Many applications of ceramics and glasses require them to be joined to each other or to other materials such as metals. This article focuses on ceramic joining technologies, including glass-metal sealing, glass-ceramic/metal joining, ceramic-metal joining, ceramic-ceramic joining, and the more advanced joining of nonoxide ceramics. It also discusses metallizing, brazing, diffusion bonding, and chemical bonding.

The process of coating plastics with metals for functional purposes is called metallizing of plastics. This article discusses the metallizing of plastics, provides information on its history, and gives a short note on applications and adhesion properties of metallic coatings. It also discusses the selection of plastics for plating. This article also describes metallizing techniques, including plating (electrolytic or electroplating), vacuum metallizing and thermal spraying, and environmental considerations. The article discusses the quality assurance procedures for metallized plastic parts which include tests that assess the quality of the finish, coating thickness, adhesion, and corrosion resistance, and gives a short note on service performance, which includes service condition classifications.

This article focuses on different thin-film deposition techniques used to make superconducting films and discusses the properties and advantages of high-critical-temperature and low-critical-temperature materials in a number of applications, including signal processing and analog electronic devices. The article gives a brief introduction on superconducting materials, substrates and buffer layers and discusses the major deposition techniques such as, electron-beam co-evaporation, sputtering from either a composite target or multiple sources and laser ablation. The article also describes the in-situ film growth techniques for producing atomic oxygen by radio frequency excitation or microwave discharge or with ozone.
