Surface treatment

Methods of surface treatment	Specific method	Main features
Sanding	Hand Sanding	Use sandpaper or abrasive cloth to manually grind away the uneven or rough surface
	Mechanical Sanding	Use mechanical equipment for efficient surface sanding to increase consistency
Polishing	Mechanical Polishing	Use polishing machinery and abrasives to polish the surface and increase the glossiness
	Chemical Polishing	Use chemical solutions to remove the roughness on the surface and obtain a smooth surface
Sandblasting	Sandblasting Rust Removal	Use high-pressure sand blasting to remove the surface oxide layer and rust
	Glass Bead Blasting	Use glass bead sandblasting agent to obtain a uniform and bright surface
Electroplating	Chrome Plating	Plate a layer of chromium on the surface to improve corrosion resistance and appearance
	Nickel Plating	Plate a layer of nickel on the surface to enhance hardness and wear resistance
	Gold Plating	Plate a layer of metal to provide a beautiful golden appearance.
Painting	Spray Painting	Use a spray gun to spray paint to provide uniform color and protection
	Powder Coating	Use static electricity to spray the powder on the surface to form a solid coating
Heat Treatment	Quenching	Improve the hardness and strength of the metal through rapid cooling
	Tempering	Reduce the quenching effect through heating and cooling, and increase the toughness
	Annealing	Heating and slow cooling to improve the machinability of the metal
Coating	Anti-Rust Coating	Add a coating with preservatives to increase the corrosion resistance of the material
	Anti-Scratch Coating	The scratch-resistant coating provides protection and appearance improvement
