摘要

本研究採用旋轉式 Ball on Disk 摩擦試驗機暨量測系統，在摩擦過程中，動態量測摩擦係數及表面磁場之變化，以研究不同熱處理方式對冷模工具鋼磨潤性質的影響。在摩擦試驗後，利用電子顯微鏡(SEM)觀察磨耗過程所產生之磨耗顆粒(Wear particle)，並量測磨耗損失量(Wear loss)來研究不同熱處理方式影響冷模工具鋼磨潤性質的影響。Ball使用碳化鎢球，Disk則分別使用日本大同公司DC53模具鋼與日本日立公司SLD模具鋼，並變化不同淬火溫度、回火溫度、深冷處理溫度與氮化處理等熱處理條件，並規劃以垂直負荷及線速度為實驗操作參數。

根據實驗結果可知動態監控模具鋼表面磨耗機制的方法可提供業界依據不同需求而選擇適當之熱處理方式，以作為模具鋼產業進一步發展之參考。

The experiments were conducted on a ball/disk friction tester with a measuring system to dynamically investigate the tribological behaviors of the tool steels with different heat treatments in dry severe wear process. The friction coefficient and the surface magnetization were dynamically measured during the friction process. Moreover, the wear loss of the specimens and the SEM observations of the wear particles were conducted after the friction test. The ball was made of WC. Moreover, DC53 and SLD were selected as the disk. The heat treatments included Quenching, Tempering, Deep-Cryogenic-Treatment and Nitride. Normal load and sliding speed were selected as the experimental parameters.
According to the experimental results, the method of dynamic monitoring the tribological properties of the tool steel was useful in the choice of various heat treatments for the industry. This will be very helpful for the improvements of tool steel manufacturing.
