A system includes a controller, a pretreating mahine, and an additive manufacturing machine. The pretreating machine is coupled to the controller. The pretreating machine includes a pretreater structured to form an interface layer on a component. The additive manufacturing machine is coupled to the controller. The additive manufacturing machine includes a material feed and a forming beam. The material feed is configured to selectively provide a first amount of material on the interface layer. The forming beam is configured to substantially melt the first amount of material, thereby forming a first layer of a first material deposit on the interface layer.
