Zusammenfassung:	Disclosed are a gear product having an enhance deposition surface and a deposition system for manufacturing the gear product. The gear product having a reinforced deposition surface according to the present disclosure includes: teeth in which valleys and crests are successively formed along an outer or inner circumference of a cylindrical body having a central rotation shaft; and a reinforced deposition layer, which is formed by radiating a laser beam in a coaxial nozzle system to be directed to the teeth and injecting powdered materials to be in contact with a radiation axis of the laser beam around the radiated laser beam such that the powdered materialsaremelted and integrated with a surface of the teeth. According to the present disclosure, a reinforced corrosion-resistant and wear-resistant deposition layer formed on a gear product is formed through a coaxial nozzle system in which powdered materials, which are injected so as to be in contact with the radiation axis of a laser beam radiated towards teeth around the radiated laser beam, is melted by the laser beam so as to be deposited on the surface of the teeth. Thus, it is possible to freely and finely control the laser beam power, the rotational speed of the gear, and the type and the injection amount of powdered materials according to the shape and size of the crests and valleys (teeth), and the physical properties of the raw material constituting the gear product, so that a deposition layer, optimized to the teeth having various shapes and physical properties, can be uniformly and precisely formed.
