Abstract:In the processing of hard and brittle materials such as silicon nitride (ππ 3 π 4 ), machining is often accompanied by numerous shortcomings which lead to poor processing efficiency. In order to enhance the grinding efficiency of silicon nitride ceramics, the material's strength is weakened through a 355 nm nanosecond pulsed laser for generating microscale textural patterns on ceramic surfaces. This paper investigates the influence of overlap rate on the material surface and the scratching characteristics o… Show more
