Fretting Corrosion in Electric Contacts
Fretting corrosion is a form of accelerated atmospheric oxidation which occurs at the interface of contacting materials undergoing slight, cyclic relative motion. In electric contacts involving non-noble metals, fretting action can cause rapid increases in contact resistance, proceeding to virtual open circuits in a matter of minutes in the worst cases. Experimental results of resistance increa...
متن کاملFretting corrosion of tin-plated contacts
The susceptibility of tin-plated contacts to fretting corrosion is a major limitation for its use in electrical connectors. The present paper evaluates the influence of a variety of factors, such as, fretting amplitude (track length), frequency, temperature, humidity, normal load and current load on the fretting corrosion behaviour of tin-plated contacts. This paper also addresses the developme...
متن کاملFretting corrosion of tin-plated contacts: Evaluation of surface characteristics
The surface characteristics of the contact zone of tin-plated copper alloy contacts subjected to fretting motion for 8000, 16,800 and 48,000 cycles under unlubricated conditions are presented. The nature of the contact zone, at the verge of wearing out of the tin coating as well as upon the coating is completely worn out, is assessed using scanning electron microscopy (SEM), energy-dispersive X...
متن کاملCharacterizing fretting particles by analysis of SEM images.
Detailed surface characteristics of the particles produced during fretting may well be significant in determining their biological effects. Apart from a broad size determination very few attempts have been made at devising means of describing profile textures of particles. An approach is presented for describing the nature of particle shape and surface texture, as detected on the particle profi...
متن کاملCharacterizing Tools for Visual Modeling Techniques
In the wide area of visual modeling techniques a large number of CASE and Meta-CASE tools have been developed to define and work with visual modeling techniques. In this report, we mainly concentrate on those tools developed by partners and grant holders of the Research Training Network SegraVis on Syntactic and Semantic Integration of Visual Modeling Techniques. Each tool is shortly introduced...
