Definitions
- the invention relates to a coating system for coating components with a particularly for fasteners for wheels and rollers. 5
- PTFE or graphite-containing coating systems are used. It is also known to use MoS2-based systems.
- a relationship between the tightening torque and the preload force that is to be set within predetermined limits is desired.
- the pretensioning force is within a certain range of variation with a fixed tightening torque of the 30 connecting elements. This range of variation is exacerbated by the use of different materials (light metal alloys, preferably aluminum or magnesium alloys or steel). The mechanical stress caused by multiple assembly and the physical impact and temperature effects that occur in practice are also problematic.
- the invention is therefore based on the problem of creating a coating system for coating components with dry lubricants which has considerably improved adhesion properties, increased corrosion resistance and, moreover, high chemical resistance.
- the problem is solved by a coating system in which the dry lubricant is applied to a zinc / nickel layer that has previously been treated with an oxidizing agent.
- the dry lubricant can also be applied to a conversion layer, which then lies between the oxidatively treated zinc / nickel layer and the dry lubricant.
- Organic or inorganic coating agents such as e.g. Silicates or polymer waxes.
- the Aquares product is particularly suitable.
- a particular advantage of the invention is that the combination of an oxidatively treated zinc / nickel layer with a dry lubricant has a high durability against physical and chemical influences and still has good flow properties. Even with multiple disassembly and reassembly - even in of the order of 20 repetitions - the ratio of tightening torque and pretensioning force in the case of connecting elements which are coated according to the invention remains unchanged. The preload achieved remains within narrow limits even when using different materials with a specified tightening torque. In particular, the adhesion and abrasion resistance of the system according to the invention and the impact resistance have been considerably improved compared to the prior art.
- the anti-friction coating Molykote D708 from Molykote is preferably used as the dry lubricant. A temperature resistance of -180 to 200 ° C is achieved with this system.
- a particular advantage of using oxidatively treated zinc nickel black with the coating system according to the invention is that the black materials required in conventional systems Coloring is eliminated, which makes it easier to visually inspect the coating system and reduces the number of top coats.
- the coloring of the coated object with the aid of the coating system according to the invention is retained even after prolonged intensive use and shows hardly any visible changes, which is particularly important in the case of a black coating system.
- the dry lubricant is preferably separated using the immersion centrifuge method and then burned in.
- Colloidal soot binding prevents contact corrosion.
