Definitions
- the invention relates to a sliding and / or mating ring of a drive seal, comprising an angular cross-section body.
- DE 103 52 675 A1 discloses a mechanical seal and a method for producing the same.
- Trained as a drive seal mechanical seal consists of a metallic sliding and / or counter-ring, which is provided in the region of its tread with a wear protection layer, which is formed by embedded in the tread hard material particles.
- the sliding and / or counter ring should consist of light metal, in particular an aluminum alloy.
- the hard material particles are formed by abrasive powder, which are pressed or introduced by forging, rolling or pouring into the tread surface. A corrosion protection layer is not given here.
- the invention has the object of developing a sliding and / or mating ring of a drive seal to the effect that the corrosion behavior, in particular for use in abrasive and corrosive media, is improved without thereby the sliding and wear behavior are adversely affected.
- a sliding and / or mating ring of a drive seal comprising an angular cross-section body, with a Axiabchenkel, which serves to receive a spring element and a Radial leg, which is provided with a tread extending over a predetermined height, wherein at least the tread is provided with a corrosion protection layer which simultaneously forms the sliding layer.
- the corrosion protection layer is advantageously applied by electrochemical means, in particular by electroplating, on the running surface, or on further surface areas.
- the anticorrosion layer is formed by a chromium or chromium ceramic layer.
- solid lubricant particles can moreover be incorporated into the cracks as solid particles.
- graphite, hexagonal boron nitride and / or PTFE can be used here.
- the thickness of the anticorrosive layer, in particular on the tread, should be in the range between 0.01 and 1.0 mm.
- the grain size of the stored solid particles is chosen between 0.0005 and 0.015 mm.
- the sliding and / or counter ring is advantageously made of a cast material, wherein the corrosion protection layer / sliding layer on the one hand by a higher hardness compared to the base material (casting material) and on the other hand by a high corrosion resistance, especially when used in abrasive and corrosive media, such as seawater , distinguished.
- a higher hardness compared to the base material (casting material) and on the other hand by a high corrosion resistance, especially when used in abrasive and corrosive media, such as seawater , distinguished.
- the subject invention is illustrated by a Ausf ⁇ ihrungsbeispiels in the drawing.
- the single FIGURE shows an angular cross-sectional sliding and / or counter ring 1 of a drive seal not shown.
- the main body 1 'of the sliding and / or counter ring 1 has an axial leg 2 and a radial leg 3.
- a receiving area 4 is provided for a spring element not further shown, while in the region of the radial leg 3 a running surface 5 is provided, which has a certain radial height h.
- This tread 5 forms the so-called sliding surface.
- the main body 1 ' should consist of a cast material in this example.
- the tread / sliding surface 5 with a Corrosion protection layer 6 is coated.
- the anticorrosion layer 6 is to be formed in this example by a hard chrome layer which has been applied by electroplating on the running surface / sliding surface 5.
- the corrosion protection layer applied on the running surface 6 and, if required, on further surface areas may have a layer thickness of between 5 and 200 ⁇ m.
- the galvanic hard chrome layer can be equipped with a crack network extending through the entire layer thickness during its production, in which a wide variety of solid particles can be incorporated.
- Hard material particles such as diamond particles, tungsten carbide, chromium carbide or the like, are suitable here.
- solid particles in the form of solid lubricant particles can also be incorporated into the crack network to increase the sliding properties.
- Graphite, hexagonal boron nitride and / or PTFE are suitable here.
