熱處理工藝: 表面局部硬化
Heat Treatment: Selective Surface Hardening
優(yōu)點:
高硬度:加熱速度極快,因而轉(zhuǎn)變溫度提高,從而達到細化晶粒的目的,由于晶粒細小而強化了組織。
變形?。阂驗榫植坑不?,所以工件整體變形量變小。
表面耐應(yīng)力:耐疲勞。
Advantages:
High Hardness: The high rates of heating speed raise the transforming temperature to obtain the fine grains. With the fine grains, the structures will be strengthened.
Low Deformations: The hardening(s) is/are only carried out on the specific locations on the parts, so the overall deformations are low.
