How does thermal spraying reduce energy consumption?

When assisted with other processes such as additive manufacturing, thermal spraying reduces the energy consumption and raw material usage. Both thermal spray OEMs and service providers need to embrace the culture of durability as much as possible to minimize waste and recycle the critical raw materials.

How to reduce energy consumption during plasma spray?

Controlling the voltage fluctuation and improving the anode and cathode life is important to reduce the energy consumption during plasma spray and many nozzles have been designed to optimize the plasma spray process [ 44 ].

Can tungsten be recycled for thermal spray?

Tungsten is a rare element, and efforts are being made to salvage W for thermal spray through various means. One such effort [ 37] has been to recycle WC–Co directly from used cutting tools using a zinc melt method. Bond coats for thermal barrier coatings are typically sprayed with HVOF process through propane, propylene, or kerosene.

What is thermal energy storage?

Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks - can store thermal energy.

How much yttrium oxide is wasted during spray?

If the coating deposition efficiency was 60%, then about 800 tons of powder was wasted during spray. Eight weight percent of Y 2 O 3 in the powder means 64 tons of yttrium oxide (50 tons of yttrium after subtracting the weight of oxygen) was wasted in 2015 alone. Yttrium being a precious critical raw material cannot afford to be wasted.

Which industries use thermal spraying technology in 2024?

Sectors such as agricultural machinery, healthcare, electronics, and paper industries also make use of thermal spraying technology but the growth in these sectors by 2024 compared to 2016 is not as significant as it will be in the aviation and power sectors.
