Abstract Scope |
Improving the performance of the mold coatings is of great significance to extend the service life of the mold. This study examines the microstructure and hardness of coatings after different cryogenic holding times. The results show that the grain structure of the Ni-Co-Cr ternary alloy coatings remains unchanged after deep cryogenic treatment, no new phase is formed, and the grain size is significantly refined. In addition, the deep cryogenic treatment makes the particles on the surface of the coatings more compact and evenly distributed, so that its hardness is significantly increased. The study found that the hardness of the coatings increased by 12.8% after deep cryogenic treatment for 24 hours, respectively, compared with that before deep cryogenic treatment. At the same time, the effect of cryogenic treatment on the wear resistance of the coatings was explored. This study provides a new method for further improving the performance of mold coatings. |
