Abstract

PURPOSE:To improve the grade of crystallized glass by coating the glass with a ceramic having a linear expansion coefficient different from that of the glass. CONSTITUTION:The material to be thermally sprayed is selected from the crystallized glasses having <=20X10<-7>/ deg.C linear expansion coefficient such as LiO2- Al2O3-SiO2 (TiO2 as the nucleus forming component), Li2O-Al2O3-SiO2 (P2O5 as the nucleus forming component), MgO-Al2O3-SiO2 (TiO2 and P2O5 as the nucleus forming components) and CaO-MgO3-SiO2 (a fluoride as the nucleus forming component). A mixture of a ceramic having a linear expansion coefficient different from that of the crystallized glass by <=50X10<-7>/ deg.C such as beta- eucriptite, beta-spodumene and silica glass, a low-expansion flux such as TiO2- SiO2-based glass and Cu2O-Al2O3-SiO2-based glass, metal oxides, silicates and a pigment is thermally sprayed on the glass by the gas spraying method using a gas heat source such as O2-acethylene and O2-propane or the electric spraying method using a heat source such as arc, plasma and high-frequency induction heating to obtain a coating layer having <=100mum thickness.

[Problem to be solved by the invention] In the conventional method, it is difficult to provide a high-quality coating layer that is multi-colored and glossy due to the influence of the thermal expansion coefficient of the crystallized glass that is the material to be coated. It wasn't easy. In particular, when the coefficient of linear expansion of crystallized glass is relatively small, 20×10-7/"C or less, it is necessary to increase the firing temperature to obtain gloss. However, this causes deformation of the coated material itself. It has been difficult to obtain a high-quality coating layer due to softening and changes in physical properties.
