Definitions
- the invention relates to plastic pump parts with a protective surface, especially pump rotors, joint parts or the like.
- Parts that are subjected to abrasive stress are conventionally made of metal made to ensure good wear resistance.
- Metal parts with a precisely machined surface are however, it is expensive to manufacture, since it usually involves a series of processing steps is required in order to be dimensioned precisely Finished part and to get a desired surface quality to achieve.
- Plastic parts can be with high accuracy and produce good surface quality inexpensively, for example by casting, pressing or others in this context known molding processes.
- a more wear-resistant around plastic parts It is known to give surface to the endangered Harden surfaces of a plastic part by some kind of varnish is applied to the plastic surface by heat treatment cures. With plastic glasses has this method has proven itself. For highly abrasive conditions, where e.g. the rotor is exposed to an eccentric screw pump, the hardening achieved with the aforementioned method is sufficient Plastic surface, however, by far not enough.
- JP 62-203988 A describes a rotor and a housing Pump, which consist of a fiber-reinforced plastic and with a layer of Ti deposited by ion plating or TiN are provided.
- DE 40 39 352 A1 describes a method and a device for the production of layers on plastic surfaces.
- a plastic surface first an adhesion-promoting primer, then an aluminum layer and finally a protective layer applied.
- the primer and the Protective layers consist of SiC or SiOC.
- the invention has for its object plastic pump parts to provide their wear resistance and / or corrosion resistance corresponds to that of metal parts.
- the top layer consists of a cobalt / Nickel / chrome / molybdenum mixture, made of tungsten carbide, chrome carbide, or an oxide ceramic material and is by means of high-speed flame spraying, Plasma or thermal spray powder spraying or applied by means of oxyacetylene flame spraying Service.
- the invention is based on the surprising finding underlying that by means of a metallic intermediate layer, the adheres well to the plastic core and is also excellent Primer for the actual wear and / or corrosion protection performing top layer forms, plastic pump parts can be produced, their wear resistance and / or corrosion resistance of those of metal parts not inferior.
- the wear and / or corrosion protection Top layer can be tailored to the desired To have surface properties. The above procedures have to apply the layers when coating of metal parts already proven and are experts on this Area known.
- the metallic connection layer consists of zinc with a purity of over 99%.
- the zinc preferably has one Purity of ⁇ 99.9%, especially a purity of 99.99%. ever the purer the zinc, the better the metallic connection layer adheres on the plastic core. Zinc with a purity of below 99% has proven unsuitable for the coating process exposed.
- the metallic connection layer made of an aluminum-silicon alloy.
- the aluminum-silicon alloy used preferably contains between 5 and 15 wt .-% silicon and as Rest aluminum.
- contamination by others Metals can be contained in usual amounts.
- it is not critical if up to 0.1% magnesium, 0.1% manganese, 0.5% Iron, 0.03% titanium, 0.03% copper, and / or 0.07% zinc in the Alloy are included.
- the relatively low melting point an aluminum-silicon alloy with the stated proportion Silicon is particularly beneficial since most plastics do not have a very high temperature resistance.
- Especially preferred aluminum-silicon alloys for the connection layer melt in a temperature range from 570 ° C to 615 ° C, especially in a temperature range from 570 ° C to 590 ° C.
- the material with material no. 3.2285 called.
- the layer thickness of the connecting layer is 25 ⁇ m to 150 ⁇ m and in particular 50 ⁇ m to 100 ⁇ m. If a certain Intended use or a certain material pairing require the layer thickness of the connection layer can be the specified But also fall below or exceed values.
- connection layer by means of arc spraying on the plastic core muster. With this type of application uniform connection layer thicknesses even on complicated molded plastic cores reach without the plastic material is too thermally stressed.
- the layers to be coated must be coated before the connection layer is applied Clean surfaces in the usual way, for example with industrial alcohol, or by targeted blasting activate.
- the cover layer consists of aluminum oxide or chromium oxide, can but also a composite layer made of different metal materials or be made of metal and oxide ceramic materials.
- the total layer thickness of the top layer is 50 ⁇ m to 400 ⁇ m, depending on the application of the coated plastic pump part and number of layers of material resulting in the top layer.
- the plastic core can in particular be made of polyether ether ketone (PEEK) or polyamide. Mixtures of these materials are suitable.
- the plastic pump parts according to the invention have comparable metal parts have a significantly lower weight and yet wear and / or corrosion resistance, which corresponds to those of the metal parts.
- the plastic pump parts according to the invention inexpensively manufacture, not least due to the weight-saving plastic core.
- the connection layer according to the invention enables only the application of wear and / or corrosion protection Top layer.
