Hard Chrome plating (also known as “Industrial Chrome”) is applied to ferrous and nonferrous materials to improve wear and abrasion resistance, reduce friction, prevent seizing and galling, and to restore the dimensions of undersized parts.

Hard Chrome can be applied to all types of stainless steel alloys, most ferrous metals, and some nonferrous metals including copper and brass. Please contact our application engineers to discuss the feasibility of applying Hard chrome to other metals such as aluminum.

Deposits can be applied from 0.002 to 0.8mm thickness for wide range of application. The thinner deposits being used to substantially increase the life of components in wear application or corrosive environment, and the thicker deposits being used for salvage and repair of worn, damaged or mis-machined components.

Our hard chrome hardness from 900 ~ 1200 HV.

  • Chrome was designed as a high speed, etch free replacement for ordinary chrome solutions.
  • By depositing chrome the corrosion resistance properties are enhanced for the more demanding atmospheric conditions.
  • Micro cracked deposit minimum 1000 cracks per linear inch. Vickers Hardness 950 – 1150. Increased corrosion resistance. Increased wear resistance. Less edge build up and improved distribution.
  • Chrome process was cover up the hydrogen embrittlement issue.
  • All α – Chrome product was hydrogen embrittlement relief after the plating.

Hydrogen Embrittlement:

Hydrogen embrittlement can occur when hardened tool steel (Rc 52 or harder) is plated with industrial hard chrome. Stresses caused by the formation of hydrogen in the deposit can render the component susceptible to fracture. Although overlooked by many platers, this problem is easily solved by α – Chrome

Wear Resistance :

Chrome has almost twice the wear resistance of conventional micro crack hard chrome. The effect of the micro cracks improves the corrosion resistance.. In a conventional hard chrome the corrosion between the coating and the substrate escapes through the limited number of cracks, and if the corrosion rate is high the corrosion will cause large blisters of rust pushing the chrome away from the surface as the products of corrosion take up more space than the original material. With the micro crack coating the corrosion has many more routes of escape and the damage caused by corrosion is significantly reduced.

Surface Hardness :

Chrome as deposited has a surface hardness of 950 – 1150 Vickers which is significantly harder than a conventional hard chrome of between 600 – 800 Vickers, thus resulting in improved wear resistance.

Corrosion Resistance :

The resistance to corrosion depends upon the condition of the substrate and the thickness of the deposit. Micro Crack Hard Chrome is so called because of the structure of the deposit. As the electroplating process takes place the Chromium being deposited becomes highly stressed. At approximately 2 microns deposit the coating cracks and continues to crack throughout the cycle time at 2 microns deposit. The cracks are not continuous to the surface. The number of cracks per linear inch will be a minimum of 1000.

Part that under Chrome process will having a corrosion resistance 50% more higher than normal hard chrome.
