| 摘 要： | 研究了稀土氧化物对高硬度堆敷金属中夹杂物的影响,结果表明:稀土氧化物能够降低夹杂物的尺寸,增加其弥散度,但对其形状系数没有影响。通过异质核心的作用,能够细化堆敷金属中的一次结晶组织。稀土氧化物可以在保持堆敷金属高硬度的条件下,使堆焊层韧性性能提高了37％。

| Abstract: | The effect of rare earth oxide in high - hardness surfacing on inclusion is studied in this paper. The result shows that dimension of inclusion can be reduced and its dispersion can be increased, but its shape factor cannot be changed by rare earth oxide. The first crystallized microstructure can be fined though the effect of rare earth oxide on heterogeneity nucle-us. Toughness of surfacing can be improved 37 percent on the condition of keeping its high hardness at the same time by adding rare earth oxide in it. |
