Development and application introduction of industrial electron accelerator and surface treatment implementation with an ion beam made in China

Abstract

The S-band electron linear accelerator developed for nondestructive testing is primarily used to inspect pressure vessels, petrochemical parts, and other industrial components. The X-band electron linear accelerator has been developed in RIAMB, owing to its advantageous flexibility and light weight and can be used for on-site testing. The integral solution of the irradiation electron linear accelerator system provided by RIAMB includes an accelerator, transmission line, production management system, automatic storage and retrieval system, and workshop. The electrocurtain accelerator is currently being developed in RIAMB. At present, it includes two models, with maximum accelerating voltages of 200 kV and 150 kV, respectively. The ion beam surface processing technology includes ion implantation surface modifications, magnetic filtration multi-arc ion coatings, and ion beam assisted deposition coatings. It forms a corrosion-resistant, friction-resistant, anti-icing, and friction-reducing film on the surface of parts such as bearings and pitot tubes, which are primarily used in the aerospace field.
