Abstract

LA INVENCION SE REFIERE A UNA ALEACION DE COBRE RESISTENTE A LA CORROSION CONSISTIENDO EN COBRE Y POR LO MENOS DOS ELEMENTOS DE ALEACION QUE TIENEN UN POTENCIAL DE TENSION ELECTROQUIMICO PARECIDO AL DEL COBRE FORMAN UNA CAPA DE RECUBRIMIENTO LIBRE DE POROS Y MUY ADHERENTE DE OXIDOS, OXIHIDRATOS Y/O HIDROXIDOS. LA CANTIDAD DE ELEMENTOS INDIVIDUALES PERMANECE DENTRO DE LIMITES DENTRO DE LOS CUALES LA REACCION PERMANECE BAJO CONDICIONES TECNICAS DE REFRIGERACION EN LA ZONA DE MEZCLA CRISTALES. ESTA ALEACION DE COBRE SE CARACTERIZA A TRAVES DE LO SIGUIENTE; CONTIENE UN 99,0% EN PESO DE COBRE, EL PUNTO DE FUSION DE LA MEZCLA DE CRISTALES ES SUPERIOR A 450 C, DOS ELEMENTOS DE ALEACION DE VALENCIA DIFERENTE FORMAN EN LA CAPA DE RECUBRIMIENTO COMPUESTOS QUIMICOS ESTABLES TERMODINAMICAMENTE EN LA FORMA Y MODO MENCIONADO, YA QUE AMBOS ELEMENTOS DE ALEACION ADMITEN UNA VALENCIA MEDIA ENTRE 2,5 Y 3,0. LA DIFERENCIA DE VALENCIA ASCIENDE MAXIMAMENTE A 3.THE INVENTION IS REFERRED TO A CORROSION RESISTANT COPPER ALLOY CONSISTING OF COPPER AND AT LEAST TWO ELEMENTS OF ALLOY THAT HAVE A POTENTIAL OF ELECTROCHEMICAL VOLTAGE RELATED TO COPPER FORM A VERY STICKY, VERY ADHERENT OX OXIDIZING COAT AND / OR HYDROXIDES. THE QUANTITY OF INDIVIDUAL ELEMENTS REMAINS WITHIN LIMITS WITHIN WHICH THE REACTION REMAINS UNDER TECHNICAL CONDITIONS OF REFRIGERATION IN THE CRYSTAL MIXING AREA. THIS COPPER ALLOY IS CHARACTERIZED THROUGH THE FOLLOWING; CONTAINS 99.0% IN COPPER WEIGHT, THE MELTING POINT OF THE CRYSTAL MIXTURE IS GREATER THAN 450 C, TWO DIFFERENT ALLOY ELEMENTS FROM VALENCIA FORM THE STAINLESSLY CHEMICAL STABLE CHEMICAL COMPOUNDS, SINCE BOTH ALLOY ELEMENTS ALLOW AN AVERAGE VALENCE BETWEEN 2.5 AND 3.0. THE DIFFERENCE IN VALENCIA MAXIMUMLY INCREASES 3.
