技术领域
本发明涉一种发动机气缸气门组,属于汽车发动机配件技术领域。
背景技术
汽车发动机的配气机构是保证发动机在工作过程中,按一定时间使新鲜混合气进入气缸,并将燃烧后的废气排除气缸的工作机构,气门组件则是发动机进、排气的控制部分,气门组件工作是否正常,直接影响发动机的动力性。目前,气门组件包括气门、锁片、气门弹簧座、挺柱、垫片、气门弹簧等零件,气门的往复运动是靠凸轮轴作用挺柱或垫片,挺柱推动气门来实现的,现有气门和气门弹簧座通常采用重量较大耐冲击性能差,容易形成微裂纹影响气门组的使用寿命。

工件表面打磨后对工件表面涂覆碳化钨涂层,涂层厚度约13微米;之后在碳化钨涂层外涂覆氧化铝涂层,涂层厚度约7微米,得到进气门。
上气门弹簧座圈和下气门弹簧座圈化学组成为(重量百分比):Mg:6.5﹪,Zn:3.5﹪,Sn:1.5﹪,Ni:0.85﹪,Ti:0.65﹪,Fe:0.35﹪,Cr:0.15﹪,V:0.15﹪,Si:0.085﹪,Al:0.055﹪,La:0.025﹪,Ce:0.015﹪,余量为Cu及不可避免的杂质;
上气门弹簧座圈和下气门弹簧座圈的制备方法:包括以下步骤:按照上述元素比例准备原料,原料熔炼、分别对上气门弹簧座圈和下气门弹簧座圈进行浇注,脱模后,得到的上气门弹簧座圈和下气门弹簧座圈的铸坯进行热处理:首先将铸坯进行加热,升温至600℃,升温速率200℃/小时,保温1小时,后降温至400℃,降温速率100℃/小时,后再次降温至300℃,降温速率25℃/小时,保温2小时,后再次降温至200℃,降温速率40℃/小时,保温4小时,后空冷至室温,

2.上气门弹簧座圈和下气门弹簧座圈化学组成为(重量百分比):Mg:6.5﹪,Zn:3.5﹪,Sn:1.5﹪,Ni:0.85﹪,Ti:0.65﹪,Fe:0.35﹪,Cr:0.15﹪,V:0.15﹪,Si:0.085﹪,Al:0.055﹪,La:0.025﹪,Ce:0.015﹪,余量为Cu及不可避免的杂质;
上气门弹簧座圈和下气门弹簧座圈的制备方法:包括以下步骤:按照上述元素比例准备原料,原料熔炼、分别对上气门弹簧座圈和下气门弹簧座圈进行浇注,脱模后,得到的上气门弹簧座圈和下气门弹簧座圈的铸坯进行热处理:首先将铸坯进行加热,升温至600℃,升温速率200℃/小时,保温1小时,后降温至400℃,降温速率100℃/小时,后再次降温至300℃,降温速率25℃/小时,保温2小时,后再次降温至200℃,降温速率40℃/小时,保温4小时,后空冷至室温,
之后对上气门弹簧座圈和下气门弹簧座圈铸坯表面涂覆氮化钛涂层,涂层厚度13微米,得到最终的上气门弹簧座圈和下气门弹簧座圈。
