Description

Composición de recubrimiento de cromado.Chrome coating composition.

La presente invención se refiere a una composición de recubrimiento de cromado, en especial aplicable al campo de la hidráulica.The present invention relates to a chrome plating composition, especially applicable to field of hydraulics.

Más particularmente, la presente invención es aplicable a vástagos de cilíndricos hidráulicos o cualquier otra superficie metálica que esté en contacto con aceite u otro tipo de fluido hidráulico y que esté sometida a fricción durante el funcionamiento de la máquina donde se utilice, como por ejemplo, maquinaria móvil agrícola o de obras
públicas.
More particularly, the present invention is applicable to hydraulic cylindrical stems or any other metal surface that is in contact with oil or other type of hydraulic fluid and that is subjected to friction during operation of the machine where it is used, for example, agricultural or construction mobile machinery
public.

Antecedentes de la invenciónBackground of the invention

En el campo de la hidráulica, y en particular los vástagos de cilíndricos hidráulicos utilizados en maquinaría móvil agrícola, de obras públicas o similar, presentan el problema de que sufren un desgaste al estar sometidos a fricción durante el funcionamiento de la máquina donde se utilice, y presentan problemas de corrosión al estar sometidos al ambiente exterior.In the field of hydraulics, and in particular the hydraulic cylindrical stems used in machinery Agricultural mobile, public works or similar, present the problem that they suffer wear when subjected to friction during operation of the machine where it is used, and present corrosion problems when subjected to the outside environment.

Para solventar estos problemas, actualmente es conocida la aplicación de un recubrimiento de cromado formado por una o varias capas de cromo dispuestas sobre el substrato base de metal o acero del propio vástago. De esta manera, se evita que el acero o hierro recubierto por la capa de cromo, se oxide o se dañe al estar en contacto con el ambiente exterior, y permite que el vástago se deslice fácilmente al tener una superficie fina que evita una fricción que pueda crear un desgaste excesivo.To solve these problems, it is currently known the application of a chrome plating formed by one or several layers of chromium arranged on the base substrate of metal or steel of the stem itself. In this way, it prevents the steel or iron coated by the chrome layer, rust or damage by being in contact with the outside environment, and allowing the stem slides easily by having a thin surface that avoid friction that can create excessive wear.

Este tipo de recubrimiento tiene el inconveniente de que presenta una resistencia a la corrosión en el tiempo relativamente baja.This type of coating has the drawback that it has a corrosion resistance in the relatively low time.

Descripción de la invenciónDescription of the invention

El objetivo de la composición de recubrimiento de cromado de la presente invención es solventar el inconveniente que presentan los recubrimientos de cromado conocidos en la técnica, proporcionando una mayor resistencia a la corrosión en el tiempo.The purpose of the coating composition Chromium plating of the present invention is to solve the drawback which present the chromate coatings known in the technique, providing greater corrosion resistance in the weather.

La composición de recubrimiento de cromado, objeto de la presente invención, es aplicable a un substrato base de metal o acero que puede estar en contacto con aceite u otro tipo de fluido hidráulico y que en uso está sometido a fricción, y se caracteriza por el hecho de que comprende:The chrome plating composition, object of the present invention, is applicable to a base substrate of metal or steel that may be in contact with oil or other type of hydraulic fluid and that in use is subjected to friction, and characterized by the fact that it comprises:

a) to)
una capa de cromo depositada encima del substrato de metal o acero, teniendo dicha capa de cromo un espesor comprendido entre 5 y 50 micrómetros, ya layer of chromium deposited on top of the substrate of metal or steel, said chrome layer having a thickness between 5 and 50 micrometers, and

b) b)
al menos una capa de óxido de cromo depositada encima de la capa de cromo, teniendo dicha al menos una capa de óxido de cromo un espesor igual o superior a 20 manómetros.at least one layer of deposited chromium oxide above the chrome layer, said at least one layer having chrome oxide a thickness equal to or greater than 20 pressure gauges.

De este modo, se consigue una composición de recubrimiento de cromado compatible con el medio ambiente y con una resistencia a la corrosión y al desgaste mucho mayor que la obtenida en el estado de la técnica, mejorando así la vida útil del componente metálico. Dicho componente metálico puede ser, por ejemplo, un vástago de cilíndrico hidráulico o cualquier otra superficie metálica que esté en contacto con aceite y que esté sometida a fricción durante el funcionamiento de la máquina donde se utilice.In this way, a composition of chrome plating compatible with the environment and with a corrosion and wear resistance much greater than obtained in the state of the art, thus improving the service life of the metal component Said metallic component may be, by example, a hydraulic cylindrical rod or any other metal surface that is in contact with oil and that is subjected to friction during machine operation where be used

De acuerdo con una realización de la invención, la composición de recubrimiento de cromado además comprende una capa de origen polimérico tipo resina epoxídica o fenólica, depositada encima de la al menos una capa de óxido de cromo.According to an embodiment of the invention, The chrome plating composition further comprises a layer of polymeric origin type epoxy or phenolic resin, deposited on top of the at least one layer of chromium oxide.

De esta manera se mejora aún la resistencia a la corrosión y al desgaste del componente metálico.In this way the resistance to  corrosion and wear of the metal component.
