Definitions
- the invention relates to a cylindrical tread, for example a cylinder liner or a cylinder bore, made of a light metal alloy with a defined claw structure a not yet coated cylindrical tread, on which a wear layer can be applied firmly.
- Such a cylindrical tread is, for example, from the article by Hans Rininger "Flame-sprayed plain bearings" from “Der Machinen here” (1954, No. 7, page 6) known. there sawtooth recesses or threads with longitudinal grooves are made in the cylindrical running surface, to ensure a twist-proof adhesion.
- sawtooth recesses or threads with longitudinal grooves are made in the cylindrical running surface, to ensure a twist-proof adhesion.
- the wear resistance of cylindrical treads such as the Crankcase of an internal combustion engine, at least partially to increase that on the light metal alloy, for example, a wear layer made of an Fe-based alloy with additives such as C, Mn, Mo, V etc., an Al-based alloy with additives such as. Si, Fe, Cu, Ni etc. or a copper / nickel alloy is applied.
- the wear layer is preferably by welding, plasma spraying, flame spraying or high-speed jet spraying.
- the Coating light metal alloy roughened by a blasting process. That kind of However, pretreatment is very complex due to the blasting systems to be used creates only an undefined surface structure, the uneven voltage introduction caused in the wear layer, which means that not in all stress cases Adequate adhesion of the wear layer is guaranteed.
- the present invention is therefore based on the object of a remedy for the above to create problems described.
- This claw structure initially leads to a defined increase in the adhesive area of the coating tread. It also occurs in the subsequent coating process in the peaks to a higher energy load, which is partially a reproducible Diffusion compensation of the wear layer with the base material leads. It also matters the tips of the claw structure to melt, which the adhesion of the wear layer improve even further.
- the distance is too coated surface, especially with diameters of 60-120 mm, so small that in the coating medium no maximum acceleration can be achieved due to the low kinetic energy, the adhesion is reduced.
- the angle of impact of the media jet significantly less than 90 °, this results in poor adhesion of the coating medium in this zone.
- the macroscopic surface structure specifically produced in this way can be in the form of preferably grooves extending in the circumferential direction or also of spiral thread-like Profiles be formed. Furthermore, the adhesion can be radial and / or axial Direction can be improved by undercuts.
- the inner contour of the bore provided with claw structures has proven to be advantageous by welding, plasma spraying, flame spraying or high-speed jet spraying manufacture.
- the Energy (pinch effect) per unit area increased significantly, leading to an improvement in Shift liability leads.
- Figure 1 shows a longitudinal section through a cylindrical designed according to the invention Tread.
- the cylindrical tread 1 consists of a known aluminum alloy.
- a claw structure 2 in a known manner, in the present exemplary embodiment turned a thread profile.
- Claw structures 2 also in various other ways, such as pressure rolling, cutting, Milling etc. can be introduced into the cylindrical tread 1.
- slight undercuts 4 are attached to the claw structures 2.
- FIG. 2 A schematic representation of the machining process for applying one of the wear layer 3 through the media jet 5 shows FIG. 2.
- the claw structure 2 ensures this that the angle of incidence of the media beam 5 is almost 90 °.
- 3 shows this a first embodiment of the claw structure 2, which ensures this defined impact angle.
- the orientation of the partial flanks 6 is over the entire cylindrical running surface 1 constant, which leads to the fact that during the coating process the media jet 5 moved translationally along the longitudinal axis of the cylindrical tread 1 (see dash-dotted lines).
- Figure 4 shows a claw structure 2, the partial flanks 6 in the longitudinal direction of the cylindrical Tread 1 have a continuously decreasing angle of attack a.
- a claw structure 2 can be produced in a known manner, for example by a CNC machine become.
- the media jet 5 then only needs a rotary movement to carry out, which in turn leads to a simplification of the machining process.
