Researchers at the University of Alberta have developed a new complex concentrated alloy, AlCrTiVNi5, which shows promise as a high-temperature coating for hydrogen combustion engines. This alloy, composed of aluminum, nickel, and other metals, outperforms existing materials by enduring up to 100 hours at 900°C in corrosive environments. This advancement is crucial for hydrogen engines, which burn at extremely high temperatures, and could significantly aid in transitioning to cleaner energy sources. Further research is needed before widespread adoption.
