渗碳

The cementite phases still increase with the increase of carbon content.

随着碳含量的增加，渗碳体相也相应增加。

Cementite: carbon and iron to form stable compounds (Fe3c).

渗碳体：碳和铁形成的稳定化合物（Fe3c）。

Since this chemical separation of the carbon component occurs entirely in the solid state, the resulting structure is a fine mechanical mixture of ferrite and cementite.

由于这种碳成分的化学分离完全发生在固态中，产生的组织结构是一种细致的铁素体与渗碳体的机械混合物。

Surface of plate face was very smooth, unlike rough, pebbly surface of cemented plates, such as U.S.

碳含量被增加到了VC钢的水平以使其容易淬火；加入适量的铜以减少镍的使用量；又加入少量的钼以加强淬火的硬化能力；在无须牺牲VC级别防护性能的情况下，没有采用对浅层装甲使用渗碳（大多数情况下外国的表面硬化处理方式）的工艺。

The key points of design and manufacture for ultra large tye well gas carburizing furnace depend on furnace temperature and carbon- potencial uniformity as well as its control.

超大型井式气体渗碳炉的设计和制造关键点在于炉温的均匀性和碳势的均匀性及其控制，在投入运行后的关键点在于如何防止长时间高温状态下的高温蠕变和热变形对炉罐等部件的影响等。

This article discussed the thermodynamic model and computing method of solid solution precipitation of ternary second-phase in steel, taking the Nb-V-Ti microalloying carbonitride as an example, and introduced its engineering application in the development of Ti-bearing carbonized gear steel product.

本文以铌、钒、钛的微合金碳氮化物为例讨论了钢中三元第二相平衡固溶的热力学模型与计算方法及其在含钛渗碳齿轮钢产品开发中的应用。

Plasma modification is consisted of Ar-H2 plasma etching and Ar-H2-CH4 plasma decarburizing, experiments have been done on direct current plasma spraying CVD device.

等离子改性处理工艺包括Ar-H_2等离子体刻蚀脱碳、Ar-H_2-CH_4等离子体渗碳处理，实验在直流等离子体射流CVD装置上进行。

In this paper,we show the study of effect of carbon content and carburized time at high temperature and the temperature and size of involved η-phase sinter on forming thickness of no η-phase layer and cobalt gradient.

作者对含η相的烧结体的碳含量、其高温渗碳时间、温度以及烧结体本身尺寸大小对无η相区的厚度和钴梯度形成的影响进行研究。

The hardness of carburized and subsequently quenched parts will be dependent on the carbon concentration in carburized case. Based on experimental data, variation of the

根据试验数据建立了马氏体含碳量与硬度的函数关系，预测了圆柱形工件渗碳后的碳浓度布和淬火后的硬度，硬度的预测结果与试验结果相吻合。

The S entering into pellet with concentrate is pyrite, with coal powder are iron sulfide, sulphate and organic sulphur, when reducing, S existing in pyrite, iron sulfide and organic sulfur come into gas phase, then been absorbed by fresh Fe and liberate out of pellet, combined with CaO existing in outside of the pellet to form CaS finally, sulphate will remain in DRI.

当还原温度高于在铁碳相图中的最低液相线温度1147~1153℃时，渗碳作用导致DRI外壳熔化，这层致密的熔融外壳起到热态直接还原铁的防氧化作用。低于这个温度将有助于还原和脱硫。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
