| 为了解决冷辊轧模具寿命短、人工修复周期长、修复一致性差等问题，提高了模具耐磨性，延长模具使用寿命，在辊轧模
具表面涂敷了PVD强化涂层。采用真空阴极多弧离子镀技术，在不同材质模具钢表面制备AlCrN多元纳米硬质涂层。试验样品
基材选用Cr8W1Mo2V2SiNb、W6、Cr12MoVCo及V-4E工具钢作为样品基体，采用2种工艺制备硬质PVD涂层，V-4E基材AlCrN涂
层的晶粒尺寸最小，沉积的AlCrN涂层结构更致密。V4E+CrAlSiN强化体系获得最优的综合测试性能。验证结果表明：涂敷PVD
强化涂层可使模具寿命提高20倍以上。 |

| In order to solve the problems of low life，long manual repair period and poor repair consistency，the wear resistance of the
die was improved and the service life of the die was prolonged. PVD coating was applied on the surface of the rolling die. Multi element na?
no hard coatings of AlCrN were prepared on the surface of die steel with different materials by vacuum cathode multi-arc ion plating tech?
nology. Cr8W1Mo2V2SiNb、W6、Cr12MoVCo and V-4E tool steels were selected as the base materials. The grain size of AlCrN coating on
V-4E substrate was the smallest，and the structure of deposited AlCrN coating was more compact. V4E+CrAlSiN strengthening system ob?
tained the best comprehensive test performance. The results show that the service life of the die can be increased by more than 20 times
with PVD strengthening coating. |
