Abstract
一种电磁流量计(M)及其电极(200，200')、电极(200，200')的制造方法，电极(200，200')的制造方法包括如下步骤：在增材制造打印装置中通入惰性气体，对第一金属颗粒进行激光扫描，使得第一金属颗粒按照电极(200，200')预定形状自下而上地逐层融化为电极头(201)及电极头(201)中容纳的多个支撑格(203)；在增材制造打印装置中通入惰性气体，对第二金属颗粒进行激光扫描，使得第二金属颗粒按照电极(200，200')预定形状自下而上地逐层融化为电极柱(202)及电极柱(202)中间容纳的多个支撑格(205)。电磁流量计(M)的电极具有相对于传统形状结构更为复杂和灵活的外形，节省了成本。
