EFFECT OF COATING CONTENT ON THE PROPERTIES OF A1(OH)3âY(OH)3/ZrB2 COMPOSITE PARTICLES
Zirconium diboride is widely applied to high-temperature materials, but it is easily oxidized at high temperature. To increase the oxidation resistance of zirconium diboride at high temperature, the A1(OH)3âY(OH)3 is coated on the ZrB2 surface to prepare A1(OH)3âY(OH)3/ZrB2 composite particles. In this paper, the effect of coating content on the properties of A1(OH)3âY(OH)3/ZrB2 composite particles is investigated. It is analyzed that the particle size and particle size distribution of A1(OH)3âY(OH)3/ZrB2 composite particles is increased with the coating content. The dispersion of ZrB2 particles is largely increased with the coating content of 0%â20%; the dispersion of ZrB2 particles is similar when the coating content is from 20% to 30%. The oxidation resistance ratio of the ZrB2 particles with 30% coating content is the best than that of other conditionsâit is about three times more than that of the original ZrB2 particles.
