The current situation of laser cladding in marine engineering

As the energy crisis worsens, many countries are paying more and more attention to marine development and research. How to avoid the corrosion and protection problem of the metal materials under the sea has become a heated topic in marine engineering research.

In marine environment, increasing the corrosion resistance is an effective way to protect the metal. Among a dozen of surface treatment techniques, laser cladding machine has attracted many researchers’ attention. 

Laser cladding uses high energy laser beam on the surface of the metal. Through rapid fusing and cooling, a layer of cladded material that has special physical, chemical or mechanical properties  is formed on the base material surface and together they become a new compound material. This kind of compound material can not only bring out the best of the base material and the cladded material but also compensate their disadvantages, which can greatly improve the corrosion resistance of metal materials under marine environment and extend its service life. 

Take stainless steel as an example. Stainless steel is often used in the pump, valve, anchorage bar, etc. In marine projects. It has pretty low corrosion rate in the marine environment. The major corrosion form is partial corrosion like pitting corrosion or crevice corrosion. Ordinary stainless steel can not be used widely in marine engineering because of its poor pitting corrosion resistance properties. But with laser cladding technique, ordinary stainless steel can be put on high performance alloy steel so that it become has better pitting corrosion resistance. 

To sum up, laser cladding is very ideal for surface treatment on components that are prone to be corrosive or abrasive in marine environment. 

Laser cladding machine is often equipped with fiber laser as the laser source. To prevent the fiber laser source from overheating, effective cooling must be provided. S&A Teyu is one of the renowned water chiller manufacturers in China and provides industrial water chillers special for fiber lasers - CWFL series. CWFL series industrial water chillers can meet the cooling demand for fiber lasers from 0.5KW to 20KW.
