What does platinize mean?
Platinize is a technical verb meaning to coat a surface with platinum. The process may be used to create a protective layer, improve electrical conductivity, provide chemical resistance, or give a component a platinum finish. It is especially associated with electroplating, laboratory electrodes, high-temperature equipment, and other applications where the exceptional stability of platinum is valuable. In general use, the word is uncommon, and a writer may choose to say plate a surface with platinum when the technical distinction is not important. The related term platinization names the coating process or its result, while platinized describes an object that has received such a coating. The word derives from platinum, the chemical element, combined with the suffix -ize, meaning to make or treat in a particular way.

Where does platinize come from?
Platinize is formed in English from platinum plus the productive suffix -ize. Its meaning follows the ordinary English pattern of naming a coating process after the metal used for the coating. Platinum itself takes its name through an earlier historical form, platina, from a Spanish word for a small silver-colored platinum nugget. The derivative is chiefly preserved in specialist scientific and technical vocabulary.
