Characterization Of Polyester- Cu-Zm-Al203 Nanocomposite As Coating Layer For Steel Welding

Polymer coatings are thin layers of corrosion protection that can be applied to welded steel. The development of a polyester- based coating with metal fillers could assist homogeneous dispersion on weld surfaces. This study develops and characterizes the polyester- Cu- Zn- Al203 coating and its corrosion performance on welded steel. Cu- Zn- Al03 reinforcement was first milled at 40 h at 300 rpm, mixed with polyester to produce a film, and coated on welded steel. The results showed that milled consists of nanostructure and various particle distributions.
The amount of filler in the polyester- Cu- Zn- Al20з composite film was maximum at 1.0wt%. The corrosion rate monitored from 5 to 20 days shows a consistent trend with 2.0wt% showing the highest corrosion resistance which is caused by the protective surface film. The corrosion behavior of welded steel depends very much on the filler content. The corrosion behavior of welded steel is significantly influenced by the filler content. It is essential to carefully analyze a filler material' sl use and any potential effects it may have on the steel's corrosion behavior since the composition of a filler material has the potential to either increase or diminish the welded joint's corrosion resistance. The endurance and performance of welded steel can be increased by using the right filler material and welding procedures to provide long-term corrosion resistance.
