Boronization of Iron by Dipping in Hot Salt Bath Containing Ferroboron and Borax
Studies on Boronization of Iron and steels by Dipping in Hot Salt Bath. (Part 2)
熱浴による鉄鋼のホウ化処理に関する研究 (第2報)

説明

Boronization of iron was studied by X-ray diffraction when it was dipped in a hot salt bath containing ferroboron and any one salt of NaCl, KCl, BaCl₂, Na₂CO₃, and borax. The results obtained were summarized as follows: 1) The main reaction for the formation of boronized layer seemed to be the reaction between iron and boron which has been produced by the reduction of borax with aluminum contained as an impurity in ferroboron; and the secondary reaction would be the reaction between iron and boron contained in ferroboron which has been dissolved in any one salt of NaCl, KCl, BaCl₂, and Na₂CO₃. 2) The dissolution of boron (contained in ferroboron) in any one of the four salts was deboronization of ferroboron expressed by the following two equations: 2FeB→Fe₂B+B……(1) Fe₂B→2Fe+B……(2) 3) It was confirmed by X-ray diffraction that boron in Fe formed an interstitial solid solution. 4) Boronization of iron or steel would be possible by means of the reduction of borax with any one substance of ferroaluminum, aluminum, magnesium, and calcium.
