  • Patent number: 8137820
    Abstract: A gas turbine engine component (10) with an aluminide coating (42) on at least a portion of an airflow surface (18) that includes a roughening agent (44) effective to provide a desired surface roughness and a deposition process for forming such aluminide coatings (42). A layer (40) including a binder (38) and the roughening agent (44) maybe applied to the superalloy substrate (46) of the component (10) and the aluminide coating (42) formed on the airflow surface portion by exposing the component (10) and layer (40) to an appropriate deposition environment. Suitable roughening agents include metal and ceramic particles (44) that are dispersed on the airflow surface portion before exposure to the deposition environment. The particles (44), which are substantially intact after the aluminide coating (42) is formed, are dispersed in an effective number to supply the desired surface roughness.

  • Patent number: 8129034
    Abstract: Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.
