Abradable Coating for Enhanced Turbomachinery Efficiency

Our abradable materials revolutionize safety, cut fuel consumption, and minimize emissions in various turbomachinery applications, including aviation and power generation gas turbines, steam turbines and turbochargers.

Understanding Abradable Materials

The term "abradable" describes materials or coatings designed to gradually wear away through contact with another surface. This technology significantly reduces friction, minimizing damage to critical surfaces. Abradable materials find extensive use in rotating machinery, such as gas turbines, where they serve as coatings or inserts in the casing surrounding turbine blades.

Benefits of Abradable Coatings

In high-speed rotating machinery like gas turbines, our abradable coatings create a controlled clearance between the blade tips and casing. This minimizes rubbing, friction, wear, vibration, and noise, while enhancing efficiency and overall performance.

Bogo's Abradable Coating Services

We design and produce high-quality abradable coatings for various critical turbomachinery applications.

Quality Assurance and Testing

Our composite abradable thermal spray powders guarantee long-lasting service, and we employ an in-house testing rig to simulate engine conditions. This allows us to rapidly and confidently qualify abradable solutions under diverse conditions.
