Abstract

SISTEMA, MéTODO E EQUIPAMENTO PARA ELETRODEPOSIçãO CONTìNUA DE PEçAS A TRABALHAR ALONGADAS Um sistema eletrodeposita as superfícies cilíndricas interna e externa de uma peça a trabalhar alongada, tal como um tubo ou eixo. A peça a trabalhar é continuamente eletrodepositada com soluções metálicas por meio de um ânodo móvel que galvaniza gradualmente o comprimento axial da peça a trabalhar em vez de galvanizar a peça inteira ou partes grandes da peça de uma vez.SYSTEM, METHOD AND EQUIPMENT FOR CONTINUOUS ELECTRODEPOSITION OF EXTENDED WORKING PARTS A system electroplates the inner and outer cylindrical surfaces of an elongated workpiece, such as a tube or shaft. The workpiece is continuously electroplated with metal solutions by means of a moving anode that gradually galvanizes the axial length of the workpiece instead of galvanizing the entire part or large parts of the part at one time.
