• 中文摘要： 吾人製作了四片含高鐵成份之鐵鈀合金以進行在高溫時其氧化情形之實驗。結果顯示所有的合金樣品在溫度範圍700C至850C之間的氧化皆遵守二次拋物線式的氧化增長定律。吾人並利用該定律算出形成各氧化層之活化能。同時也利用X光來分析各氧化層內所含之成份。20at％Pd的樣品被發現具有最佳之抗氧化能力。
• 英文摘要： Four Fe-rich Fe-Pd alloys samples were prepared for the high temperature oxidation tests. The re-sults show that all these samples follow the parabolic oxidation growth law in the temperature range be-tween 700C and 850C. We have used the power law to find out the activation energy for forming eachoxide scale. The X-ray analysis was carried out to analyze oxide scales formed during different stages ofoxidation at different temperatures. The 20-at% Pd sample is found to exhibit the best oxidation resistanceamong all samples.
