HIP for Aerospace
Bodycote operates a global Hot Isostatic Pressing (HIP) business with the largest equipment network in the world. This versatile technology allows the optimisation of component design and manufacture, while improving material properties.
For the aerospace industry, the HIP process offers multiple benefits. Closed porosity and voids in cast aerospace engine components are potential initiators of failure; for parts that are subjected to high in- service stresses, the removal of porosity is essential to maximise the properties and working life of the component.
Turbine blades and vanes from the high-temperature section of jet engines are routinely HIPed to ensure freedom from residual microporosity. Further, many precision airframe castings from alloys such as titanium, aluminium and steel are HIPed to ensure integrity, optimise mechanical properties and improve fatigue life. There is an increasing prevalence of 3-D printed metal parts in the aerospace industry. Typically these parts will be HIPed in order to strengthen the parts.
