Corrosion in The Electrical or Electronic Components of Telecommunications Equipment

corrosion of chromate conversion coatings on aluminum alloys in electrical and electronic equipment

chromate conversion coating is applied on aluminum 6061. the optimum conditions for chromate bath composition and immersion time are also obtained for standard requirements provision such as corrosion resistance in salt spray test, electrical resistance and coating quality. the applied coatings are electrochemically tested in sea and distilled water. according to tafel and cyclic polarization c...

Electrical Equipment and Components in Adverse/Corrosive Environments

Background The installation of electrical equipment in adverse environments containing corrosive gases, liquids, or dust can cause severe and rapid deterioration of the equipment. Historically, it has been recommended to customers to keep electrical equipment free of these contaminants through the use of special enclosures or separate rooms. Furthermore, the NEC (National Electrical Code) does ...

Reliability Assessment of Telecommunications Equipment

This thesis studies the reliability of telecommunications equipment, its components, and the systems made using those components. Special attention is paid to creating stronger links between the reliability analyses performed at different hierarchy levels. The thesis starts with a temperature derating study. It is found out that the generic handbook based procedures may not always be very attra...

New characterisation method of electrical and electronic equipment wastes (WEEE).

Innovative separation and beneficiation techniques of various materials encountered in electrical and electronic equipment wastes (WEEE) is a major improvement for its recycling. Mechanical separation-oriented characterisation of WEEE was conducted in an attempt to evaluate the amenability of mechanical separation processes. Properties such as liberation degree of fractions (plastics, metals fe...
