Key Applications of Nanotechnology in Mechanical Engineering:

1. Advanced Nanomaterials for Strength & Durability:

?? Carbon Nanotubes (CNTs): Used in composites for aerospace, automotive, and structural applications, CNTs are 100x stronger than steel but only a fraction of the weight.

?? Graphene Coatings: Offering unmatched thermal and electrical conductivity, graphene-based materials are being used for corrosion resistance, wear reduction, and even lightweight armor.

?? Nano-reinforced Polymers & Metals: These materials enhance mechanical properties, making components more resilient under stress and extreme conditions.

2. Nanotechnology in Lubrication & Wear Resistance:

?? Nano-lubricants: Engineered nanoparticles (e.g., tungsten disulfide, molybdenum disulfide) reduce friction and wear in mechanical systems, extending the lifespan of components.

?? Self-healing Coatings: Materials infused with nano capsules can repair micro-cracks in real time, preventing structural failure in pipelines, aircraft, and machinery.
