A boron carbide coating was applied to diamond particles by heating the particles in a powder mixture consisting of H3BO3, B and Mg. The composition, bond state and coverage fraction of the boron carbide coating on the diamond particles were investigated. The boron carbide coating prefers to grow on the diamond (100) surface than on the diamond (111) surface. A stoichiometric B4C coating comple...
The hydrophobicity of microtextured diamond surfaces was investigated. Pillarlike structures were fabricated in both nanocrystalline diamond and microcrystalline diamond. By changing the surface termination of the textured diamond surface, we could switch between superhydrophobic surfaces and hydrophilic surfaces. Examined terminations were hydrogen, fluorine, and oxygen. To evaluate the wettin...
Methods: Forty disc-shaped specimens were fabricated with a feldspathic porcelain (Super Porcelain EX3), glazed, and randomly divided into 4 experimental groups and 1 control group (n=8/group). For the experimental groups, the glazed layer was ground with a diamond rotary instrument, and the surface was polished with: rubber points (Edenta), steel finishing burs (Meisinger), silicon rubber poin...
