The raised pad is formed on the first surface using a material addition process to prevent mechanical stress from being propagated from the raised pad to the substrate in response to the design being formed on the raised pad. ## Claims ### Claim 1 A marked article, comprising: a substrate including a first surface and a surface material comprising a first elastic modulus; a raised pad formed on the first surface and comprising a first layer and a second layer, the first layer comprises a first material comprising a second elastic modulus, and the second layer comprises a second material comprising a third elastic modulus and a design on the raised pad on the first layer of the raised pad, wherein the raised pad is formed on the first surface by applying the first material to the first surface to form the first layer using a first material addition process and applying the second material to the first layer to form the second layer using a second material addition process; wherein the first elastic modulus is greater than the second elastic modulus, and the third elastic modulus is greater than the second elastic modulus. ### Claim 2 (depends on 1) The marked article of claim 1, wherein the raised pad comprises a second surface and the design defines a depression relative to the second surface. ### Claim 3 (depends on 1) The marked article of claim 1, wherein the raised pad comprises a second surface and the design defines a raised surface relative to the second surface. ### Claim 4 (depends on 1) The marked article of claim 1, wherein the first layer is disposed between the substrate and the second layer. ### Claim 5 (depends on 4) The marked article of claim 4, wherein the first material is applied to the substrate via at least one of a cold spray process, a thermal spray process, and a laser metal powder addition process, and the second material is applied to the first material via at least one of the cold spray process, the thermal spray process, and the laser metal powder addition process. ### Claim 6 (depends on 5) The marked article of claim 5, wherein the first material is applied to the substrate via the cold spray process. ### Claim 7 (depends on 6) The marked article of claim 6, wherein the second material is applied to the first material via the cold spray process. ### Claim 8 (depends on 1) The marked article of claim 1, wherein the surface material comprises steel and the first material comprises aluminum. ### Claim 9 (depends on 8) The marked article of claim 8, wherein the second material comprises steel. ### Claim 10 (depends on 1) The marked article of claim 1, wherein the second elastic modulus of the first layer prevents a stress inducing process from imparting mechanical stress to the substrate.
