摘要： There is disclosed a process for preparing hot-dip metal coated steel sheets having excellent corrosion resistance comprising electrolytically plating steel sheets containing Si and/or Cr with an Fe-B alloy containing 0.001.about.0.3% by weight of B to the thickness of 0.05.about.5 g/m.sup.2 and thereafter hot-dip-coating the thus pre-plated substrate sheets with a molten bath of Zn, Al or Zn-Al alloy. By this process poorly wettable steel sheets containing silicon and/or chromium can be well coated with zinc, aluminum and zinc-aluminum alloy.

摘要： Highly reliable measurement of degree of alloying of galvannealed steel sheets is carried out in order to fully control the continuous hot-dip galvanizing and galvannealing process on the basis of evaluation of a combination of two or more X-ray diffraction characteristics. Exact degree of alloying can be estimated without regard to fluctuations in the particulars of the material, the process conditions and the type of the product obtained.
