in contact with one another during operation of the scroll compressor (1). The scroll compressor (1) is developed with a non-movable spiral (3) with a base plate (3a) and a spiral-form wall (3b) extending from one side of the base plate (3a), as well as with a movable spiral (4) with a base plate (4a) and a spiral-form wall (4b) extending from a front side of the base plate (4a). The spirals (3, 4) are developed out of a basis material.

A method of manufacture of a scroll compressor, in particular of the pretreatment for the coating of areas in contact with one another during operation of the scroll compressor, wherein the scroll compressor is developed with a non-movable spiral with a base plate and a spiral-form wall, extending from one side of the base plate, as well as with a movable spiral with a base plate and a spiral-form wall extending from a front side of the base plate and the spirals are developed out of a basis material, the method comprising the following steps:
- degreasing of an area to be coated of a surface of one of the spirals,
- etching of the area using an alkaline etching agent,
- etching of the area using an acidic etching agent,
- first etching of the area using a zincate etchant,
- application of a zincate layer as intermediate layer onto the area to be coated,
- further etching of the area using a zincate etchant, and
- coating of the treated area using a coating material closing off the surface.
A scroll compressor for the compression of a gaseous fluid, comprising
- a non-movable spiral with a base plate and a wall developed in the form of a spiral extending from one side of the base plate, and
- a movable spiral with a base plate and a wall developed in the form of a spiral extending from one side of the base plate with a free front face oriented distally to the base plate,
- wherein the base plates are disposed oriented with respect to one another such that the wall of the non-movable spiral and the wall of the movable spiral interleave, and the spirals are developed out of a uniform basis material, wherein the front face of wall of the movable spiral is sealingly disposed adjacently directly against the base plate of the non-movable spiral, wherein the front face of wall of the movable spiral is developed with a coating comprised of nickel.
