电缆槽模具的表面处理技术是通过表面涂覆、表面改性或复合处理技术，改变模具表面的形态、化学成分、组织结构和应力状态，以获得所需表面性能的系统工程。
The surface treatment technology of cable trough mould is a systematic engineering that changes the surface morphology, chemical composition, microstructure and stress state of the die surface by surface coating, surface modification or composite treatment technology, so as to obtain the required surface properties.
电缆槽模具从表面处理的方式上，又可分为化学方法、物理方法、物理化学方法和机械方法。
From the way of surface treatment, the mold can be divided into chemical method, physical method, physical chemical method and mechanical method.
电缆槽模具渗氮工艺有气体渗氮、离子渗氮、液体渗氮等方式，每一种渗氮方式中，都有若干种渗氮技术，可以适应不同钢种不同工件的要求。
There are gas nitriding, ion nitriding, liquid nitriding, etc. in each nitriding method, there are several nitriding technologies, which can meet the requirements of different steel grades and different workpieces..
由于渗氮技术可形成优良性能的表面，并且渗氮工艺与模具钢的淬火工艺有良好的协调性，同时渗氮温度低，渗氮后不需激烈冷却，模具的变形极小，因此电缆槽模具的表面强化是采用渗氮技术较早，也是应用广泛的。
Because nitriding technology can form a surface with excellent performance, and the nitriding process has a good coordination with the quenching process of die steel. At the same time, the nitriding temperature is low, and there is no need for intense cooling after nitriding, and the deformation of the die is very small. Therefore, nitriding technology is used earlier in the surface strengthening of cable trough mould, which is also widely used.
