metrilised

Metrilised is a less common variant spelling that is sometimes used to refer to the process of applying a metallic coating to a surface, or to the coated surface itself. In standard terminology, this is known as metallisation (British English) or metallization (American English). The term “metrilised” may appear in regional texts or as an informal adaptation of metallisation.

The process involves depositing a thin layer of metal onto a substrate to improve properties such as electrical conductivity, reflectivity, corrosion resistance, or decorative appearance. Coatings can be continuous or patterned and thickness ranges from a few nanometers to micrometers, depending on the application and method used.

Common methods for metallisation include electroplating, electroless plating, sputtering (a form of physical vapor deposition), chemical vapor deposition, thermal evaporation, and thermal spraying. Substrates used in metallisation span metals, polymers, ceramics, and glass, with adhesion and compatibility between the substrate and metal being important design considerations.

Applications are broad, including electronic connectors and circuits, reflective optics, solar cells, packaging foils, automotive components, corrosion protection, and decorative finishes. Advantages of metallisation include enhanced electrical and thermal conductivity, increased surface hardness or reflectivity, and added barrier properties. Limitations encompass adhesion challenges, diffusion and intermetallic formation at higher temperatures, coating uniformity, cost, and environmental or safety concerns associated with certain plating baths and deposition processes.
