Alumina ceramic gears have excellent mechanical properties and resistance to high temperatures and corrosion, and can be applied to extreme working conditions that traditional metal gears cannot accommodate. However, its inherent high hardness and brittleness make it difficult to ensure a good surface during molding and manufacturing.

By proposing a novel alternating superimposed scanning strategy, processing errors were effectively reduced and surface integrity was enhanced. A univariate experimental system was used to optimize the key laser parameters (power, scanning speed, number of scans, and line spacing), and the optimal combination of parameters (7 W power, 220 mm/s scanning speed, 4 scans, and 0.005 mm line spacing) was finally determined to obtain a tooth surface with a surface roughness (Sa) of 1.091μm.
