Effect of CO₂ laser power intensity on the surface morphology and friction behavior of alumina ceramic brackets

Abstract

Different CO laser power intensities significantly affect frictional resistances of SS-wires in Al O ceramic brackets.

Tailoring an Interface Microstructure for High-Performance Reversible Protonic Ceramic Electrochemical Cells via Soft Lithography

“…As a resolving route toward the application of a micropatterned interface for high-performance ceramic cells, imprinting methods that have a great benefit in manufacturing simplicity and mass productivity have received research attention as a new generation of micropatterning technology. Unlike previous approaches such as plasma spraying treatment , and laser-machining, − imprinting methods modify the cell structure before the high-temperature sintering process, resulting in wider freedom to choose pattern geometries and better processibility from patterning in a green state. Several imprinting methods have been attempted to achieve unique advantages of these methods with great potential; − however, researchers have failed to realize their methods in practically operatable ceramic fuel cells until recently, indicating that traditional imprinting methods need to be properly tuned to pattern a dense and thin ceramic electrolyte.…”
