本文研究了ＰＣＶＤ（等离子化学气相沉积）模具强化技术。试验结果表明，ＰＣＶＤ复合渗镀技术可以显著提高热锻模的使用寿命，用于热挤压模的效果显著优于气体氮化处理的效果，用于中低温回火的冷作模具，可显著提高模具的使用寿命，改善模具的韧性．ＰＣＶＤ法表面强化可显著提高压铸模具钢的热疲劳抗力，极大地改善其耐铝液腐蚀性能。ＰＣＶＤ法表面强化应用于压铸模也会有良好效果。
This paper studies PCVD (Plasma Chemical Vapor Deposition) mold strengthening technology. The results show that the PCVD composite infiltration technology can significantly improve the service life of the hot forging die, the effect of hot extrusion die is significantly better than the effect of gas nitriding, for low temperature tempering cold die, can be significant Improve the service life of the mold and improve the toughness of the mold. PCVD surface strengthening can significantly improve the thermal fatigue resistance of die-casting mold steel, which greatly improves its resistance to molten aluminum corrosion. PCVD surface hardening applied to the die-casting mold will have good results.
