Titanium and titanium alloys have good physicochemical properties and are increasingly used in a wide range of industries, especially in aerospace. Titanium and titanium alloys are highly corrosion-resistant and generally difficult to corrode. However, in a certain environment, with the increase of service time, the surface of titanium alloy oxide layer is getting thicker and thicker

Gearboxes as bogies for railway vehicles is one of the precision and important components, it is of great practical significance to study the accurate, efficient and automated cleaning technology. However, the key parts of the gear box collector ring is very easy to corrosion, greatly affecting the gear box quality, stability and the service life of the entire transmission
