Aequs offers special processing capabilities through its group company, Aerospace Processing India Pvt. Ltd (API). API is a joint venture between Aequs and Magellan Aerospace of Canada and is located in Aequs SEZ, Belagavi, Karnataka, India..
The company provides aerospace surface treatments that are not readily available in India. The fully integrated, scalable facility has been operational since 2009. This is the first and only third party facility approved by Boeing and Airbus in India. API was the first in India to achieve NADCAP accreditation for Chemical Processing, Surface Enhancement and NDT, which is widely demanded across the aerospace industry. API is also AS9100 certified.

TSA/Chromic/Boric/Sulphuric acid Anodizing
Anodizing is an Electrolytic process through which a layer of oxide is produced on the surface of the part to improve the properties of corrosion resistance. It improves adhesion properties of bonding, wear and tear resistance. Anodizing can be done on highly corrosive metals and the anodizing process creates and oxide on the surface of the part which prevents the metals from corroding. Based on the characteristic of a metal, different types of aqueous solutions are used. Anodizing on Aluminum and Aluminum alloys are done with Tartaric Sulphuric Acid or Chromic Acid and for Steel and Titanium metal parts, anodizing is done with Boric or Sulphuric Acid.
Aluminum/Titanium Etching, Alochrome & Alodine
To improve the traceability of the part/product and to make the metal active and to bring the grains on the surface, Etching is carried out on the parts. Marking is done through either chemical or non- chemical means like electro chemical etch marking, ink jet marking, marking with pens and Tagging on to Steel, Aluminum and Aluminum Alloy products and precise etching is done from a mixed acids on Titanium parts.
Prime, Paint, Moly Coat, Part Mark
To improve the corrosion resistant property and aesthetics of the component, Moly Coat and Paining is done either using solvent based paint or water based paint. Application of paint can be done using conventional spray or electrostatic or electrophoretic processes. Once the painting of the part or product is carried out, it is marked with a batch number for traceability.
Passivation and Salt Spray are standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings. Once the passivation is done by using a light coat of a protective material, such as metal oxide which creates a shell, it has to then undergo a corrosive attack in order to evaluate (mostly comparatively) the suitability of the coating for use as a protective finish. This corrosive attack is done by a Salt Spray test and the appearance of corrosion products (rust) is evaluated after a pre-determined period of time. Test duration depends on the corrosion resistance of the coating; generally, the more corrosion resistant the coating is, the longer the period of testing before the appearance of corrosion/ rust.
Cadmium and Zinc Nickel Plating
NADCAP accredited Cadmium and Zinc Nickel Plating, or, CAD and Zn Nickel Plating, are robust and versatile metal coatings that are widely accepted in the Aerospace industry. Plating is needed to improve strength of components, shield from radiation and enhance corrosion protection while increasing aesthetics. API specializes in Zinc Nickel Plating, one of the best corrosion resistant finishes available in the Aerospace Industry.
Robotic Shot Peening
Our state-of-the-art Robotic Shot Peening system is designed to support automated peening of a wide variety of components, even with most demanding process specifications. Compressive stress is induced to considerably reduce the risk of fatigue cracks during the operation of these components.
