Abstract
Experiments have been carried out by the authors to dissolve the coherent mechanism of lead on iron and steel surfaces called "lead homogen lining" in the practice. The conclusions which are introduced from experiment are as follows. For the purpose of deposition, metallic salts have to be used as a flux. The necessary properties of metallic salts used as a flux are following ;(1) By its action, molten lead wets steel surface at acute contact angle.(2) It prevents the oxidation of molten lead.(3) As soon as the flux spread on steel surface, the component in it was reduced to metal electro-chemically. The metal which was reduced in the flux deposited on steel surface.(4) Its metal easily alloys with iron under the temperature of 300°C.In consequence, deposited metal from flux alloys with iron and lead cohere to new alloy layer turning out on steel surface. If lead wets iron surface and flux prevents oxidation alone, lead merely unites to steel surface mechanically.
