· Conformance with requirements for Commercial and Military Specification Plating
Metal Finishers of Atlanta, Inc. can accommodate all of the above processes for large and small volume runs, highly machined precision parts, prototypes and parts requiring special handling. Expedited Services are also available upon request.
Anodizing is an electro-chemical process that uniformly converts an aluminum surface to an aluminum oxide film. Anodizing provides corrosion and abrasion resistance, increases paint adhesion, and improves the cosmetic appearance. Annodizing aluminum also increases wear resistance, provides electrical insulation, and may be dyed various colors for cosmetic purposes. Please note that dye does not provide any additional corrosion or abrasion protection. ( Applicable Specification: MIL-A-8625, Type II & Type III )
Regular (Type II) anodizing produces an aluminum oxide coating that ranges from .0004” - .0008” thick. The aluminum oxide coating is hard, dense, non conductive and has very good wear resistance.
Hard (Type III) anodizing produces an aluminum oxide coating that ranges from .0008” - .0025” thick. The advantages of using Type III, rather than Type II, are that it is harder, more dense, and has superior wear resistance. A disadvantage is that as thickness increases, the coating becomes brittle and may crack when flexed or forcefully impacted.
Zinc electro-plating is a process that deposits zinc metal on steel. It is used for corrosion resistance and improving cosmetic appearance. Thickness ranges from .0002” - .0015”. Corrosion resistance is based on the thickness of the zinc plated on the part and the color of chromate applied after plating. The darker the chromate; the more corrosion resistance it provides. Yellow chromate provides more corrosion resistance than clear chromate. (information on salt spray testing times is available upon request.) Wear resistance of zinc plating is moderate.
A chemical process that coats aluminum with a corrosion resistant film that can range in color from aluminum white to iridescent gold, depending on customer need. The darker the chromate; the more corrosion resistance it provides. (information on salt spray testing times is available upon request.) Advantages include superior paint adhesion and excellent corrosion resistance with electrical conductivity retained on all surfaces. However, wear resistance is poor.
A chemical process of depositing nickel metal onto steel, aluminum, copper and brass. Our mid-phosphorous plating bath produces a semi-bright finish. Thickness ranges from .0002” - .0015”. Electroless Nickel Deposits uniformly on all surfaces and provides excellent wear resistance, lubricity, and corrosion resistance.
A chemical process for removing surface contamination, primarily iron particles, from stainless steel. The passivated surface has excellent corrosion resistance.
A process for adding a thin coating of Teflon on type II and III Anodize and electroless nickel. The teflon coated surface has excellent wear resistance, and increased lubricity.
