Abstract
A method for forming a ceramic coating is provided. The method includes providing a slurry comprising a liquid and a plurality of feedstock particles disposed in the liquid, injecting the slurry into the flame of a thermal spray gun, and spraying the slurry on a surface of a substrate using the thermal spray gun to form the ceramic coating such that at least a part of the surface of the substrate is covered by the ceramic coating, wherein a thickness of the ceramic coating is in a range from about 10 nanometers to about 3 micrometers, and wherein a density of the ceramic coating is more than about 90 percent, and wherein the ceramic coating is a continuous coating.
Claims14
A method for forming a ceramic coating comprising:
- providing a slurry comprising a liquid and a plurality of feedstock particles disposed in the liquid;
- injecting the slurry into the flame of a thermal spray gun;
- and
- spraying the slurry on a surface of a substrate using the thermal spray gun to form the ceramic coating such that at least a part of the surface of the substrate is covered by the ceramic coating, wherein a thickness of the ceramic coating is in a range from about 10 nanometers to about 3 micrometers, and wherein a density of the ceramic coating is more than about 90 percent, and wherein the ceramic coating is a continuous coating.
A method for forming a ceramic coating comprising:
- providing a slurry comprising a liquid and a feedstock, wherein the feedstock comprises indium tin oxide (ITO) particles, wherein the size of the ITO particles has a d90 less than about 3 microns;
- feeding the slurry in a thermal spray gun device;
- and
- spraying the slurry on a surface of a substrate to form the optically transparent ceramic coating.
