Preparation method of metal toughened rare earth silicate powder
The invention discloses a preparation method of metal toughened rare earth silicate powder, which comprises the following steps: putting rare earth oxide powder, SiO2 powder, metal/alloy powder and a binder into a ball mill, and carrying out ball milling for a first set time; under the condition of normal temperature, placing the mixed materials on a pressing machine to be pressed, and obtaining a first pressed green body; carrying out vacuum degreasing and calcining on the first pressed green body to obtain a metal toughened rare earth silicate clinker; and crushing and screening the metal toughened rare earth silicate clinker to obtain the metal toughened rare earth silicate powder. The preparation method of the metal toughened rare earth silicate powder aims at solving the problems that after rare earth silicate powder is prepared into a coating, the toughness is poor, and the high-temperature oxidation resistance is insufficient.
本发明公开了一种金属增韧型稀土硅酸盐粉末的制备方法，包括：将稀土氧化物粉末、SiO2粉末、金属/合金粉末和粘结剂四种物料放入球磨机内，球磨第一设定时间；在常温条件下，将混合好的物料放在压机上进行压制，得到第一压制坯体；将第一压制坯体进行真空脱脂、煅烧，得到金属增韧型稀土硅酸盐熟料；将金属增韧型稀土硅酸盐熟料进行破碎、筛分，得到金属增韧型稀土硅酸盐粉末。该金属增韧型稀土硅酸盐粉末的制备方法的目的是解决稀土硅酸盐粉体制备成涂层后韧性较差且抗高温氧化性能不足的问题。
