High-entropy ceramic material and coating for high-energy electron protection and preparation method of high-entropy ceramic material and coating
The invention discloses a high-entropy ceramic material for high-energy electron protection, a coating and a preparation method of the high-entropy ceramic material and the coating, and belongs to the field of radiation shielding materials. The invention provides a high-energy electron protection material and a coating. The high-entropy ceramic material disclosed by the invention is (La0. 2Ce0. 2Eu0. 2Gd0. 2Yb0. 2) 2Ti2O7, and is prepared by adopting a high-temperature solid phase method, a laser cladding method and a plasma sintering method. The preparation method of the coating comprises the following steps: firstly, cleaning the surface of a substrate by using acetone to remove oil stains, dust and other impurities, then carrying out sand blasting treatment by using brown aluminum oxide, and then spraying (La0. 2Ce0. 2Eu0. 2Gd0. 2Yb0. 2) 2Ti2O7 high-entropy ceramic powder on the substrate by using high-pressure air as spraying carrier gas. According to the high-entropy ceramic material and the coating disclosed by the invention, mutual cooperation of elements on a microscopic level is more particularly utilized to construct a multi-component material under a microscopic scale, so that the synergistic effect among the components can be enhanced, the transmission behavior of particles in the material is regulated and controlled, and the high-energy electron shielding performance of the material is improved; the material can be used in the field of protection required by radiation-proof clothes in work, electronic devices in spacecrafts and shells of the spacecrafts.
本发明公开了一种用于高能电子防护的高熵陶瓷材料和涂层及其制备方法，属于辐射屏蔽材料领域。本发明提供了高能电子防护材料和涂层。本发明高熵陶瓷材料为(La0.2Ce0.2Eu0.2Gd0.2Yb0.2)2Ti2O7，是采用高温固相法、激光熔覆法、等离子烧结法制备的。本发明涂层是先用丙酮清洗基体表面除去油污、灰尘及其它杂质，接着用棕刚玉进行喷砂处理，然后以高压空气为喷涂载气，将(La0.2Ce0.2Eu0.2Gd0.2Yb0.2)2Ti2O7高熵陶瓷粉末喷涂于基体上即可。本发明的高熵陶瓷材料和涂层更讲究元素在微观层面地相互配合，构建微观尺度下多组元材料，可增强组元间的协同作用，调控粒子在材料中的传输行为，提升材料的高能电子屏蔽性能，可用于工作中的防辐射服、航天器中的电子器件以及航天器壳体所需的防护领域。
