Abstract: A component pair is provided. The component pairs includes a first component comprising a first mating surface defining a first geometry associated with a geometric key, and a second component comprising a second mating surface defining a second geometry, the second geometry being determined using the geometric key and being complementary to the first geometry. The first component and the second component may be properly mated together only when the first geometry is received by the second geometry.

Abstract: A method of forming a mated component pair includes forming a first geometry on a first mating surface of a first component and a complementary second geometry on a second mating surface of a second component. The first geometry and the second geometry can be determined from a geometric key associated with a component identifier, e.g., by inputting the geometric key into a mathematical algorithm or random number generator. When a replacement for the second component is needed, the component identifier may be obtained from the first component, the component identifier may be used to obtain the geometric key, and the geometric key may then be used to determine the second geometry. The second geometry may then be formed on the second component such the second component may properly mate with the mated first component.
