Nanometre coating is the combination and comprehensive application of nanomaterial’s and surface engineering technology. It has been always regarded as a special application field by foreign militaries. Ships, aircraft and land equipment are facing extreme service conditions, including corrosion, wear, high temperature and other effects, as well as the resulting equipment operation failure and life expectancy decline. Nano-coating can solve the above problems more effectively. It is increasingly used in the military. Compared with other technologies, thermal spraying has the advantages of simple process, wide selection range of coating and substrate, wide variation range of coating thickness, high deposition efficiency and easy formation of composite coating. A new type of Nano-composite ceramic coating material was sprayed on the pipeline of fresh water cooler in submarine by spraying technology. The corrosion resistance of the material was verified by salt spray test. It is proved that this material technology can also be applied to equipment components in submarines to enhance their service life and improve overall performance.
