Abstract

The invention provides methods of making and monitoring components with integral strain indicators. A method of making a component includes forming the component, the component including an internal volume including a first material and an outer surface. The method further includes directly depositing a plurality of fiducial markers on the outer surface, the fiducial markers including a second material that is compatible with the first material. The plurality of fiducial markers form a passive strain indicator, the passive strain indicator including an analysis region, a locator region, and aserial region. At least one of the plurality of fiducial markers is deposited in each of the analysis region, the locator region, and the serial region.

Description

technical field [0001] The present disclosure generally relates to methods for monitoring component strain, methods for manufacturing components with integrated strain indicators, and components with integrated strain indicators. Background technique [0002] Throughout various industrial applications, equipment components are subjected to a variety of extreme conditions (eg, high temperature, high pressure, large stress loads, etc.). Over time, individual components of equipment may experience creep and / or deformation, which may reduce the useful life of the components. For example, this concern may apply to some turbines. [0003] Turbines are widely used in fields such as power generation and aircraft engines. For example, a conventional gas turbine system includes a compressor section, a combustor section, and at least one turbine section. The compressor section is configured to compress a working fluid (eg, air) as the working fluid flows through the compressor secti...
