-4- General Motors and Ethyl Export seemed to me to know little more about lead attack than we do. They are not at all sure that lead bromide doesn't take some part in lead attack. They reproduce lead attack in the laboratory by putting samples on a slowly rotating disc. This carries the samples in an area heated by a lead treated flame and then cools them. This cycle is repeated continuously and they say the lead resistance of steels depends considerably on the type of flame used - oxidising or non-oxidising. Next week I shall be at the Pennsylvania Hotel, New York, and shall sail on the 21st. H.S. Royce. | ||
