Abstract
Thermal spray coatings techniques are groundbreaking solutions for a multitude of stumble blocks in various industries.In this article authors reviewed various applications of thermal spray coatings such as automotive, biomedical, power generation and aerospace industry to overcome problems like tribological aspects, corrosion, heat losses, etc. Thermal spray coating will enhance the operating life of the components like in gas turbine industry and mechanical properties of components, increase the thermal efficiency by insulation in engines.It also helps to avoid allergic reactions to patients in orthopedic implants.Moreover, after thermal spray coating waste packages and canisters suitable to sustain the nuclear criticality for transportation, aging and disposal and reduction in friction and wear to increase the life of components in quagmire situations.These are various coating techniques i.e.HVOF, TWAS, FS, APS, CGS and VPS used in different applications to enhance or restore material/mechanical properties of particular component.
