• Plating

  Applying a thin layer of metal (like gold, silver, or nickel) to the surface of a part to improve corrosion resistance and appearance.
   

• Oxidation

  Creating a protective layer on metal parts (such as aluminum) through a chemical reaction, making them more resistant to wear and corrosion.
   

• Spraying (Powder Coating/Painting)

  Applying a powdered or liquid coating to parts, providing a protective and decorative finish that is durable and resistant to chipping or fading.
   

• Anodizing

  A specific oxidation process used on aluminum to form a thick, protective oxide layer, improving durability and wear resistance.
   

• Galvanizing

  Coating steel or iron parts with zinc to prevent rust and corrosion, commonly used in outdoor or harsh environments.
   

• Polishing

  Smoothing and shining the surface of a part to improve its appearance and make it more resistant to dirt and corrosion.
   

• Etching

  Using chemicals or lasers to create patterns or textures on the surface of a part, often for aesthetic or functional purposes.
   

• Passivation

  A chemical treatment process that removes contaminants and forms a protective oxide layer, typically for stainless steel parts, enhancing corrosion resistance.
