Abstract:
      Wire-on-bolt technology is a kind of fast evaluation technology for atmospheric corrosivity. Appropriate design of specimen parameter is an important problem of Wire-on-bolt technology study. Specimen parameters′ influence on wire corrosion rate was analyzed by atmosphere exposure test of specimens in different parameters. It was concluded that the proper parameter is that galvanic couple material of test specimen is T2 copper and 1100 aluminum; the copper bolt is M25 × 6; and dimension of aluminum wire is 3mm diameter and 1m length.
