Electrolytic Plasma Technology deposits dense, conformal coatings to various metals and alloys.
These coatings can be deposited at rates of up to 2 μm/sec. and thickness of the coating can be controlled as per the needs of the customer. The adhesion characteristics of CAP applied coatings are very high and coated materials can be formed, and even drawn, without worrying about delamination of the coating. EPT coatings can be applied as pure metals, layered metals, or alloys, and can be applied to materials of a large variety of shapes and sizes.

Mechanical Properties
Mechanical Properties such as tensile, torsion and ductility properties are not altered during the EPT process. The coating forms a metallurgical bond with the substrate which gives it excellent adhesion. In addition, no brittle intermetallic layers are formed in the coating (below).

Comparison of corrosion resistance of CAP applied Zinc Coating vs. HDG coating (ASTM B117).
EPT coatings are very effective against corrosion.
In fact, EPT coatings from CAP have been proven to last twice as long as HDG coatings of comparable coating weights in salt spray tests (According to ASTM B117).
Surface morphology
Surface morphology of the coating eliminates the use of borax, phosphating, or other lubricant carriers during drawing. It also helps us in directly drawing a rod to a small wire size.
