Definitions
- the invention relates to a method for metallic coating, wherein a coating lance with an anode and a cathode is axially inserted into the bore and rotated about its longitudinal axis, an arc is generated between the anode and the cathode, into which a plasma gas mixture is introduced and ionized , wherein a plasma flow is generated, a coating powder is fed into the plasma flow and the plasma flow with the particles is sprayed onto the bore wall and a coating is formed on the bore wall, according to the preamble of claim 1.
- the invention also relates to a system for the metallic coating of a bore wall of a bore of a coating lance with an anode and a cathode, the coating lance being axially retractable into the bore and thereby rotatable about its longitudinal axis, a power source through which between the anode and the cathode Arc can be generated, in which a plasma gas mixture can be introduced via an introduction device, which is ionized in the arc to generate a plasma flow, a feed device for feeding a coating powder into the plasma flow and an injection nozzle which is aligned with the bore wall, with the plasma flow causing a coating is formed on the bore wall, according to the preamble of claim 13.
- a bore wall with a special coating.
- Various methods are known for such a coating, such as so-called flame spraying, laser spraying, plasma powder build-up welding or arc spraying with a melting wire electrode.
- flame spraying laser spraying
- plasma powder build-up welding or arc spraying with a melting wire electrode.
- a particularly efficient application of a coating is what is known as atmospheric plasma spraying.
- a plasma stream with a high temperature of up to 2000 K or more is generated in a burner lance by means of an arc and the introduction of a conveying gas. Fine coating particles can be introduced into this hot plasma flow, which particles melt in the plasma flow and are applied to the bore wall with the plasma flow at high speed.
- the invention is based on the task of specifying a method and a system with which a metallic coating can be efficiently applied to a bore wall.
- the object is achieved according to the invention on the one hand by a method with the features of claim 1 and on the other hand by a system with the features of claim 13.
- Preferred embodiments of the invention are given in the dependent claims.
- the method according to the invention is characterized in that the coating lance with an axial feed speed in the bore is retracted and rotated at a rotational speed of 420 rpm to 520 rpm and with a volume flow of conveying gas of 30 l / min to 70 l / min coating powder is injected at a feed rate of 90 g / min to 130 g / min will.
- the degree between melting and rapid cooling is particularly advantageous, so that a desired microporous layer structure results. This is supported by setting the delivery gas in a range from 30 l / min to 70 l / min.
- a preferred embodiment of the method consists in setting an axial feed rate of 3.8 mm / rev to 4.5 mm / rev, in particular from 4.1 mm / rev to 4.2 mm / rev. This results in a particularly stable layer structure with the desired structure. It is particularly preferred if the axial feed rate is 4.13 mm / rev.
- particularly good heating of the plasma current is brought about by setting a discharge current of 300 A to 400 A, in particular 360 A, between the anode and the cathode.
- a good surface application on the bore wall is also achieved in that the plasma flow with the particles is sprayed with an injection nozzle which has a diameter of 1 mm to 2 mm, preferably 1.5 mm.
- the lance is located in the middle of the hole, which preferably has a diameter of 7 cm to 15 cm.
- a flat nozzle with the same or a similar opening area can also be used, which for example can have a size of 1 mm by 3 mm.
- the injection nozzle is inclined upwards by 5 ° to 20 °, in particular between 8 ° to 12 °, particularly preferably 10 °, relative to the longitudinal axis. In this way, a largely radially directed material application can be achieved, since a deviation due to the axial advance can be compensated for by the inclination.
- the coating can be carried out in a single axial application.
- a particularly stable structure of the coating can be achieved according to a method variant according to the invention in that the coating is built up by several coating layers, in particular three to six coating layers, with one coating layer being formed by an axial overflow of the coating lance. It is particularly advantageous if there are four axial overflows with the coating lance over the bore wall.
- a particularly stable coating results in particular from the fact that a layer thickness of 150 ⁇ m to 300 ⁇ m, in particular 250 ⁇ m, is formed. With four overflows, a layer thickness between 60 ⁇ m and 70 ⁇ m can be applied.
- the plasma gas mixture can in principle be designed in any suitable manner. According to a further development of the invention, it is particularly advantageous that the plasma gas mixture is formed using argon, hydrogen, nitrogen and / or helium. These elements lead to a particularly effective plasma flow for the coating process.
- the coating powder can be supplied by a carrier gas.
- a rotational speed of the coating lance it is particularly advantageous that a rotational speed of 450 rpm to 465 rpm, in particular 459 rpm, is set. According to one finding of the invention, a particularly good and stable application of material results in this speed range.
- a preferred setting range is that a volume flow of the plasma gas mixture of 40 l / min to 50 l / min, preferably 44 l / min, is set. In this way, a good conveying effect for the coating powder can be achieved, with a necessary but not excessive cooling of the plasma flow resulting at the same time.
- Argon at 40 l / min and hydrogen at 4 l / min can preferably be used to form the plasma gas mixture.
- the feed rate of the coating powder is set to 110 g / min.
- commercially available coating powder for plasma spraying can be used for the coating.
- a coating powder with iron particles and / or other metals is used, the average size of the particles being between 100 nanometers and 100 ⁇ m. It is particularly preferred that these particles melt completely or not completely in the heated plasma stream, that is to say only on their upper side, and thus have a drop shape when they strike the coating wall.
- a coating can be composed of approximately spherical elements which, through targeted cooling, form a coating structure with micro-free spaces in between. In particular, there is no continuous solid connection, but rather the melted and cooling coating particles are only partially connected to one another, with preferably between 2% to 20% of the coating volume being formed by pore cavities.
- the system according to the invention is characterized in that a control is provided and designed so that the coating lance can be retracted into the bore at a uniform axial feed rate and rotated at a rotational speed of 420 rpm to 520 rpm and a volume flow of conveying gas of 30 l / min to 70 l / min and a feed rate of coating powder in a plasma flow of 90 g / min to 130 g / min.
