Finishings
Abrasive Blasting (Sandblasting, Bead Blasting)
Propelling abrasive media at high velocity to clean, shape, or roughen surfaces
Advantages:
- Effectively removes contaminants and old coatings
- Creates uniform surface texture
- Improves adhesion for subsequent coatings
Disadvantages:
- Can cause material distortion if not controlled
- Requires proper containment for dust/debris
- May alter material dimensions
Common Applications: Automotive parts preparation, rust removal, architectural restoration, surface preparation before painting
Polishing/Buffing
Smoothing surfaces using abrasive materials to create a reflective finish
Advantages:
- Achieves mirror-like finishes (up to Ra 0.05μm)
- Enhances aesthetic appeal
- Reduces surface friction
Disadvantages:
- Labor intensive and time-consuming
- May remove too much material if not controlled
- Requires multiple stages for best results
Common Applications: Jewelry, luxury watches, medical instruments, high-end consumer products, optical components
Brushing
Creating linear patterns on metal surfaces using wire or nylon brushes
Advantages:
- Creates decorative satin finish
- Hides minor surface imperfections
- Less expensive than polishing
Disadvantages:
- Shows fingerprints and smudges easily
- Difficult to maintain consistent pattern
- Less corrosion resistant than polished surfaces
Common Applications: Architectural metals, kitchen appliances, elevator doors, decorative panels, consumer electronics
Treatments
Heat Treating (Annealing, Hardening, Tempering)
Controlled heating and cooling processes to alter physical and mechanical properties
Advantages:
- Significantly improves material hardness and strength
- Relieves internal stresses
- Enhances machinability and ductility
Disadvantages:
- Can cause dimensional changes
- Energy intensive process
- May require secondary operations
Common Applications: Cutting tools, gears, springs, bearings, structural components, aerospace parts
Passivation
Chemical process that creates a protective oxide layer on stainless steel and other metals
Advantages:
- Enhances corrosion resistance
- Removes free iron and contaminants
- Non-toxic and environmentally friendly
Disadvantages:
- Limited to specific metals (primarily stainless steel)
- Does not provide decorative finish
- May require precise chemical control
Common Applications: Medical devices, food processing equipment, pharmaceutical equipment, marine components
Plating (E-coating)
Zinc Plating
Electroplating process that deposits a layer of zinc onto metal surfaces
Advantages:
- Excellent corrosion resistance (sacrificial protection)
- Relatively low cost
- Can be further enhanced with chromate conversion
Disadvantages:
- Less durable than some other platings
- Limited temperature resistance
- Not suitable for highly acidic environments
Common Applications: Automotive fasteners, hardware, electrical components, construction materials
Nickel Plating
Electroplating process that deposits nickel onto metal surfaces
Advantages:
- High hardness and wear resistance
- Good corrosion protection
- Can be polished to high luster
Disadvantages:
- Can cause allergic reactions in some people
- Environmental concerns with waste disposal
- More expensive than zinc plating
Common Applications: Automotive trim, electronics, hydraulic components, molds and dies
Chrome Plating
Electroplating process that deposits chromium onto metal surfaces
Advantages:
- Exceptional hardness (up to 1000 HV)
- High corrosion and wear resistance
- Bright, decorative appearance
Disadvantages:
- Environmental concerns (hexavalent chromium)
- Complex process requiring skilled operators
- Higher cost than many other platings
Common Applications: Automotive trim, bathroom fixtures, industrial tooling, hydraulic rods
Copper Plating
Electroplating process that deposits copper onto metal surfaces
Advantages:
- Excellent electrical conductivity
- Good thermal conductivity
- Often used as undercoat for other platings
Disadvantages:
- Tarnishes easily without protective coating
- Limited corrosion resistance on its own
- Requires careful surface preparation
Common Applications: Printed circuit boards, electrical components, decorative items, undercoat for nickel-chrome plating
Gold Plating
Electroplating process that deposits a thin layer of gold onto metal surfaces
Advantages:
- Superior corrosion resistance
- Excellent electrical conductivity
- Prestigious appearance
Disadvantages:
- Very high cost
- Soft and susceptible to wear
- Requires precise thickness control
Common Applications: Electronics connectors, jewelry, aerospace components, high-reliability electrical contacts
Silver Plating
Electroplating process that deposits silver onto metal surfaces
Advantages:
- Highest electrical conductivity of all metals
- Good thermal conductivity
- Attractive appearance
Disadvantages:
- Tarnishes easily
- Relatively soft and susceptible to wear
- Higher cost than base metal platings
Common Applications: Electronic components, RF connectors, silverware, jewelry, mirrors
Other Coatings
Powder Coating
Dry finishing process where electrostatically charged powder is applied and then cured with heat
Advantages:
- Extremely durable and resistant to chipping
- Environmentally friendly (no VOCs)
- Wide range of colors and textures
Disadvantages:
- Requires heat curing (not suitable for heat-sensitive materials)
- Difficult to achieve thin coatings
- Higher initial equipment cost
Common Applications: Appliances, automotive parts, outdoor furniture, bicycles, architectural elements
Anodizing
Electrochemical process that converts aluminum surface into a durable, corrosion-resistant oxide finish
Advantages:
- Excellent corrosion and wear resistance
- Can be dyed in wide range of colors
- Electrically insulating
Disadvantages:
- Limited primarily to aluminum
- Can be damaged by strong acids or bases
- Color may fade with UV exposure

Painting
Application of liquid paint to surfaces for protection and decoration
Advantages:
- Virtually unlimited color options
- Can be applied to almost any material
- Relatively low cost
Disadvantages:
- Less durable than other coatings
- May contain VOCs (environmental concerns)
- Requires careful surface preparation
Common Applications: Automotive bodies, industrial equipment, consumer products, architectural elements
