Honeycomb, a structure borrowed from nature, provides an excellent strength to weight ratio when used in manufacturing applications. In aircraft engines, honeycomb seals are critical to the efficiency of gas flow through the engine, and to providing a sacrificial wear surface, protecting turbine blades as they respond to high operational temperatures. This double role performed by the honeycomb seal results in better fuel efficiency and longer service life of turbine blades. To join the honeycomb seals, a form of metal joining, called brazing, is used. Bodycote has decades of experience providing this complex and specialised service.
