The motivation for this research work is to apply innovative process of Electroless Nickel (EN) coating on aluminium
(Al) cartridge cases used for releasing external stores on fighter aircraft. Aluminium, chosen for its lightweight properties,
electrical conductivity, non-corrosiveness, and compatibility with energetic materials, proves advantageous in defence
applications due to its high strength-to-weight ratio and softer composition compared to other metals. Nickel coating is
applied to enhance corrosion resistance, increase wear resistance, eliminate the cracks, blow holes and improve the overall
aesthetic appeal of the cartridge. Unlike traditional electroplating methods, novel EN methodology employed here operates
through an auto-catalytic reaction, eliminating the need for electricity during metal ion deposition. Before the introduction of
the EN coating, the use of bare aluminium cases led to defects such as blow holes or cracks on the cartridge surface. The EN
coating applied to the power cartridge case, serve as a thermal barrier without compromising the electrical conductivity of
the base material. The paper discusses the successful prevention of defects through a series of trials and emphasizes the
crucial role of EN coating on aluminium cartridge cases in emergency situations for releasing bombs from military aircraft.
Positive feedback received from users regarding the utilization of EN coating on Al cartridge cases proves the effectiveness
and reliability of the process. This process enhances the manufacturing technology to meet the specific and critical
requirements of users i.e. Indian Air Force (IAF).
