Surface Finishes	Description	Services	Applicable Materials
Anodized	Electrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.	CNC Machining, Sheet metal	Aluminum
Black Oxidized	Chemical bath that creates a black oxide coating on metal to improve corrosion resistance.	CNC machining, Sheet metal	Steel, Iron
Alodine	Chemical treatment process providing corrosion protection and surface preparation for paint adhesion.	CNC machining, Sheet metal	Aluminum, Aerospace Alloys
Passivation	Chemical treatment to enhance the corrosion resistance of metals by removing free iron from the surface.	CNC machining, Sheet metal	Stainless Steel, Other Corrosion-resistant Alloys
Powder Coating	Dry finishing process using powdered paint to provide a high-quality, durable finish.	CNC machining, Sheet metal, Injection molding	Metals, Some Plastics
Spray Paint	Application of paint for aesthetic improvements and protective coatings.	CNC machining, Sheet metal, Injection molding, 3D printing	Metals, Plastics, Wood
Electroplating	Uses electric current to reduce dissolved metal cations to form a coherent metal coating.	CNC machining, Sheet metal	Metals
PVD	PVD coatings are typically very hard, significantly enhancing the wear resistance of the substrate.	CNC machining	Metals
Heat treatment	Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.	CNC machining	Metals
Carbonitriding	Enhanced Surface Hardness, Improved Wear Resistance, The depth of the hardened layer is usually shallower than that achieved by carburizing, typically ranging from 0.07 to 0.5 mm (0.003 to 0.02 inches).	CNC machining, Die casting	Metals
Polish	Polishing, Mirror polishing (Ra0.4)	CNC Machining	Metals, Plastics
Brush	Mechanical polishing that produces a unidirectional satin finish.	CNC machining, Sheet metal	Metals
