Para la obtención de la capa anticorrosiva (esmalte sol-gel) son especialmente apropiados sistemas sol-gel, que se distinguen por al menos uno de los siguientes parámetros y/o una de las siguientes substancias: un ácido silícico acuoso coloidal, que conduce a la formación de un esmalte sol-gel constituido por polisiloxanos reticulados en combinación conveniente con una disolución de silano alcohólica, en especial de una disolución de alcoxisilano mediante hidrólisis, condensación y secado. In order to obtain the anticorrosive layer (sol-gel enamel), sol-gel systems are particularly suitable, which are distinguished by at least one of the following parameters and / or one of the following substances: a colloidal aqueous silicic acid, which leads to the formation of a sol-gel enamel consisting of cross-linked polysiloxanes in convenient combination with an alcoholic silane solution, especially an alkoxysilane solution by hydrolysis, condensation and drying.
Son especialmente preferentes sistemas sol-gel que se encuentran disponibles, a modo de ejemplo, bajo el nombre comercial CERAPAINT de la firma Akzo Nobel. Los sistemas sol-gel citados anteriormente, y las capas anticorrosivas producidas a partir de los mismos, se distinguen por una composición química que posibilita un reciclaje mediante tecnología de fusión inmediato de las piezas de forja revestidas, sin que sea necesario desgastar química o mecánicamente la capa anticorrosiva. Por lo tanto, se pueden evitar medidas de técnica medioambiental adicionales antes del reciclaje. Todos los tipos sol-gel citados anteriormente son inocuos, inodoros, y no son corrosivos, y por consiguiente son elaborables sin medidas de seguridad y protección elevadas. Especially preferred are sol-gel systems that are available, by way of example, under the trade name CERAPAINT of Akzo Nobel. The sol-gel systems mentioned above, and the anticorrosive layers produced therefrom, are distinguished by a chemical composition that enables recycling by means of immediate fusion technology of the coated forging parts, without the need to chemically or mechanically wear out the anticorrosive coating Therefore, additional environmental technical measures can be avoided before recycling. All the sol-gel types mentioned above are harmless, odorless, and non-corrosive, and therefore are workable without high safety and security measures.
Es muy especialmente preferente, como se indica ya inicialmente, que la capa anticorrosiva presente un grosor extremadamente reducido. El grosor asciende preferentemente a menos de 10 m, de modo especialmente preferente menos de 5 m, en especial 2 m a 4 m. Preferentemente no se sobrepasa un grosor mínimo de 0,5 m. Además de otras ventajas, una extensión de grosor reducida de la capa anticorrosiva conduce a un aumento de peso minimizado. Por consiguiente se ofrece un potencial de construcción ligera elevado frente a sistemas de revestimiento convencionales. It is very particularly preferred, as already indicated initially, that the anticorrosive layer has an extremely reduced thickness. The thickness is preferably less than 10 m, especially preferably less than 5 m, especially 2 m to 4 m. Preferably, a minimum thickness of 0.5 m is not exceeded. In addition to other advantages, a reduced thickness extension of the anticorrosive layer leads to a minimized weight gain. Therefore a high light construction potential is offered compared to conventional coating systems.
En el perfeccionamiento de la invención se considera una ventaja que, en el caso de la pieza moldeada y/o estructural, se trate de un componente de camión, de modo muy especialmente preferente de un componente de camión relevante para la seguridad, es decir, portador y/o para la absorción de carga, en especial de un parachoques, un protector antichoques lateral, o de un componente del mecanismo de traslación del camión, a modo de ejemplo un brazo oscilante longitudinal, un brazo oscilante oblicuo, un brazo oscilante portador o un brazo oscilante transversal. También es posible configurar la pieza de forja como componente de una suspensión de rueda In the improvement of the invention, it is considered an advantage that, in the case of the molded and / or structural part, it is a truck component, very particularly preferably a truck component relevant for safety, that is, carrier and / or for load absorption, especially of a bumper, a side crash guard, or of a component of the truck translation mechanism, for example, a longitudinal oscillating arm, an oblique oscillating arm, a carrier oscillating arm or a transverse swing arm. It is also possible to configure the forge as a component of a wheel suspension
o motor de un automóvil. Otras aplicaciones son concebibles igualmente. De este modo, la pieza moldeada y/o estructural se puede configurar, a modo de ejemplo, como eslabón de unión, convenientemente como bisagra o herraje. Alternativamente es realizable una configuración como componente hidráulico, o bien como fijación de armadura o asiento. Del mismo modo, la pieza moldeada y/o estructural se puede configurar como componente de automóvil decorativo, en especial para el espacio interno del automóvil. También es posible la realización de la pieza moldeada y/o estructural como componente exterior del automóvil, a modo de ejemplo como carcasa de espejo exterior, asidero de puerta o parapeto de techo. or car engine. Other applications are equally conceivable. In this way, the molded and / or structural part can be configured, as an example, as a connecting link, conveniently as a hinge or hardware. Alternatively, a configuration is possible as a hydraulic component, or as a frame or seat fixing. Similarly, the molded and / or structural part can be configured as a decorative automobile component, especially for the internal space of the automobile. It is also possible to make the molded and / or structural part as an exterior component of the car, for example as an exterior mirror housing, door handle or roof parapet.
Es especialmente conveniente configurar la pieza moldeada y/o estructural, en especial la pieza de forja, como pieza portadora de carga para aplicaciones en la industria automovilística. Además, una pieza de forja provista de una capa anticorrosiva, diseñada para la absorción de carga, es apropiada para aplicaciones costa afuera, en las que dominan condiciones medioambientales muy crudas. Las piezas de forja se pueden emplear también en aeronáutica, en industria electrónica o en la industria del transporte, en especial como piezas portadoras de carga. It is especially convenient to configure the molded and / or structural part, especially the forging part, as a load bearing part for applications in the automotive industry. In addition, a forge piece provided with an anticorrosive layer, designed for load absorption, is suitable for offshore applications, in which very harsh environmental conditions dominate. Forging parts can also be used in aeronautics, in the electronics industry or in the transport industry, especially as load bearing parts.
Como ya se ha indicado, la invención conduce también a un procedimiento para la producción de una pieza moldeada y/o estructural configurada como se describe anteriormente, en especial de una pieza de forja, que se distingue por una capa anticorrosiva (esmalte sol-gel), que procede de un sistema sol-gel. El núcleo del procedimiento es humectar, o bien revestir el componente de aluminio o de una aleación de aluminio, preferentemente forjado, en especial forjado en un troquel, con un sistema sol-gel, a partir del cual se produce entonces la capa anticorrosiva, en caso dado mediante un proceso de endurecimiento, o bien secado y/o tratamiento térmico, subordinado al proceso de revestimiento. As already indicated, the invention also leads to a process for the production of a molded and / or structural part configured as described above, especially a forging piece, which is distinguished by an anticorrosive layer (sol-gel enamel ), which comes from a sol-gel system. The core of the process is to wet, or to coat the aluminum component or an aluminum alloy, preferably forged, especially forged in a die, with a sol-gel system, from which the anticorrosive layer is then produced, in case given by a hardening process, or drying and / or heat treatment, subordinated to the coating process.
El procedimiento se puede integrar en linea o como etapa de proceso de desviación en una línea de producción existente con gasto reducido. The procedure can be integrated online or as a deviation process stage in an existing production line with reduced expense.
Según la invención, el sistema sol-gel para la formación de la capa anticorrosiva se debe endurecer mediante un tratamiento térmico, efectuándose el endurecimiento acelerado de manera combinatoria con el tratamiento térmico aplicado para piezas de forja en estado envejecido artificialmente. La temperatura elevada para el secado, o bien endurecimiento combinatorio del esmalte sol-gel, y el tratamiento térmico específico del material es mayor que 80ºC, preferentemente mayor que 115ºC, y en especial mayor que 140ºC. La temperatura elevada es menor que 210ºC. La temperatura elevada se sitúa entre 150ºC y 200ºC de modo especialmente preferente. According to the invention, the sol-gel system for the formation of the anticorrosive layer must be hardened by means of a heat treatment, the accelerated hardening being carried out in combination with the heat treatment applied to forged parts in an artificially aged state. The high temperature for drying, or combinatorial hardening of the sol-gel enamel, and the specific heat treatment of the material is greater than 80 ° C, preferably greater than 115 ° C, and especially greater than 140 ° C. The elevated temperature is less than 210 ° C. The elevated temperature is between 150 ° C and 200 ° C especially preferably.

La aplicación del esmalte sol-gel se efectúa ventajosamente antes o durante el envejecimiento artificial, de modo que se puede prescindir de un paso de endurecimiento separado. The application of the sol-gel enamel is advantageously carried out before or during artificial aging, so that a separate hardening step can be dispensed with.
Respecto a los métodos de revestimiento para la aplicación del sistema sol-gel sobre el componente de aluminio, o bien de aleación de aluminio, que puede presentar una superficie lisa, sometida a tratamiento con chorro de arena o estructurada, existen diversas posibilidades, a modo de ejemplo el esmaltado. En este caso son preferentes procedimientos de inyección, pulverización y/o inmersión, o bien de remojado por inmersión. Regarding the coating methods for the application of the sol-gel system on the aluminum component, or aluminum alloy, which can have a smooth surface, subjected to sandblasting or structured treatment, there are several possibilities, by way of as an example enamelling. In this case, injection, spraying and / or immersion procedures, or immersion soaking are preferred.
Es especialmente conveniente que el componente de aluminio o de una aleación de aluminio, convenientemente desengrasado o decapado, y seguidamente lavado, o bien depurado, se elabore de modo subsiguiente tras la aplicación y/o el endurecimiento del sistema sol-gel, a modo de ejemplo por medio de un procedimiento de separación con arranque de viruta, con cortes no determinados o determinados geométricamente, o un procedimiento de separación sin arranque de viruta, en el que no se produce ninguna substancia sin forma en el sentido de virutas (por ejemplo cortes de cizallamiento, cortes finos). También es posible una mecanización subsiguiente mediante procedimientos de desgaste térmicos, químicos y/o electroquímicos, a modo de ejemplo en el sentido de la norma DIN 8580. En especial la capa anticorrosiva producida a partir de un sistema sol-gel posibilita la mecanización tras la formación de la capa anticorrosiva, es decir, tras el endurecimiento del sistema sol-gel, ya que la capa anticorrosiva, debido a la disposición inmediatamente sobre el aluminio, o bien la aleación de aluminio, no tiende al resquebrajamiento en la mecanización, y en este aspecto las zonas mecanizadas no inmediatamente siguen protegidas óptimamente ante ataques corrosivos. It is especially convenient that the aluminum or an aluminum alloy component, conveniently degreased or pickled, and then washed, or scrubbed, be elaborated subsequently after application and / or hardening of the sol-gel system, by way of for example, by means of a chip removal procedure, with cuts not determined or determined geometrically, or a chip removal procedure, in which no formless substance is produced in the direction of chips (for example cuts of shear, fine cuts). Subsequent machining is also possible by thermal, chemical and / or electrochemical wear processes, by way of example in the sense of DIN 8580. Especially the anticorrosive layer produced from a sol-gel system enables machining after formation of the anticorrosive layer, that is, after the hardening of the sol-gel system, since the anticorrosive layer, due to the arrangement immediately on the aluminum, or the aluminum alloy, does not tend to break down in mechanization, and in This aspect does not immediately mechanized areas remain optimally protected against corrosive attacks.
La invención conduce también al empleo de un sistema sol-gel, en especial de esmalte sol-gel, a partir de un polisiloxano y ventajosamente un esmalte sol-gel constituido por un polisiloxano producido a partir de una disolución de silano alcohólica, en especial una disolución de alcoxisilano y una disolución de ácido silícico acuosa coloidal, para la formación de una capa anticorrosiva, preferentemente con una apariencia decorativa, sobre un componente forjado de aluminio o de una aleación de aluminio. The invention also leads to the use of a sol-gel system, especially sol-gel enamel, from a polysiloxane and advantageously a sol-gel enamel consisting of a polysiloxane produced from an alcoholic silane solution, especially a alkoxysilane solution and a colloidal aqueous silicic acid solution, for the formation of an anticorrosive layer, preferably with a decorative appearance, on a forged aluminum component or an aluminum alloy.
Un componente mecanizado de modo subsiguiente, o sometido a análisis destructivo, debido a la buena adherencia de capa y a la congruencia de las superficies de separación del revestimiento y del material básico, no presenta preferentemente una corrosión filiforme. A component machined in a subsequent way, or subjected to destructive analysis, due to the good adhesion of the layer and the congruence of the surfaces of separation of the coating and of the basic material, preferably does not present a filiform corrosion.
Además, un componente mecanizado de modo subsiguiente, o sometido a análisis destructivo, debido a la buena adherencia de capa y a la congruencia de las superficies de separación del revestimiento y del material básico, no presenta preferentemente un peligro de lesión (por ejemplo mediante partículas de cantos vivos o salientes de canto). In addition, a component machined in a subsequent manner, or subjected to destructive analysis, due to the good adhesion of the layer and the congruence of the surfaces of separation of the coating and the basic material, preferably does not present a danger of injury (for example by particles of live songs or outgoing songs).
De modo muy especialmente preferente, una pieza moldeada y/o estructural producida por medio del procedimiento según la invención se distingue por una composición química de la capa anticorrosiva que posibilita un reciclaje por tecnología de fusión inmediato de las piezas moldeadas, o bien estructurales revestidas, sin desgaste químico y/o mecánico previo de la capa anticorrosiva. Very particularly preferably, a molded and / or structural part produced by means of the process according to the invention is distinguished by a chemical composition of the anticorrosive layer that allows recycling by immediate fusion technology of the molded, or structurally coated, parts, no previous chemical and / or mechanical wear of the anticorrosive layer.
