Features of laser cladding for corrosion protection

Thread Content

Laser corrosion protection: Depending on the type of corrosive agent and the operating conditions of the component, coating materials that can form a dense passivation film are selected accordingly, to develop specialized corrosion-resistant laser-coated layers for customers. 　　1. Special laser-coated layer resistant to H2S corrosion: Coating the surface of carbon steel or alloy steel with materials resistant to H2S corrosion can enhance its corrosion resistance when used in repairs, such as in screw compressors in the petrochemical industry ； Application in manufacturing can reduce production costs, such as in drilling tubing. 　　2. Laser-specific coating resistant to concentrated H2SO4 corrosion: In the electro-galvanizing production lines of the metallurgy industry, the corrosion-resistant layer on the surface of conductive rollers becomes severely damaged after long-term use, rendering them unusable. By applying our company’s laser cladding technology, the functional properties of these conductive rollers can be restored. 　　3. Laser-specific coating resistant to HF corrosion: In special operating conditions or environments, such as centrifugal gas compressors or industrial steam turbines in the petrochemical industry, which are subject to HF corrosion, repair using our company’s laser cladding technology **improves the corrosion resistance of the component surfaces. 　　4. Laser-specific coating resistant to seawater chloride corrosion: Offshore drilling platforms are severely damaged by seawater corrosion, and parts treated by spraying or electroplating cannot be used for long periods of time. The corrosion-resistant material developed by our company offers more than ten times the resistance to corrosion compared to traditional stainless steel. 　　5. Special laser coating resistant to water vapor corrosion: In the metallurgical industry, the rolling mill frames are exposed to a water vapor environment during operation, which leads to severe corrosion. After being repaired using our company’s laser cladding technology, their corrosion resistance is more than 200 times that of the original material. 　　6. Laser-specific coating resistant to molten zinc corrosion: In the hot-dip galvanizing production lines of the metallurgical industry, the submerged rolls and stabilizing rolls are exposed to liquid zinc at high temperatures, resulting in severe corrosion of their shaft sleeves. To address this issue, shaft sleeves are manufactured from materials resistant to molten zinc corrosion, which increases costs. By coating a material resistant to molten zinc corrosion on the surface of stainless steel, it is possible to reduce costs while maintaining the same service life
