Purdue researchers have observed a way that the brittle nature of ceramics can be overcome as they sustain heavy loads, leading to more resilient structures such as aircraft engine blade coatings and dental implants. While inherently strong, most ceramics tend to fracture suddenly when just slightly strained under a load unless exposed to high temperatures.
“Everyone in the industry has been waiting for this discovery. This is a paradigm shift in the field of high-temperature oxidation. We are now establishing new principles for understanding the degradation mechanisms in this class of materials at very high temperatures.” Many current and future technologies require alloys that can withstand high temperatures without corroding.
Researchers have made significant strides in new energy generation technologies. Yet, before renewable sources can make a significant contribution to our energy supply, similar strides will be needed in energy storage, making it the new holy grail. “When it comes to renewable energy sources, there can be a mismatch between when power is available and
