  2. INTRODUCTION

  3. Passivation is a term used to name the final chemical treatment of the metals, in order to make them more stable and resistance while physically exposure to air and other metals. There are various methods of passivation used to: To irradicate the chances of surface contamination of the metal To increase corrosion resistance To improve hardness To give a finishing touch

  4. But how to achieve this? Let’s take a look at the most common methods used in the best construction companies in Saudi Arabia: Anodizing The surface of aluminium, titanium and magnesium are passivated using this method of anodizing, in which the surface of the metal is changed instead of adding some coating on top. The top layer of the metal is cleansed in sulfuric or hydrochloric acid.

  5. Bluing Bluing is the conversion coating method used on steel materials. The top layer of steel is cleaned with acid and then dipped in another electrolyte solution resulting in a blue surface. The blued surface serves to reduce glare but is very thin, calling the need for regular treatments of oil to maintain corrosion protection.

  6. Galvanizing Hot-dip galvanizing is the process of dipping steel or iron parts into molten zinc. This plain flat grey, rough finish of zinc gives corrosion protection on mild steel, serving the ultimate aim of passivation.

  7. Chrome Plating Chrome plating is a widely used passivation process not only on metals but plastics as well. Chrome plating results in the shiny, polished surface that you see on the kitchen faucets. Chrome plating is done with chromium and hard chroming is yet another technique used to coat the dynamic parts like bearings and shafts.

  8. These are the most common passivation techniques utilized by the best mechanical construction companies in Saudi Arabia and each of it has its own advantages and varying cost limits. Thus, choose the best that serves you the most, after considering your material and its requirements.
