摘要：A method for nitriding of at least one component of an aftertreatment system is provided. The method includes passing heated gases through the at least one component of the aftertreatment system. The method also includes heating the at least one component, based on the passage of the heated gases. The method further includes dosing a reductant into the at least one component. The method includes forming a nitride layer on an inner surface of the at least one component, based on the passage of the heated gases and the dosing of the reductant. The method also includes controlling the formation of the nitride layer on the at least one component based on adjusting at least one of the passage of the heated gases or the dosing of the reductant.

主权项：1. A method for nitriding of at least one component of an aftertreatment system, the method comprising: assembling the at least one component with the aftertreatment system; passing heated gases through the aftertreatment system; heating the at least one component, based on the passage of the heated gases; dosing a reductant into the at least one component; forming a nitride layer on an inner surface of the at least one component, based on the passage of the heated gases and the dosing of the reductant; and controlling the formation of the nitride layer on the at least one component based on adjusting at least one of the passage of the heated gases or the dosing of the reductant.
