In this study, we investigated the relationship between the structural changes and wetting properties of porcelain enamel doped with CoO. Glass with the composition 45SiO 2 15B 2 O 5 25NaO15CaO was doped with different CoO concentrations. The wetting properties were characterized by high-temperature microscopy and the structural changes were observed by scanning electron microscopy, X-ray photoelectron spectroscopy, electron probe microanalysis, Fourier transform infrared spectroscopy, and energy dispersive X-ray spectroscopy. CoO addition increased the number of non-bridging oxygen atoms in the glass system, as well as the wetting ability. The addition of CoO to the porcelain enamel not only increased adherence, but also decreased the sintering temperature.

State-of-the-art abrasion resistance of glass ceramic coatings (GCCs) is set by dense, low closed porosity, defect-and micro-stress-free microstructure since GCCs have low fracture toughness. Titanium diboride (TiB 2 ) is a ceramic material with relatively high strength and durability as characterized by the high melting point, hardness, and wear resistance. In this study, the effect of mill additive TiB 2 hard ceramic particles (HCP) on GCCs was investigated. The precursor glass ceramic system of SiO 2 -Na 2 O-B 2 O 3 -CaO-Fe 2 O 3 was selected. The wear resistance of the GCCs was tested simultaneously by Taber Abraser and by a tribometer. B 2 O 3 , which is formed by the oxidation of TiB 2 , fills the pores and the microcracks on the surface, thus reducing the stress areas and increasing the wear resistance. Increasing the TiB 2 HCP addition yielded a decrease in mass loss of about 81%, wear rate of about 82% and increase in the coefficient of friction of 15%.
