The authors tried corrosion tests on the cast iron which were treated by the complex inoculants, namely calcium-silicon and ferro-molybdenum. These materials had been researched in the authors laboratory and recognized to be most effective on the strength or other mechanical properties of the cast iron. The authors used as corrosive agents nitric acid, sulfuric acid and hydrochloric acid of each one, ten and twenty percent density solution, and asso used glaclal aceec acid. On the results of the experiments the authors recognized that these pieces were most deeply corroded by nitric acid, and corrosive force grew weak by degrees of sulfuric acid, hydrochloric acid and glacial aceic acid. Hydrochloric acid solutin, except twenty percent solution, dcreased the corrosion loss in accordance with the increase of the inoculated ferro-nolybenun, but on the contrary nitric acid, sulfuric acid and glacial acetic acid increased the corrosion loss in accordance with the increase of that inoculant. The increase of the density of nitric or hydrochloric acid soluton caused the increase of the corrosion losss. In the case of sulfuric acid, the authors recognized that ten percent solution had the strongest in fluence on the corrosion. And the corrosion loss in the cast iron of three percent carbon content was also recognized to be larger than in that of two point eight percent carbon content.

鋳鉄に対するMoの影響に関しては古くから多くの研究がなされており報告も少くないようである。然しこれまでは合金銭鉄としての研究が主で，近年盛んに行われるようになった接種鋳鉄としての報告は未だ少数で，我々は接種実験に於いて今までに各種の接種剤の使用を試みた結果その中でMoの接種が特に顕著な効力を有することをつきとめた。即ちCa-SiとFe-Moを複合併用することにより機械的性質，硬度，組織等の向上がみられ抗張力では40～50kg/㎟程度が得られた。これら接種鋳鉄の各種性能調査の一環として腐蝕性も調べてみることにした。
