BLACK PLATE Meaning and
Definition
-
Black plate refers to a type of steel sheet or plate that has a dark, iron oxide coating on its surface. This coating, also known as black oxide or blackening, is created through a chemical process called ‘pickling’. The plate is immersed in an acid solution, typically a mixture of sulfuric acid and chlorate, which removes any rust or impurities present on the surface of the steel. The result is a dark, matt black finish that provides protection against corrosion.
Black plate is often used in applications where long-term exposure to moisture or corrosive environments is a concern. The black oxide layer acts as a barrier, preventing further oxidation and protecting the underlying steel from rusting. This makes black plate particularly suitable for manufacturing automotive parts, electrical appliances, and other products that require durability and resistance to corrosion.
In addition to its protective properties, black plate can also be used for decorative purposes. The black oxide coating offers an attractive, distinctive finish that is sometimes desired for aesthetic reasons. However, it is important to note that the black oxide layer is relatively thin and can wear off over time, especially with heavy use or exposure to abrasive substances.
Overall, black plate is a type of steel plate that has undergone a pickling process to achieve a black oxide coating, providing both corrosion resistance and an appealing appearance.

Etymology of BLACK PLATE
The term "black plate" has its roots in the steel industry. In the late 19th and early 20th centuries, steel mills would produce sheets of steel with a dark, blackish oxide coating to protect them from rust. These sheets were commonly referred to as "black plates" due to their appearance. This term has been used specifically for flat plates of steel that have undergone this process. Over time, the term has also been applied to other products with a similar appearance, such as black ceramic plates or black coated materials.
