Central Kentucky Processing has offered quality plating and metal finishing services for the automotive industry for more than 30 years.

Nickel Plating:

At Central Kentucky Processing, you have a choice of quality nickel plated finishes:

Electroless Nickel:

Electroless Nickel is an autocatalytic chemical technique used to deposit a layer of nickel-phosphorus or nickel-boron alloy on a solid work piece. Central Kentucky Processing’s process is a mid phosphorus bath at 6-9 %. This type of plating service has several advantages such as free from flux density and power supply issues, even coating on parts surface, deposit non-conductive surfaces, and more.

Electrolytic Nickel:

Electrolytic Nickel is a technique of electroplating a thin layer of nickel onto a metal object. The nickel layer can be decorative, provide corrosion resistance, wear resistance, or used to build up worn or undersized parts of salvage purposes.

Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. Once the piece has been prepared it is immersed into an electrolyte solution and is used as the cathode. The nickel anode is dissolved into the electrolyte in form of nickel ions. The ions travel through the solution and deposit the cathode.

Zinc Plating:

Zinc plating is the process of covering substrate metals (steel, iron, etc.) with a layer or coating of zinc to protect the substrate from corrosion. Zinc coatings prevent corrosion of protected metal by forming a physical barrier and acting as a sacrificial anode. Zinc and iron/steel are joined and placed in an electrolyte, in which the zinc becomes the anode and the steel the cathode.
In the automotive industry, zinc plating is used as a cost-effective method to protect key components, such as brake calipers, brake pipes and power steering. Many zinc plating processes have been used extensively for heavy electrical transmission components.

Zinc Phosphate:

Zinc Phosphate is the process of converting a steel surface to iron phosphate. This is mostly used as a pretreatment method in conjunction with another method of corrosion protection. A layer of phosphate coating typically includes iron, zinc, or manganese crystals.

Black Oxide:

Black oxide is a conversion coating that is used for appearance and to add mild corrosion resistance to minimize light reflection. It is used for ferrous materials and is impregnated using oil to achieve maximum corrosion resistance. It provides a matte deep black appearance, which is available in rack or barrel.

Black oxides are used where component accuracy and tolerance are paramount, compared to painting methods. This method is used in fasteners, weldments, tooling and casting where oil retention and appearance are essential.
