The use of nano-coatings to reduce frictional drag, increase speed and life span in high speed crafts

Today, nanotechnology is used as one of the newest and most practical methods to reduce frictional drag force, increase speed and life span of vessels. The coatings used in the floats should be resistant to seawater, salts, corrosive agents, water penetration and algae growth. The first and most important application of coatings on the vessels is to use them to reduce surface corrosion. Corrosion usually begins at the surface of the material and permanently reduces the life span of the materials used. Nanoparticle materials exhibit unique physical and chemical properties, which can improve the corrosion resistance of these materials. Nano-colors are one of these types of coatings used in marine industries. The use of nanotechnology in the color industry prevents clogging of pockets to float and prolongs the life of floats. Another way to improve the surface properties of marine vessels and increase their lifespan is to use nano-composite coatings. The most important application of the coatings on the vessels is to increase their speed due to the reduced floating resistance against frictional drag force. The friction drag force directly measures the amount of force needed to move the body. An effective new method for reducing drag forces is the use of nano coatings, which reduces the strength of the resistor and the amount of sediment formed on the floating body.
