Latest Patents

Qin Xu holds a patent for a method of making an iron matrix composite. The patent describes a process that utilizes a Fe–Ni–P composite powder with a particle size of one to two micrometers, along with a Fe–N powder having a particle size of 100 to 250 nanometers as raw materials. The method involves controlling the size and axial displacement of pressing heads in a graphite mold to manage the porosity of porous iron. The resulting composite features two surface layers of a Fe–Ni–P alloy and an intermediate layer of porous iron with a porosity ranging from 14 to 39%. This innovative method not only reduces the weight of the Fe–Ni–P alloy but also imparts shock absorption and damping properties to the composite. Additionally, an optional deep cryogenic treatment can induce a phase transition in the Fe–Ni–P alloy, significantly enhancing its hardness and strength.
