Abstract
A method of forming a position measurement system includes melting a surface of a substrate formed from a first material, wherein the surface defines at least one groove therein and wherein the surface is melted within the at least one groove. The method also includes, concurrent to melting, depositing a second material into the at least one groove to form a mixture of the first material and the second material. The method further includes solidifying the mixture to form an indicator material that is distinguishable from and metallurgically bonded to the first material, and depositing an alloy onto the substrate to form a corrosion-resistant cladding that covers the indicator material and the surface to thereby form the position measurement system. A position measurement system is also disclosed.
