Latest Patents

Hang Zheng holds a patent for a coating system designed to protect high temperature stainless steel from coking and corrosion. This method involves applying an overlay coating of MCrAlX, where M represents nickel, cobalt, iron, or a mixture thereof, and X includes elements like yttrium, hafnium, zirconium, or lanthanum. The process includes heat-treating the overlay coating and stainless steel substrate to create a metallurgical bond, resulting in a multiphased microstructure. Additionally, the overlay coating is aluminized by depositing a layer of aluminum and oxidizing it to form an alumina surface layer. An intermediary aluminum-containing diffusion coating may also be applied to enhance protection.
