What Specific Surface Treatments can MIM perform?

Passivation

Chemical oxidation forms an inert oxide film

Stainless steel, nickel-based alloys

Improve corrosion resistance and maintain the original color of the metal

Anodization

Electrolytic oxidation to form a porous aluminum oxide layer

Aluminum and aluminum alloys

High hardness, insulation, colorable

Electroplating

Electrolytic deposition of metal layers

Steel/copper/stainless steel and other conductive materials

Wear-resistant + decorative + corrosion-resistant composite function

Coating

Physical/chemical deposition

Customized functions (insulation/conductivity/super hardness/self-lubrication)

Anodization

Generation of hard aluminum oxide layer

Significantly improves the wear resistance of aluminum parts

Sandblasting

High-speed jet abrasive

Remove oxide scale, roughen the surface, and enhance coating adhesion.

Bead Blasting

Sprayed glass/ceramic microbeads

Deburr, generate compressive stress, improve fatigue strength.

Media Blasting

Using a variety of abrasives

Environmentally friendly cleaning, does not damage delicate surfaces.

Polishing

Mechanical/chemical roughness reduction

High gloss, mirror finish

Electroplating

Decorative coating

High-end consumer goods, electronic components

Pad Printing

Curved surface printing of text/LOGO

Identification of complex-shaped parts

Laser Engraving

High-energy laser ablation forms deep marks

Permanent, wear-resistant, does not affect part functionality

Laser Etching

Shallow surface oxidation/discoloration

No physical deformation, suitable for precision functional surfaces
