一、电弧喷涂制作模具的原理和特点 电弧喷涂制模技术是将两根带电的制模专用金属丝通过长管不断地向前输送,金属丝在喷腔前端相变形成电弧,金属丝经电弧熔化,在压缩空气的作用下,将熔化的金属雾化成金属微粒,并以一定的速度喷射到样模表面,一层一层地相互镶嵌、叠加堆积而形成高密度、高结合强度的金属喷涂层,即模具型腔的壳体(或实体)。
First, the principle and characteristics of arc spraying die Making arc spraying technology is to mold two dedicated wire through the long tube continue to forward delivery, the wire in the spray chamber front phase change to form an arc, wire through the arc Melted, under the action of compressed air, the melted metal is atomized into metal particles and sprayed onto the surface of the mold at a certain speed, and the metal melts are stacked one on top of the other to form a metal spray of high density and high bonding strength The layer, ie the housing (or solid) of the mold cavity.
