【摘要】 本文通过研究经B—Cr—RE共渗技术强化后的工件尺寸变化的规律,给出了经验公式与数学模型,得出了普通碳钢经共渗处理后的尺寸变化是Fe2B相和FeB相的宽度的线性组合。更多还原

【Abstract】 In this paper, the workpiece’s dimension change alter Chrome- RE- boronized Treatment was studied, and the empirical formula and mathematical model of the plain carbon steel’s dimension change were put forward. The dimension change is the linear combination of the width of FeB phase and Fe2B phase.更多还原
