真空熱壓燒結溫度對Cr_(50)Cu_(50)奈米合金靶材其微結構與電性之影響

Effect of Vacuum Hot-pressed Sintering Temperature on the Microstructure and Electrical Properties of Nanostructured Cr_(50)Cu_(50) Alloy Targets

摘要


鉻銅合金具有良好的抗電弧沖蝕特性、優越的電導性與熱導性,因此廣泛應用於電子接觸材料(Electrical contact material),近年來更被應用於銅鉻氧半導體薄膜之濺鍍靶材。而真空熱壓燒結法(Hot-pressed sintering)是一種複合型的燒結成形方法,結合了真空燒結與加壓成形兩個部分,其製程是透過一個石墨模,直接將壓力傳輸至粉末,並同時進行壓製和燒結材料。本研究運用各種不同的熱壓燒結溫度(950、1000、1050和1100℃),壓力維持在12MPa且持溫持壓1小時下,對Cr50Cu50之奈米鉻銅合金靶材進行真空熱壓燒結,並以孔隙率、相對密度、XRD分析以及金相組織觀察與其電性來進行一連串的討論,並且評估其優劣及應用價值。實驗結果顯示,Cr_(50)Cu_(50)奈米鉻銅合金靶材在12MPa,1小時下的最佳熱壓燒結溫度為1050℃,其相對密度可達96.09%,視孔隙率降至0.12%,且具有較佳之電性(電阻率為5.89×10^(-6)Ω.cm),因此更適用於鉻銅奈米合金靶材之製造。

Vacuum hot-pressed sintering is a complex method that combines the sintering and pressing processes. In this process, the material is directly pressed and sintered through a graphite mold to transmit the pressure onto the powders. This study conducted the hot-pressed sintering process at various temperatures (950, 1000, 1050 and 1100℃) to determine the effect of sintering temperature on the properties of hot-pressed sintering nanostructured Cr_(50)Cu_(50) alloy targets. For each of these experiments we determined the porosity, relative density and electrical properties. Experimental results showed that the optimal condition of the hot-pressed sintering of nanostructured Cr_(50)Cu_(50) alloy targets was 1050℃ at12 MPa for 1 h. The relative density was 96.09% and the apparent porosity was 0.12%. The optimal electrical resistivity was 5.89×10^(-6) Ω.cm, which was suitable for the fabrication of nanostructured Cr_(50)Cu_(50) alloy targets.
