CNC Custom Machining Parts Surface Treatment Types

Type II (MIL-A-8625, Type II) creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum. Type III (MIL-A-8625, Type III, Class 1/2 “hardcoat”) is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.

A hard coat anodize process that embeds PTFE to create a self-lubricating, dry contact surface with Type 3 hard coat’s protective properties. This finish can be used on aluminum alloys or titanium and increases the service life of the product. This finish conforms to the AMS-2482 Type 1 Hard Coat Anodizing with Teflon (Non-Dyed).

A surface finish for titanium per AMS-2488 Type 2 specification. Also called Tiodize, this finish increases fatigue strength and the wear resistance of a part. Titanium anodized parts are common in aerospace and medical device manufacturing. Non-pigmented titanium anodize finishes will dull shine.

Also known as buffing, a process of rubbing the surface of parts or utilizing a chemical action to produce a smooth and shiny surface, make the surface get significant specular reflection or reduce diffuse reflection in some materials.

Refers to an altering surface finishing process, spraying paint, pigment, or color to a solid surface as a colored protective layer, and can be done on metal or non-metal CNC machined components of any shapes, usually applied on aluminum, stainless steel and steel alloy parts. The purpose is to improve aesthetic appearance and prevent corrosion or oxidation.

A common chemical surface treatment method for steel and stainless steel, to remove ferrous contaminants or use a light coat of protective material to create a shell for enhancing the corrosion resistance or reducing the chemical reactivity.

A process of using an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode, to change the properties of the machining metal surface or build up thickness for undersized parts.

Provides corrosion resistance and good conductivity properties. Can be used as a base for paint. Can leave surface yellow/gold. Adds very little thickness, about 0.00001”-0.00004”. Chem film will conform to MIL-DTL-5541, TYPE I/II.

This is a process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

Black Oxide: Also known as blackening, gun bluing or hot blackening, a chemical process of forming a black conversion coating on stainless steel, copper and copper based alloys, zinc, powdered metals, silver solder, and ferrous materials, to improve corrosion resistance and minimize light reflection.

Conversion Coating: Also call as chromate conversion, the coating are used for metals converted to a protective layer through the chemical or electrochemical processes, primarily used as a corrosion inhibitor, decorative finish, or to retain electrical conductivity.

Bead blasting/Bead Blast: the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.

Abrasive Blasting/Sandblasting: the process or operation of propelling a stream of abrasive material composed of high-velocity sand-sizes particles against the metal surface under high pressure with blast equipment like air pressure system, to remove surface contaminants, clean metals or increase a texture, then change the smoothness or roughness of surface.
