Wear Characteristics of the Sprayed Coatings With Amorphous Material Available to Purchase

Characteristics of the sprayed amorphous material’s coating have been investigated in order to improve the life of liners used in a blasting system. The amorphous materials of interest were commercial Fe-Cr-B alloys and the processes employed were arc spray and HVOF spray. Erosion wear property of the coatings were evaluated using a steel grit blasting machine and actual blasting system. The coating produced by HVOF spraying method showed a very dense structure so that porosity content of the coating was less than 1% and split was not formed. Due to these features with its high hardness, the wear resistance of the HVOF sprayed coating was superior to that of the arc sprayed coating. Microstructural characteristic of the amorphous material’s coating were analyzed using SEM, EDX and XRD.
