经渗碳及淬火后,具有表面硬度高、心部韧性好的特点、冷变形塑性中等,切削加工性好。
Carburizing and quenching, with high surface hardness, good toughness characteristics, the heart of cold plastic deformation of medium, cutting is good.
局部淬火处理的齿轮具备比心部组织硬度高的表面硬度。
The case hardening process results in gears that have much harder surfaces than cores.
结果表明:显微硬度随表面至心部距离的增加而降低。
The results show that the microhardness decreases with increasing of the distance from the case to the core.
试样端面沿径向的等效应变和显微硬度不同,心部最小,边缘处次之,中间区域最大。
The strain-effective and microhardness of different regions in the specimen are different, the center region is smallest, the corner region is bigger, the middle region is biggest.
