Bonderize is a brand name for a process of coating metal to prevent rust. However, the word 'bonderize' is often used to mean any process that applies a chemical coating to improve adhesion. Some synonyms for the word bonderize include phosphating, chromating, galvanizing, and anodizing. Each of these words refers to a particular process that applies a chemical coating to metal, thereby improving its durability and resistance to corrosion. Phosphating involves the use of phosphates to produce a layer of insoluble precipitate on the metal surface, while chromating involves the use of chromium to produce a protective layer. Galvanizing utilizes a layer of zinc; anodizing utilizes electrolytes to create an oxide layer on the surface of aluminum.
