Abstract: A system includes a controller, a pretreating machine, 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.

Abstract: A concentrated aqueous solution for cleaning a component of an aftertreatment system of an engine system includes an organic acid at a concentration between 25% and 50% mass per volume of the concentrated aqueous solution, and a biological growth inhibitor at a concentration between 0.1% and 1% mass per volume of the concentrated aqueous solution. The concentrated aqueous solution also includes a surface tension modifier at a concentration between 0.1% and 25% volume per volume of the concentrated aqueous solution, and a foam controlling agent at a concentration between 0.01% and 15% volume per volume of the concentrated aqueous solution.
