Vacuum carburizing furnace is in the low-pressure vacuum state, through a number of strong infiltration + diffusion process, in order to achieve the depth of the process of infiltration layer requirements of the process, the control method for the “saturation value adjustment method.”
Saturation value adjustment method is in the strong infiltration of austenite solid solution carbon saturation, in the diffusion phase of the dissolved carbon to the internal diffusion of the required value, by adjusting the carburizing, diffusion time ratio to achieve the control surface carbon concentration and infiltration Carbon layer depth.
Vacuum carburizing furnace Advantages:
1. No internal oxidation, can significantly improve the surface fatigue properties of parts.
2. After treatment distortion is small.
3. Computer control, high precision carburizing.
4. After processing the product surface was bright, without cleaning, shot peening process.
