摘要： 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.

摘要： 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.

摘要： 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.
