Damage behavior in ceramic plasma-coated and uncoated glass with steel-ball impact
A ceramic plasma-coating method that reduces damage from particle impact in a ceramic material is suggested. A steel-ball impact test was performed to investigate and compare the damage behavior of uncoated and ceramic-coated glass. Cone and lateral crack lengths were compared and damage volume analyzed and compared for different steel-ball diameters and types of coating materials, Al2O3-TiO2, Al2O3, and Cr2O3. Damage resistance of the coating and Al2O3-TiO2 was found to be best because of its mechanical properties and microstructure.
