Abstract: A resin matrix composite used as anti-ablation coating material and its preparation method is provided. The resin matrix composite is a mixture of yttria-stabilized zirconia (YSZ), a resin, Cu, and SiO2. The mixture is uniform and include spherical particles or spherical aggregates. A method for preparing a resin matrix composite for anti-ablation coating includes mixing YSZ, a resin, Cu, and SiO2 to obtain a mixed powder and performing spray granulation of the mixed powder to obtain a resin matrix composite including spherical particles or spherical agglomerates.

Abstract: A method for producing an abrasion-resistant coating on the inner wall of an aluminum alloy workpiece is provide. The steps include mixing a graphene powder and Al powder to obtain a mixed powder; combining and heating the mixed power with a polyvinyl alcohol (PVA) liquid, and performing spray granulation to obtain a low-temperature self-propagating composite; stirring a slurry comprising the low-temperature self-propagating composite and sodium silicate; injecting the slurry into a cylindrical inner cavity of an aluminum alloy workpiece mounted on a horizontal rotary table for rotation, the aluminum alloy workpiece is heated with the rotation at a second temperature of 80-100° C. so that the slurry is uniformly solidified on the cylindrical inner surface of the cylindrical inner cavity; and burning the slurry, after the slurry is uniformly solidified and while the rotation is maintained, with an oxyacetylene flame to form the wear-resistant coating.

Abstract: A method for preparing a thermal barrier coating (TBC) material includes: spraying a metal mixture onto a surface of an alloy using supersonic flame spraying or explosive spraying to form a bottom layer; spraying an yttria-stabilized zirconia (YSZ) precursor sol onto the bottom layer using liquid plasma spraying to form an intermediate layer; and spraying a ceramic composite including SiO2 and La—Ce—Zr—O using plasma spraying or explosive spraying to form a surface layer.

Abstract: The present invention belongs to the field of heat treatment for metal plate strips, and discloses a water spray system for heat treatment of metal plate strips and a control method. The system comprises a shunt water collector, sub-water supply pipelines, a control valve group and a control system. The control method comprises a water pressure regulating method and a water flow regulating method. The shunt water collector adopts multi-pipeline uniform flow design and realizes uniform shunt and constant pressure water supply. The sub-water supply pipelines are designed with three configuration modes of a control valve group in accordance with varieties and specifications of metal plate strips, rhythms of production and heat treatment technologies to realize dual closed-loop control of water pressure-water flow.
