Definitions
- the field of the present invention is that of the surface treatment of mechanical parts and, in particular, that of the compaction of anodic paints for the protection of turbine engine parts.
- Some aircraft engine parts have very high mechanical loads and only specific materials can meet the mechanical strength requirements imposed on them. These materials have, in general, the disadvantage of being very sensitive to corrosion; it is therefore imperative to protect them with a product that is likely to withstand the environment in which these parts evolve (high temperature, presence of engine oil, kerosene, etc. ).
- the corrosion protection currently used consists of a covering of the part with a paint resistant to the high temperatures and the various fluids mentioned above. But this painting being classified CMR (for Carcinogenic, Mutagenic, Reprotoxic), it is struck by the REACH regulation on the registration, the evaluation, the authorization and the restrictions of the chemical substances. It has therefore been necessary to look for a new method of protection to overcome the constraints related to this regulation.
- a first solution consisted in basing the protection system no longer on the sole principle of a covering by a paint but on a physicochemical process, called anodic painting.
- This process consists in projecting onto the surface of the part a liquid loaded with metal pigments, such as aluminum or zinc, and then heating the part in an oven to polymerize the projected product.
- metal pigments such as aluminum or zinc
- the protection ceases, the part becoming sensitive to electrochemical corrosion.
- it is advisable to make the surface layer conductive so as to make it a sacrificial layer which will corrode preferentially, in place of the metal of the part to be protected.
- the subject of the invention is a process for compacting sand-blasting anodic paints comprising sending at least two jets of an abrasive material towards a part covered by said paint, said jets being oriented from convergent manner and meeting at a point of focus, characterized in that said point of focus is positioned upstream of the piece.
- the arrangement of the jets of abrasive material has a symmetry with respect to the direction perpendicular to the surface to be treated.
- the jets of abrasive material are two in number and form an angle of 90 ° between them.
- the distance of the focusing point from the surface of the workpiece is between 200 and 300 mm.
- the sanding pressure is greater than 2 bars. It is therefore possible to use the existing sandblasting facilities, by simply making a drop in the sand spray nozzles.
- FIG. 1 is a schematic front view of a sanding device of a part, according to the prior art, according to one embodiment of the invention
- - Figure 2 is a schematic view, from above, of a sanding device of a part, according to the prior art
- FIG. 3 is a diagrammatic view, from the front, of a blasting device of a part, according to one embodiment of the invention.
- FIG. 4 is a schematic view, from above, of a sandblasting device of a part, according to one embodiment of the invention.
- FIG. 1 and 2 we see, respectively in front view and in top view, sanding a workpiece 1 as it is commonly practiced for the surface finish of a turbomachine part.
- the conventional sanding is carried out with two nozzles 2, which are oriented at 90 ° to each other and which each send a bundle of sand 3 perpendicular to the surface of the part 1, the two jets propagating in the same plan.
- the distance "d" from the straight line connecting the two nozzles 2 to the piece 1 is such that the two beams 3 meet at a focusing point 4 which is located on the piece 1, that is to say they reach both have the same point to sand.
- FIGS. 3 and 4 is seen, respectively in front view and in top view, the compaction, according to the invention, of the paint which covers the workpiece.
- the two nozzles 2 are positioned as before with jets 3 oriented in the same plane at 90 ° to each other and with the same solid angle of divergence.
- the sweeping along the piece is done, again, in the same way as for a conventional sandblasting.
- the distance at which the nozzles are placed from the surface of the part is increased compared to the previous case, so that the straight line connecting them is now at a distance greater than the focusing distance d.
- the adjustment of the nozzle / workpiece distance is made so that the focal point 4 of the jet is on the surface of the workpiece 1, that is to say where the kinetic energy of sand is the strongest.
- the sanding pressures used are commonly of the order of 3 bars.
- the focusing length d is invariable, irrespective of the sand blasting pressures implemented.
- the invention consists in increasing the nozzle / piece distance without changing the angle of incidence of 90 ° of the sand bundles between them.
- the focal point 4 of these beams is then no longer at the level of the room itself, but at a point of convergence where the sand jets intertwine.
- the collision of the particles then generates a beam diffraction, which has the effect of reducing the speed of the sand particles on the part 1 thus reducing its kinetic energy and making the diffracted beam 5 lose its power.
- the consequence is a conservation of the cosmetic integrity of the paint while making it electrically conductive.
- this solution has the advantage, because of the greater divergence of the diffracted beam 5, to cover a larger surface area of the workpiece and thus to be able to increase the scanning speed and thus reduce the treatment cycle. .
- the invention recommends for this purpose a distance of recoil "r" of the piece relative to the focal point, which is of the order of 250mm, and in any case between 200 and 300 mm.
