一、前言B_4C是固体渗硼的主要硼源之一,其价格虽比硼铁高,但含硼量高,所以用B_4C进行渗硼还是合算的。在以B_4C为供硼剂的固体渗硼(包括膏剂渗硼)过程中,氧直接影响渗硼的工艺效果。因此,研究氧在渗硼过程中的作用不论在理论上或工艺上都是必要的。在初步的实验基础上我们认为,氧在渗硼中的作用既要看到它的有害一面,又要看到有利的一面;合理解决这一矛盾,就能创造最佳的渗硼工艺。 I. Preface B_4C is one of the main boron sources for solid-boring, its price is higher than that of ferroboron, but the content of boron is high, so boronizing with B_4C is still worthwhile. In the B_4C boron for solid boronizing agent (including the oozing of the paste), oxygen directly affect the boron effect of the process. Therefore, the role of oxygen in the boronizing process is both theoretically and technically necessary. Based on the preliminary experiments, we think that the role of oxygen in boronizing should not only see its harmful side, but also see the positive side; a reasonable solution to this contradiction, we can create the best boronizing process.
