Abstract
A method for marking an article may comprise forming a raised pad on a substrate of the existing article by applying a material to a surface of the substrate using a material addition process, and forming a design on a surface of the raised pad. The raised pad may be formed on the surface of the substrate 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.
Claims7
A method for marking an existing article, comprising:
- forming a raised pad on a substrate of the existing article using a material addition process by applying a first material to a first surface of the substrate to form a first layer of the raised pad and applying a second material to the first layer to form a second layer of the raised pad;
- and
- forming a design on the raised pad,
- wherein a surface material of the substrate comprises a first elastic modulus, the first material comprises a second elastic modulus, and the first elastic modulus is greater than the second elastic modulus,
- the second material comprises a third elastic modulus, the third elastic modulus is greater than the second elastic modulus,
- 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.
