Abstract
Erosion behavior of Supercritical Nano-Plating (SNP) material was studied, especially focused on the dependence of the tilting angle between plate surface and blasting direction. Tilting assembly was installed in the commercially available blasting machine which is used for drawing graphical pattern on glass tableware by powder blasting. Damaged surface and cross-section were observed with optical microscope and scanning electron microscope. Normal and tangential force measurement unit was introduced for the measurement during erosion tests. Superiority of SNP was confirmed as thinner controllable plating of higher hardness with excellent integrity against powder-blasting erosion, compared with conventional method. Tangential force during erosion test was not measured successfully but measured normal force showed good agreement with theoretical expectation. It would be suggested that better understanding of the damage process during powder-mixed blasting needs the detailed research on powder impact behavior itself.
