Due to the tendency to return to its natural oxidized state, metalworks undergo corrosion due to the continuous reactions with the environment where there is presence of oxygen and moisture, and this leads to the formation of rust. When corrosion occurs, metal items lose their metal properties and strength, and become vulnerable to damage and destruction even with little physical impact. They will also start to lose its original appearance, as rust begins to cover the surface.

X-ray can be used on a metalwork to determine its internal structure, type of damage that has occurred, and the extent of the corrosion.

If foreign matter or corrosion products have adhered to the surface, then small tools for preservation treatment are used to physically remove such matter, or chemicals are used to selectively remove the corrosion products.

Reinforcement and Bonding Treatments

Picture 1 Surface reinforcement treatment

Reinforcement treatment is performed to reinforce the internal material, which has weakened due to corrosion or cracks, using synthetic resin. In this process, a protective film is formed on the surface and internal area to block direct contact with the external factors that cause corrosion.

Damaged fragments are pieced together using an adhesive, and if there are missing parts, which make the item structurally weak, a restorative agent is used to restore the item to its original state.
