SURFACE TREATMENT OF COPPER MEMBER
PURPOSE: To suppress the rise of natural potential and to prevent pitting corrosion by forming an oxidized coating film on a copper member by oxidation under heating in an oxygen-contg. atmosphere. CONSTITUTION: A copper member such as a copper tube is heated in an oxygen- contg. atmosphere such as...

| description | PURPOSE: To suppress the rise of natural potential and to prevent pitting corrosion by forming an oxidized coating film on a copper member by oxidation under heating in an oxygen-contg. atmosphere. CONSTITUTION: A copper member such as a copper tube is heated in an oxygen- contg. atmosphere such as air to form a corrosion resistant oxidized coating film of about 10-500nm thickness on the surface of the copper member. Since this oxidized coating film formed by surface treatment acts as a barrier to electronic conduction, even when an active oxygen producing field is formed, a cathode reaction is not accelerated, the rise of natural potential does not occur and pitting corrosion is prevented. |
