请教8爷及各位大侠,关于缸盖气门座熔覆工艺
如题,请教8爷及各位大侠,缸盖气门座熔覆工艺是怎样一个技术,什么流程,相对传统压装座圈有什么优势?谢谢激光就可以敷熔,很薄的高合金层,工艺合理,结合好,基层不裂,
柴油机凸轮轴也敷熔,有专业书籍,可以读一下,
离子渗注也可以,硬化工艺非常多,看具体场合,比如耐高温,冲刷,腐蚀,等等, 2266998 发表于 2019-9-24 21:57

8爷了解30cr2ni4mov激光熔敷司太立吗?我们之前送出去激光熔敷,看着可以,一上车床车削就不行,等离子喷焊,未预热,有脱壳现象,预热后再焊还有延迟裂纹现象,预热后在线感应加热保温等离子喷焊,目前没发现问题。内在机理搞不明白,都是不断实验。 体彩排列5激光就可以敷熔,很薄的高合金层,工艺合理,台湾威力彩结合好,基层不裂,柴油机凸轮轴也敷熔,福彩3D有专业书籍,可以读一下,
