Duplex Nickel Hard Chrome Plating

To Increase corrosion resistance highly leveled & ductile duplex Nickel plating is being done. Nickel is deposited as a semi bright and bright layer on the motorcycle front fork inner tube, shock absorber piston rods and hydraulic pistons and cylinders as an undercoat to Hard Chrome Plating.

This process is known as functional Nickel Plating.

The Character of Plating is influenced by Plating Condition, Nature of substrate, composition of solution and its purity

To control condition of plating - We have fully best in class ISO/TS -16949 certified automated plants.

Hard Chrome Plating

Chromium layers of high thickness used for engineering purpose is known as Hard Chrome Plating. This hard chrome plated layer is an alloy of chromium, oxygen and hydrogen. Due to presence of oxygen in deposited chrome matrix, hardness and wear resistance of chrome plating is more than pure chrome metal ingot; hardness we achieve is 950-1050 HV.

In our process due to special bath chemistry and process control we do plate micro cracked chromium of cracked density around 1000 nos. per linear centimeter. Micro cracked chromium is a special type of plating having continuous and uniform network of cracks is good for corrosion resistance and lubrication due to oil retention in piston application.

Silver plated Components

Why good Silver plating is required for contacts and connections in high voltage circuit breakers

  1. The Temperature rise allowed is considerably higher (65C) for silver plated connections than un-plated copper connections (30C).
  2. Silver plated copper does not oxidize as rapidly as bare copper.
  3. If we use only copper component then copper oxidize and reduce the conductivity.
  4. Oxidized copper connections increases electrical resistance and temperature rise of conductors.
  5. For sliding contacts Hard Silver Plated contacts withstands the stress of moving joints.

The electrical conductivity and Solderability of the Silver Plated components are maintained by process control and bath chemistry. We also have a special plating process for hard silver plating having hardness ≥ 100 HV as required by some customer.
