The Preparation and Properties Study of the Zirconia Dispersion-Strengthened Platinum Materials

摘要：

　　The zirconia dispersion-strengthened platinum thermocouple materials were successfully fabricated by powder metallurgic method.It was studied the zirconia grains influences on platinum materials.The results of the study show that its density is 21.4g/cm3 and its relative density is 99.8%.Its tensile strength obvious overtop pure platinum, the maximum tensile strength is 930MPa.The cures of tensile strength with the processing rate improved of the materials obey a analogy-linear law.The resistance ratio (R100/R0) ≥ 1.3922, and thermal electromotive force of Pt matched PtRhl0 meet I measuring accuracy grade relative to GB/T1598-2010 stander.
