Advantages of zinc aluminum flake coating.

Different advantages of zinc aluminum flake coating are as follows :

  1. No Hydrogen embrittlement – The treatment process of zinc aluminum flake coating do not involve treatment with acid for removal of corrosion products like mill scales, rust. Mechanical cleaning (shot blasting, grit blasting) followed by coating avoids the risk of hydrogen embrittlement.
  2. Overall coverage – The coating process is non electrolytic. Articles are coated by dip mode of application or spray mode of application depending on size, weight of article. The articles are coated ensuring complete coverage.
  3. Corrosion resistance – The corrosion resistance is higher due to overall coverage and also due to sacrificial protection of zinc /aluminum flakes. The film structure is like brisk wall minimizing penetration moisture. The film also has self healing property.
  4. Thermal stability – Cured film of zinc aluminum flakes do not changes its properties even at higher temperatures. There is no degradation in corrosion resistance property.
  5. Excellent adhesion and recoat ability – Zinc aluminum flakes coating film adheres firmly to metal surface. It has also excellent recoat ability. Top coat with different lubrication properties can be applied on zinc aluminum flake coating to further enhance different properties.
  6. Free from pollution – The water-based zinc aluminum flake coating process do not involve generation of waste water. The coating is free from water and air pollution.

Generally zinc aluminum flake coating process involves cleaning to remove oil, shot blasting to remove rust/mill scales, coating and curing. Desired properties are achieved essentially with two coats. The properties are further enhanced by application of suitable top coat.

New Generation Self-pH-Regulating Mirror Bright Finish Midphos Electroless Nickel Plating (ENP): Ginplate NI 4320 AutoP

GINPLATE NI 4320 AutoP is a Midphos, self-pH-regulated electroless nickel-plating (ENP) process, which provides a mirror bright finish.

Midphos ENP is commonly used on components exposed to mild environment for corrosion/wear resistance with an aesthetic appearance.

Electroless Nickel plating is an auto catalysed redox process that deposits an even layer of Nickel-phosphorus alloy coatings on a properly prepared surface. pH plays an important role in any redox process and it tends to change during the course of the chemical reaction due to generation of H+/OH– ions in the reaction vessel. During electroless nickel plating, the pH drops down due to generation of H+ ion, which needs readjustment by adding Ammonia or other base to maintain the alloy composition and plating speed. Hence, an auto-pH-regulated ENP process was a long-standing demand of ENP platers.

GINPLATE NI 4320 AutoP is specially designed to produce a consistent midphos EN deposits at a very good plating speed without any additional replenishment of Ammonia. The carefully formulated additives and buffer system of GINPLATE NI 4320 AutoP provides an excellent pH and bath stability without compromising the quality and speed of the plating. Mid Phosphorus ENP acts as a low-cost alternative for decorative and functional applications.

The GINPLATE NI 4320 AutoP is supplied as three separate liquid concentrates: GINPLATE NI 4320 AutoP A, GINPLATE NI 4320 AutoP B, and GINPLATE NI 4320 AutoP C.

CHARACTERISTICS OF COATING

  • Self-pH-Regulated process
  • Robust and Hybrid buffer system
  • Good plating Speed (15 – 22 μ/hr)
  • Phosphorous content 4.5 – 8.5% w/w)
  • Mirror bright finish
  • Long bath life (10 MTO)
  • Low operating cost
  • Good wear and abrasion resistance
  • Suitable for plating on wide variety of substrates, SS, MS, CS, Cu alloy & Al alloy
  • P-Content may be fine-tuned and controlled as per requirements of jobs.

 ADVANTAGES

  • No Ammonia is required to maintain the pH. Low maintenance cost and easier to maintain plating speed and alloy composition due to constant and consistent pH over the longer bath age.
  • Uniformity, hardness and corrosion/wear resistance makes it ideal for the parts or components that function under constant pressure or dynamic condition.
  • Plating with ENP can often eliminate the need for machining or polishing due to its good surface finish and uniform thickness distribution.
  • Midphos ENP provides large flexibility of thickness, volume, and alloy composition of the plating on metal/conducting surface. It can easily fill recesses or pits on the metal surfaces. This allows its application in a wider variety parts of industrial applications.

Zinc Aluminum Flake Coatings

Use of ferrous and non- ferrous material is unavoidable in the industry due to its availability, strength, durability, work-ability and ability to recycle. Automobiles, bridges, house- hold appliances, power generation equipment’s, railways, engines etc. are manufactured using ferrous and non -ferrous materials by adjusting metal properties in terms of hardness, flexibility, resistance to corrosion, weight to strength ratio etc.

Loss of metal due to various types of corrosion processes is a perennial problem in the industry. Thousands of dollars are wasted due to loss of metal (corrosion) and also thousands of dollars are invested in protecting the metal from corrosion. This in turn increases the life span of manufactured items, avoids the probable risk of accident.

Use of different types of fasteners, nuts, bolts, clips are necessary to manufacture different articles. The adequate strength required for the articles is provided by different sizes of fasteners, nuts and bolts.  Fasteners are subjected to failure due to atmospheric corrosion, hydrogen embrittlement, temperature variations and bi- metallic corrosion.

Different types of phosphating systems and also painting systems with different types of resins, film thickness varying from few microns to few millimeters are used to protect the main structure. However higher film thickness of any coating is a limiting factor for fasteners.

 Different types phosphating, blackodizing, zinc plating followed by passivation layers are used to improve the corrosion protection of fasteners. However, zinc plating has limitations in terms of corrosion protection and possibility of hydrogen embrittlement. Adverse effect on environment due to use of hazardous chemicals also needs to be considered while using such coatings.

Zinc aluminum flake coating is developed with the extensive research to provide protection against all types of corrosion for fasteners, brake disc etc with a very thin film of 6~10 microns. Zinc aluminum flakes with water or solvent based, binders free from hexavalent chromium (environmentally friendly) and adequate additives to improve different properties are widely used in the industry. Even at low film thickness zinc aluminum flake coating provides excellent protection against corrosion considering different environmental cycles. Zinc aluminum flake coating also helps in preventing bi metallic corrosion.
