Thermal Spray


Description :


In the modern Industrial world, engineering components are prone to more rapid surface degradation due to mechanisms such as wear, oxidation, corrosion or failure under an excessive heat load. As a consequence, in an effort to achieve enhanced performance in terms of productivity, efficiency etc., surface modification technologies have been attracting a great deal of attention as they present a cost-effective way to combat degradation modes such as above without sacrificing the bulk properties of the component material. Thermal spraying is one of the most versatile coating technique and finds wide ranging applications in numerous industry sectors.


In the thermal spray processes, electrical, chemical or mechanical energy is used to produce a high velocity gas jet. The coating material is introduced into this gas jet, usually in powder form. Particle-gas interaction lead to heat and momentum transfer from the gas jet to the particles and these accelerated particles are sprayed onto the substrate surface. On impact, thermal and kinetic energies of the particles are used for the formation of splats. These splats adhere to the substrate, and subsequently to each other to form the coating.
