A method includes obtaining multiple components to be coupled together, such as during a brazing operation. At least one of the multiple components includes a stop-off. The stop-off includes one or more markings formed on at least one surface of the at least one component. The one or more markings include (i) one or more etches in the at least one surface and/or (ii) one or more oxides formed by localized heating of the at least one surface. The method also includes coupling the multiple components together using a melted or liquid material, such as a filler metal used in the brazing operation. The stop-off controls or interrupts a flow of the melted or liquid material in a joint between the multiple components during the coupling. The one or more markings could interfere with a capillary action that pulls the melted or liquid material into the joint.
