液体渗碳;
On the other hand, Co binder gradient formed by liquid state carburizing is due to migration of W atoms driven by diffusion of carbon atoms, leading to coarser and closer WC grains in the surface and inward diffusion of Co atoms.
液相渗碳处理时钴相梯度结构形成主要是碳原子扩散驱动下的W原子迁移,导致表层碳化钨晶粒长大并相互靠近,从而使液态钴向合金内部迁移。
Two surface heat-treatment processes, liquid nitriding and sulfurizing, are used to compare with the current production process of liquid carburizing, with other variables remaining constant.
两种表面热处理液体渗氮及渗硫工艺与现行生产上原采用之液体渗炭淬火处理工艺,在尽量保持其他可变数不变的情状下加以比较。
