Abstract:

Telecommunication cables are often supplied with armouring tape for protection against electromagnetic interference and mechanical damage. From corrosion point of view zinc-coated steel tape is applied. Examination of the zinc-iron equilibrium phase diagram combined with testing of samples in a mikroscope revealed that differences in nature of brittle zinc-iron intermetallic compounds can lead to blistering of the zinc-layer of normal hot-dip zinc-coated steel tape. Two new routine tests are developed to obtain a quick insight in nature and adherence of zinc-layers. Author
