A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is the most important component of engineering machinery and the most prone to problems. In particular, scratches on the inner surface of the cylinder are more common.

The surface coating prepared by laser cladding is metallurgically bonded to the base material, and the bonding is very reliable and will not cause peeling problems;

Laser cladding has no limit on additive thickness. In addition to preparing surface coatings, it can also perform additive repairs for workpieces with larger wear dimensions;
