- Growing Preference for Thermal Spray Coatings over Chrome Plating is Driving Market Growth
Market CAGR for thermal spray is being driven by the growing preference for Thermal Spray coatings over chrome plating. Because of its oxidation, corrosion resistance, tear, and dimensional reclamation capabilities, strong chrome plating has been a viable industry solution for many years. It can be done at a fair cost per surface area unit, although it does have some restrictions in component size, thickness build-up, and operational performance. Growing environmental concerns, severe rules imposed on the chrome plating process and disposal of its byproducts, as well as rising costs, are increasing demand for Thermal Spray coatings.
As a result, it has become critical for the industry to develop alternative techniques that produce hard chrome plating with comparable properties but without the associated dangers. Thermal Spraying technology is gradually becoming a viable alternative to this approach, with the potential to provide complementary methods for component safety and reclamation to the chrome plating sector. Thermal coatings last far longer than chrome plating. Furthermore, chrome plating contains micro-cracking inside the plating layer, allowing high or low pH corrosive substances to enter the plating and harm the substrate. Micro-cracking can be seen in the accompanying photomicrograph.
Thermal coatings have substantially higher fatigue resistance than chrome plating. Because high-velocity oxygen fuel (HVOF) coatings apply a compressive load to the substrate, component life is actually extended by resisting fracture start against fatigue failure. Chrome plating introduces tensile pressure onto the surface of the substratum, which triggers fracture formation and may result in premature failure. End-use industries migrating from chrome plating to Thermal Spraying are expected to boost market expansion.
The increasing use of thermal spray coatings in the energy & power industry to protect gas turbines and power generators from erosion, wear, and any type of laceration drives market growth. Wind turbines have several components that are exposed to dust, hail, wear, and atmospheric pollution, such as blades, towers, rotors, yaw drives, and gearboxes. Thermal coatings improve the operation and longevity of equipment and components for a longer period of time and increase the operational life of the equipment. The coating for gas turbines is often applied using High-Velocity Oxygen Fuel (HVOF) and Plasma Spray process techniques.
Furthermore, any expansion in the power industry will promote the growth of the Thermal Spray coatings market.
For instance, According to the Wind Energy Council (GWEC) study published in 2020, it is expected that around 60.4 GW of wind energy capacity was constructed ly in 2019, representing a 19% increase over 2018, and total wind capacity was 651 GW in 2019, representing a 10% increase over 2018. Such high demand for electricity will drive the growth of the energy and power industries, which will in turn drive the growth of the Thermal Spray coating market.
The Global Thermal Spray Market is poised for growth as industries increasingly adopt advanced coating technologies to enhance the durability and performance of components across various applications.
