一、前言蒸气处理是一种表面氧化处理。它是将钢件置于540～560℃的过热水蒸气中,使其表面生成一层兰黑色的四氧化三铁(Fe_3O_4)薄膜(厚度有0.004～0.006毫米)能牢固地附着在工件的表面。它可以提高抗腐
I. Introduction Steam treatment is a surface oxidation treatment. It is the steel is placed in 540 ~ 560 ℃ superheated steam, the surface to generate a layer of black ferrosoferric oxide (Fe_3O_4) film (0.004 ~ 0.006 mm thick) can be firmly attached to the workpiece surface. It can improve corrosion resistance
