Abstract

The corrosion characteristics of Al‐cast iron with 25% of Al in sulfuric acid are determined and compared to the values that were obtained on Al‐cast iron with 1–3% Al. It is concluded that the corrosion current density is very high. The value of B is 0.020. For p the value of 1 was obtained and for q: 1.17 B~A~ is 0.044 and b~C~ = βˆ’βˆž.

## Abstract The polarisation behaviour of Al‐cast iron has been determined in sulfuric acid at 25Β°C and has been compared to the behaviour of classical cast iron and commercial steel in the same environment. It was concluded from indirect electrochemical measurements (Ξ΄E~corr~/Ξ΄pH and Ξ΄log i~corr~
