Hardness and wear resistance of arc spraying coatings

Jiang Jianmin, Fu Binyou, He Dingyong, and Dong Na verified that the relationship between the wear resistance of the coating and the hardness of the coating is not much, and the main factor is the phase distribution in the coating . In addition, the mechanism of arc spraying eF-based coatings was also studied, and it was concluded that the coating has good resistance when the various hard phases embedded in the metal matrix are uniformly distributed in the collective and have good compatibility with the matrix. Abrasive.

The experiment mainly uses the arc spraying method to prepare four different iron-based coatings, and then uses the HXD-100 microHardness Tester to test the microhardness of the sample, and uses the TH32O full Rockwell Hardness Tester to measure the Rockwell hardness of the sample surface. Finally, the wear resistance test was carried out by using the MLS-225 wet rubber wheel abrasive wear Tester.
