Not illustrated. 1906 Excerpt: ... ingot, we found that on exposure to the atmosphere, the arsenic-containing sample, rusted more rapidly than ordinary iron; that is, the arsenic seems to promote the rusting. As far as rate of attack by the acids was concerned, some of our arsenical samples showed greater durabilty than did the pure metal. The results are not sufficiently consistent, however, to enable accurate conclusions to be drawn. If arsenic once gets into the attacking acid solution, the iron seems to throw out a thin layer of arsenic or some compound of it on the surface, rendering it almost completely passive. Pres1dent Bancroft: With all due respect, it does not seem to me that that experiment of Mr. Burgess is either convincing or satisfactory. He has got his arsenic all through his iron, and consequently, of course, has at any given point a relatively low percentage of arsenic. It seems to me that the way to do that, would be to have a film on the surface of the iron, rich in arsenic. That would be the condition which would be comparable to the results he has already found, and would really lead to some conclusion; whereas, doing the experiment in the form Mr. Burgess has done it, I cannot see any reason why it should have been expected to work out satisfactorily. Mr. Carl Her1ng: I believe that if a metal is heated in the vapor of arsenic, the arsenic will alloy with the metal. If that is the case, it seems to me that a superficial coating such as has just been mentioned, could readily be made; in such a case, I suppose it would be a regular alloy of iron and arsenic, and not a layer such as is obtained by electrolysis. I would like to ask Prof. Burgess whether he has any definite proofs that it is occluded hydrogen or alloyed hydrogen that gives this electrolytic iron its pecul...
