dc.description.abstract | 本研究將SKD61、SKH51、SKD11、SUS420J2等各種工具鋼施以滲氮處理、氧化處理及滲氮氧化複合處理後,置於720℃的鋁合金熔液中實施熔蝕試驗,由試片單位面積的重量減少量評估上述各種表面改質處理對鋼料耐鋁液熔蝕效果的影響。並配合顯微組織的觀察、化學成分的分析及X-ray繞射實驗,探討鋼料在鋁液中的熔蝕反應機構。實驗結果顯示,鋼料經滲氮或氧化處理後對於抵抗鋁液的熔蝕能力都有顯著增加,尤其是滲氮氧化複合處理的效果最好,鋼料經滲氮氧化複合處理後,在相同條件下的熔蝕量不到原材的十分之一。鋼料在鋁液中的蝕反應主要是由於鋼料中的鐵元素(Fe)擴散到鋁液中,和鋁液中的鋁(Al)、矽(Si)等元素形成Fe-Al-Si金屬間化合物。由於滲氮層及氧化層有阻礙鐵元素(Fe)擴散到鋁液中的效果,故能降低鋼料在鋁液中的熔蝕速率。 | zh_TW |
dc.description.abstract | Tool steels, such as SKD61, SKH51, SKD11 and SUS420J2, after nitriding, oxidation, or nitride-oxidation compound treatment are dipped in liquid aluminum at 720℃ for erosion tests. Effects of above surface modification treatments on the resistance of steels to erosion in liquid aluminum are evaluated by weight loss per unit surface area. Furthermore, erosion mechanism of steels in liquid aluminum is investigated through microstructure observation, chemical composition analysis and X-ray diffraction test. The experimental results show that the resistance of steels to erosion in liquid aluminum can be significantly increased either by nitriding or oxidation treatment. Moreover, the effect of resisting erosion for nitride-oxidation compound treatment in especially excellent. The weight loss of steel sample after the compound treatment is smaller than one tenth of the plain steel at the same erosion test conditions. The dominant process of erosion mechanism in that the iron atom of steels diffuses to liquid aluminum and formed Fe-Al-Si intermetallic compounds with the element of aluminum and silicon in the liquid. Either the nitrided layer or oxidation layer of steels is a barrier for iron atom to diffuse to liquid aluminum that results in the reduction of erosion rate of steels. | en |
