Passivation (chemistry) - Wikipedia

Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air.

Most copper alloys, even in thick sections, do not require pre-heating because the thermal diffusivity is much lower than for copper. To select the correct preheat for a given application, consideration must be given to the welding process, the alloy being welded, the base metal thickness and to some extent the overall mass of the weldment.

smelting | Definition & Facts | Britannica

The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver. To achieve the high temperatures required for smelting, furnaces with forced-air draft were developed; for iron, temperatures even higher were required. Smelting thus represented a major technological achievement.
