Abstract
A method for treating a pipe, in particular a motor vehicle pipe, wherein a flare is generated at least at one pipe end of the pipe. At least areas of the flare are provided with at least one layer, which changes the friction properties of the coated surface of the flare. The flare is coated by means of plasma coating.
Claims15
A method for treating a pipe comprising the steps,
- generating a flare at least at one pipe end of the pipe, and
- plasma coating areas of the flare with at least one layer, which changes the friction properties of the coated surface of the flare;
- wherein a first layer with a friction value μ1 is applied at least in areas to the flare by means of plasma coating, and a second layer with a friction value μ2 is applied at least in areas to the flare by means of plasma coating, and that the second friction value μ2 is larger than the first friction value μ1.
