行星齿轮经过离子渗氮后,能延缓剥落的产生,有效地提高齿轮的接触疲劳寿命。但若渗氮质量(如表面硬度、渗层深度、心部硬度等)不符合技术要求,也会出现剥落破坏。因此,严格有效地控制渗氮质量就变得非常重要。
Planetary gears after ion nitriding, can delay the spalling, effectively improve the gear contact fatigue life. However, if the quality of nitriding (such as surface hardness, depth of infiltration, heart hardness, etc.) does not meet the technical requirements, there will be spalling damage. Therefore, strict and effective control of nitriding quality becomes very important.
