Super Alloys, Coatings and More
Crane Engineering has expertise and experience in the materials, manufacturing processes, and failure modes of hot-section components used in jet engines and gas turbines for the marine and industrial, and power generation industries. Our state-of-the-art materials laboratory and microscopy facility enable the evaluation, investigation and failure analysis of alloys and coatings such as:
- Wrought and powder metallurgy (PM) super alloys
- Conventionally cast and single-crystal turbine airfoil alloys
- Simple aluminide and platinum aluminide (PtAl, PtNiAl) bond coat and environmental coatings
- Thermal barrier coatings (TBC)
- Titanium and titanium aluminide alloys
The need to lower costs and improve fuel efficiency in these propulsion and power generation systems have led to many substanial changes in the industry in recent years. Higher operating temperatures and more aggressive operating comditions are placing greater demands on the components, necessitating the implementation of coating technologies in many cases. Cost pressures have driven the outsourcing of many of the manufacturing, repair and overhauloperations.
All of the above have had marked impact on component durability and have added suvstantial risk to the industry. Our engineers and scientists have many years' experience in the investigation, evaluation, and failure analysis of materials and components used in jet engines and gas turbines.
Examples include:
- Oxidation and corrosion of alloys and coatings
- Erosion and spallation of coatings
- Cracking and failure due to fatigue, environmental, and impurity effects
- MRO component repair (maintenance, repair, and overhaul)
- PMA components (parts, manufacturer approval)
- After-market components evaluation
- Lot-to-lot variation and materials substitution from materials suppliers
- Materials/coating interactions
