Effects of Additives on Performance of Sintering and Antioxidation of Zr(Ca)-Al-O-N Composites
Abstract:
Influencing effects of additives CaF2, ZrB2 and MoSi2 on sintering performance and oxidation resistance of Zr-Al-O-N composites were investigated. The results showed that additives CaF2, ZrB2 and MoSi2 were beneficial to improve sintering density of Zr(Ca)-Al-O-N composites, and additives CaF2 and ZrB2 were beneficial to improve obviously bending strength of samples Zr(Ca)-Al-O-N composites and MoSi2 was contrary. After additives CaF2, ZrB2 and MoSi2 were introduced to Zr(Ca)-Al-O-N composites, oxidation resistance of Zr(Ca)-Al-O-N composites was improved, and relative superior or inferior of influence ranking of additives was MoSi2, CaF2, and ZrB2.
