| 中文摘要 | 本文討論表面硬度對 DC53 工具鋼濕砂沖蝕的影響,DC53 工具鋼經鹽浴滲碳 氮化(NC)、低溫電漿氮化(PN)和TiN 鍍膜處理以形成不同表面硬度後作水/碳化矽 砂混合漿料的沖蝕測試。濕砂沖蝕時間為5 小時,沖蝕角度為15° 至 90°,沖蝕 速度為17.5m/s。測試結果將和未處理試片作比較與討論。 結果顯示,增加試片表面硬度可降低材料的累積重量損失,材料重量損失的 減少量並和其表面硬度密切相關。經1 小時沖蝕測試後,未處理和鹽浴滲碳氮化 兩種試片的最大沖蝕率角度為30°,電漿氮化和TiN 鍍膜試片的最大沖蝕率角度分 別為45° 與90°。和未處理試片相較,三種表面處理對DC53 工具鋼抗濕砂沖蝕能 力的提升順序為NC PN TiN 鍍膜,恰和其表面硬度大小趨勢相同。在1 至5 小時測試期間,鹽浴滲碳氮化、電漿氮化和TiN 鍍膜三種處理降低DC53 工具鋼 最大沖蝕率的倍數分別可達1.61.3、2.51.7 與603.6。 |
| 英文摘要 | Different surface treatments are conducted on newly developed cold work tool steel, of commercial name DC53 (Daido Steel, Japan), to produce different surface hardness. Four kinds of sample conditions are studied in the slurry composed of water and silica carbide particles: as-received, liquid nitrocarburizing (NC), low temperature plasma nitriding (PN) and TiN coating deposition. The slurry erosion tests are performed during 5 h in a water jet device with impinged angles ranging from 15° to 90° and an impinged velocity of 17.5 m/s. In this paper, the erosion behaviors obtained on the surface treated samples are compared with those of the as-received sample. Test results indicate that increasing in the hardness shows lower weight losses. The comparable weight loss of the samples is supported by their comparable surface hardness. After one hour testing, the maximum erosion rate for the as-received condition and NC samples is at an impinged angle of around 30° while the maximum erosion rate for the PN and TiN coated samples is at impinged angles of 45° and 90°, respectively. As compared with the as-received condition, the effect of the surface treatment on the improvement of the erosion resistance of the DC 53 tool steel increases in the order NC PN TiN coating. With the test durations between one and five hours, the liquid nitrocarburizing, the low temperature plasma nitriding and the TiN coating deposition reduce the maximum erosion rate of the DC 53 tool steel by 1.61.3, 2.51.7 and 603.6 times, respectively. |
