摘要: | 本研究針對汽車防傾桿(材質為SUP9彈簧鋼),建立其最佳熱處理製程,並探討不同熱處理參數對於材質之影響。在實驗方法上,首先分析並評估現階段所採用之熱加工及熱處理製程所得到之防傾桿之金相組織及硬度,然後根據評估結果,探討不同熱處理參數對於防傾桿材質之影響,以建立最佳熱處理條件。最後,再根據本研究所建立之最佳熱處理製程條件,進行防傾桿之耐久性測試,以驗證所建立之最佳熱處理製程之可行性及可靠度。本研究之目的在於建立防傾桿之最佳熱處理製程,以獲致優良硬度及耐久性之防傾桿,以期在實際量產時提升防傾桿之品質,而研究結果亦可提供實際熱處理製程參數設定之參考。
本研究所獲致之最佳熱處理條件為如下: (a) 針對Φ17 mm之桿徑而言,最低淬火溫度為800℃,故建議之加熱溫度必須要在1040℃以上。若硬度值需400Hv以上,則回火溫度必須要在450℃以下。若硬度值需350Hv以上,則回火溫度必須要在500℃以下。 (b) 針對Φ22 mm之桿徑而言,最低淬火溫度為800℃,故建議之加熱溫度必須要在1015℃以上。若硬度值需400Hv以上,則回火溫度必須要在450℃以下。若硬度值需350Hv以上,則回火溫度必須要在500℃以下。 (c) 針對Φ30 mm之桿徑而言,最低淬火溫度為850℃,故建議之加熱溫度必須要在1055℃以上。若硬度值需400Hv以上,則回火溫度必須要在420℃以下。若硬度值需350Hv以上,則回火溫度必須要在480℃以下。 由防傾桿耐久性試驗結果顯示,本研究所建立之熱處理製程條件,可有效提高防傾桿之耐久性。 This research intends to establish the best heat treatment process of the anti-roll bar. Its material is the SUP9 spring steels. The experimental technique is to analyze the present microstructure and degree of hardness of the anti-roll bar first. According to the analyzed consequence and the influence of different heat treatment parameters regarding the anti-roll bar, this research try to establish the best heat treatment process of the anti-roll bar. Finally, according to the results of durability test, the feasibility and dependability of the best heat treatment process conditions are conformed. The goal of this research lies in the establishment of the best heat treatment process conditions, obtaining the fine degree of hardness and the durability of the anti-roll bar. The best heat treatment conditions of this research are as follows: (a) For the anti-roll bar of diameter 17 mm, the lowest quenching temperature is 800 ℃, and therefore heating temperature must be above 1040 ℃. If the degree of hardness value needs above 400Hv, then the tempering temperature must be below 450 ℃. If the degree of hardness value needs above 350Hv, then the tempering temperature must be below 500 ℃. (b) For the anti-roll bar of diameter 22 mm, the lowest quenching temperature is 800 ℃, and therefore heating temperature must be above 1015 ℃. If the degree of hardness value needs above 400Hv, then the tempering temperature must be below 450 ℃. If the degree of hardness value needs above 350Hv, then the tempering temperature must be below 500 ℃. (c) For the anti-roll bar of diameter 30 mm, the lowest quenching temperature is 850 ℃, and therefore heating temperature must be above 1055 ℃. If the degree of hardness value needs above 400Hv, then the tempering temperature must be below 420 ℃. If the degree of hardness value needs above 350Hv, then the tempering temperature must be below 480 ℃. |
