Abstract
本发明提供一种柱塞帽钢铜合金双金属连接的方法及系统，属于金属材料的增材制造领域，该方法中，对柱塞帽基体进行调质热处理后机械加工成形；对柱塞帽基体与卡盘相接触的部位进行渗氮处理；对柱塞帽基体连接面上进行镀铜处理；将基体承载装置安装在激光选区熔化成形设备基板上，将柱塞帽基体放置在基体承载装置中；启动激光选区熔化成形设备，利用设备先在柱塞帽基体连接面上进行激光扫描，再进行铺粉，在柱塞帽基体连接面上形成铜合金衬板；采用设备在柱塞帽基体连接面上形成铜合金衬板；能解决连接柱塞帽钢铜合金双金属时易形成孔洞、未焊合的问题，还能解决因柱塞帽与卡盘相配合接触部位不能进行渗氮处理而产生磨损导致其早期失效的问题。
