Painting | Spraying paint, pigment, or color to a solid surface as a colored protective layer. |
Passivation | Remove ferrous contaminants or use a light coat of protective material to create a shell. |
Powder Coating | A functional and decorative finish that is applied as a free-flowing, dry powder. |
Anodizing | Type II (anodizing color or clear) or Type III (anodizing hard coat). |
Polishing | Produce a smooth and shiny surface. |
Black Oxide | Forming a black conversion coating on metal parts. |
Bead Blasting | Removing surface deposits by applying fine glass beads at a high pressure. |
Abrasive Blasting/Sandblasting | Smoothing and cleaning a hard surface by forcing solid particles across that surface. |
Electroplating/Plating | Form a thin coherent metal coating on an electrode. |
Brushing | Polishing the metal with grit resulting in a unidirectional satin finish. |
