壓鑄模具在熔融鋅合金液高速度射入及內部急速冷卻的生產過程中,因受到熔融鋅合金液反覆不斷的衝擊模具表面,造成模具長期處於高溫冷卻循環狀態下,導致易產生軟銲、沖蝕與熱疲勞等模具的缺陷,而影響壓鑄件之良品率與生產成本浪費。為了改善壓鑄模具的缺陷,通常對模具表面施加表面處理之方式,以降低模具缺陷的產生,而增加模具壽命。
本研究利用表面處理方式之物理蒸鍍處理和滲氮處理,進行實際壓鑄探討表面處理對鋅壓鑄模具材料H13熱作模具鋼之影響,欲暸解何種表面處理有較佳抵抗鋅軟銲、熱疲勞之裂痕與沖蝕等能力,以提升模具壽命。
研究結果顯示經過壓鑄循環1000、3000與5000次之後,物理蒸鍍表面處理之H13熱作模具鋼,有較佳抵抗鋅軟銲、熱疲勞與沖蝕之能力,因經過多次壓鑄循環之後,物理蒸鍍鍍層仍然存在,表面產生鋅軟銲較少,無熱疲勞裂痕產生。滲氮處理雖然表面硬度較高,但抵抗鋅軟銲之能力沒有物理蒸鍍處理佳,並且滲氮層有明顯之改變。若H13熱作模具鋼未做任何表面處理,其鋅軟銲量會以倍數成長,並且產生熱疲勞之裂痕與沖蝕現象。
Die Casting in which molten zinc alloy is injected into a cooled metallic mold or die under high velocity and high pressure of production, the die surface is affect to repeatedly continuous impact by the molten zinc alloy, cause the die been placed heat cooling circulation appearance over a long period of time under. Die failure is mostly caused by soldering, washout, thermal cracks, the influence castings the fine goods rate and production cost of the piece the waste, for improving the die failure, usually exert the way of the surface treatment to the die surface, the creation of the since low die failure and increase the die life.
This research makes use PVD and Nitriding treatment, study surface treatment effects of PVD and Nitriding treatment on H13 hot work die steel for zinc die casting, wanting the solution what surface processing has the better holdout zinc soldering, thermal cracks and washout , to promote the die steel life.
The results show that die casting cycle 1000, 3000 and 5000 times after, the PVD coating of H13 hot work die steel has best resistance of zinc soldering, thermal cracks and washout. Although surface of hardness is higher on the nitriding treatment, but not has better resistance on PVD, and nitriding coating is obvious of change. H13 did not do any surface treatment, the zinc soldering will grow up with the multiple, and produce the thermal cracks and washout.
