Bronze disease is an irreversible and nearly inexorable corrosion process that occurs when chlorides come into contact with bronze or other copper-bearing alloys. [1] It can occur as both a dark green coating, or as a much lighter whitish fuzzy or furry green coating. [ 1 ]
Protective elements for bronze fountains are particularly important, since water is one of the leading causes for alterations or corrosion in a bronze. [2] Bronze sculptures incorporated in fountains will need more layers of wax, because the spray of water will cause deterioration of the wax at a faster pace than would normally happen.
The process of pit nucleation is initiated by the depassivation of the protective oxide layer isolating the metal substrate from the aggressive solution. The depassivation of the protective oxide layer is the less properly understood step in pitting corrosion and its very local and random appearance probably its most enigmatic characteristic.
Patina (/ p ə ˈ t iː n ə / pə-TEE-nə or / ˈ p æ t ɪ n ə / PAT-ih-nə) is a thin layer that variously forms on the surface of copper, brass, bronze, and similar metals and metal alloys (tarnish produced by oxidation or other chemical processes), or certain stones [1] and wooden furniture (sheen produced by age, wear, and polishing), or ...
It's a mildly abrasive cleaner, so it's ideal for tackling those hard-to-tackle stains on tough materials like saucepans, cook tops, sinks, uPVC, barbecues, ceramic tiles, glass, garden furniture ...
Protective coatings can be good options for iron and steel objects. They help retain original appearance and protect against foreign bodies such as moisture and debris that can cause rust or corrosion. Clear coatings – Permalac [9] – Ormocer [10] – Paraloid B-72 [11]
