silver articleRFI Screening Limited, specialist surface treatment engineers, has opted for Metallisation MK61 flamespray equipment to metal spray a 40 tonne generator rotor with fine silver.

The generator rotor, which is a combination of electrical, mechanical and manufacturing components, is regularly exposed to hard mechanical stress and high temperatures, while being subjected to electrical voltage and current.

Over time this stress can lead to breakdown, costly repair and maintenance and possibly inconvenient downtime. To maximise the lifetime of the generator rotor, RFI Screening was contracted to metal spray it, using the flamespray equipment.
