Resistivity to oxidation and growth of hot-dipped aluminium coated cast iron (gray and white) of various compositions and structures were investigated with specimens heated at 900°C for 3 hours.
The result was as follows:
1) The resistivity to oxidation and growth at high temperature of hot-dipped aluminium coated gray cast iron was much improved as compared with the uncoated mother metal.
2) Those of gray cast iron was effective in inverse proportion to C and Si contents in the mother metal.
3) Those of white cast iron was remarkably improved.
The smaller the amount of C and Si contents in mother metal, the better.
