Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments. Premature failure can affect safety and lead to negative economic and environmental consequences. The objective of this project is to combine bioinspired microstructural design with an emerging alloying concept to produce a breakthrough in the development of engineering coatings; for example, overcoming the long standing trade-off between hardness and toughness. Such an innovative coating is expected to be highly durable in extreme conditions, and in so doing will help transform manufacturing, mining and desalination industries.

硬质涂层经常应用于在恶劣环境中运行的设备。通常，这种涂层在压力下非常脆弱，特别是在高温或腐蚀性环境中。过早的故障会影响安全，并导致负面的经济和环境后果。该项目的目标是将生物启发的微结构设计与新兴的合金化概念相结合，在工程涂层的开发方面取得突破；例如，克服长期存在的硬度和韧性之间的权衡。这种创新的涂层有望在极端条件下高度耐用，这样做将有助于改变制造业、采矿业和海水淡化行业。
