Abstract
A plasma spray process for structuring self-cleaning glass surfaces and self-cleaning glass surfaces formed according to the process. Molten or heat softened particles of inorganic material are plasma spray deposited onto the surface of a substrate to create a micro-rough surface. If desired, a hydrophobic top coating layer can optionally be applied to the micro-rough surface. The micro-structured surface formed according to the invention is durable and self-cleaning.
