Galvanic gold-plating process for turbine blades, ships' masts, drive shafts aircraft wing structures, load-bearing components in buildings and bridges

摘要

In a process to enhance the long-term durability of high alloy steel an ultra-thin coating of gold, copper or palladium is applied to the surface by a galvanic process e.g. cathode atomisation. When the alloy is used in a warm-moist environment, the thin layer on the alloy crystal surface prevents the formation of an electrical potential and suppresses the formation of micro-fissures between crystals.
