Phosphating Process

We are the leading manufacturer of plating with passivation plant in chennai . We will manufacture the plants according to the customers requirement like 3ton,5ton and 8ton capacity per 12 hr.

The pink end point should be between 60-65 ml. If found less add more Meproche 245. Every 0.8 kg of Meproche 245 per 1000 liters of barh material gives rise in pointage (No. of ml of 0.1 N sulphuric acid), hence maintain the pointage between 60 and 65. Remove the oil and grease from the top of the bath by skimming, as and when generated.

Phosphate coatings are often used to provide corrosion resistance, however, phosphate coatings on their own do not provide this because the coating is porous. Therefore, oil or other sealers are used to achieve corrosion resistance. This coating is called a phosphate and oil (P&O) coating. Zinc and manganese coatings are used to help break in components subject to wear and help prevent galling. Most phosphate coatings serve as a surface preparation for further coating andor painting, a function it performs effectively with excellent adhesion and electric isolation. The porosity allows the additional materials to seep into the phosphate coating and become mechanically interlocked after drying. The dielectric nature will electrically isolate anodic and cathodic areas on the surface of the part, minimizing under film corrosion that sometimes occurs at the interface of the paintcoating and the substrate
