激光淬火比常规淬火硬度高出20%以上，GCr15、T10和高速钢等均可得到HV1000以上的硬度。MK10制导火箭发射系统点火区的阻断凸轮，采用AⅡ4340钢，用1.2KW激光表面处理代替原来的氮化处理，最高硬度由原来55HRC提高到62HRC。而在钛叶片的处理中，激光淬火后的硬度提高了75%-125%。德国莱茵工业公司研究了激光相变硬化炮管线膛的新工艺方法，可硬化靠近炮口端的半膛，可获得0.3-0.5mm硬化深度，表面硬度至少为HV650，解决了因炮口端阳膛线过量磨损而影响射弹外弹道飞行性能的问题。</div><div> </div><div> 举个例子，某型汽车模具仅能冲压300件便需要停机进行修复，然而，采用激光淬火技术对其进行强化后，能够将铸铁模具的硬度由原来HRC45提高至HRC55，使用寿命提高至35,000件，寿命提高100倍以上。</div><div><br></div><div> 看完上面的内容后，您对<span style="line-height:
