Why Thermal Spray
In industrial production and mechanical engineering, wear is a critical issue that reduces material performance and imposes significant economic burdens on businesses. Wear causes surfaces to deform over time, tolerances to deteriorate, and ultimately leads to premature equipment failure. This situation not only increases maintenance costs but also results in production downtime and loss of efficiency.
Traditional methods to combat wear—such as heat treatment, surface hardening, or complete part replacement—are often costly and offer limited solutions. At this point, thermal spray coating technology provides long-lasting and cost-effective protection by enhancing the surface properties of engineering materials. So, why choose thermal spray coating? Because this method offers a more flexible, affordable, and high-performance solution compared to alternatives.
Types of Wear and the Problems They Cause in Industry
Wear occurs through different mechanisms, each causing serious damage in various industrial applications.
The Global Economic Impact of Wear
Wear causes trillions of dollars in economic losses worldwide every year. According to research:
In the USA, annual losses due to industrial wear exceed $500 billion.
In Europe, wear in power plants reduces energy efficiency by 5–10%, resulting in an additional annual cost of €60 billion.
In the mining sector, replacing worn equipment accounts for 30–40% of maintenance budgets.
These figures demonstrate that preventing wear is not only a technical challenge but also an economic necessity.
Why Thermal Spray Coating?
Thermal spray coating is a protective layer formed by melting powdered materials and spraying them onto a surface at high speed. It is one of the most effective solutions to wear problems. So, why choose it?
Superior Wear Resistance
Tungsten carbide (WC-Co), chromium oxide (Cr₂O₃), and ceramic coatings provide excellent protection against abrasive and erosive wear.
For example, WC-Co coatings applied to crusher jaws used in mining can increase wear resistance by up to 10 times.Corrosion and Chemical Resistance
Nickel alloys and stainless steel coatings prevent corrosion in acidic and saline environments.
Thermal spray coatings on oil pipelines can extend their lifespan by up to 20 years.High Temperature Resistance
Thermal Barrier Coatings (TBC) offer resistance to temperatures up to 1,500°C in gas turbines and jet engines.Cost Effectiveness
Saves up to 70% compared to purchasing new equipment.
Extends maintenance intervals and reduces production downtime.Environmentally Friendly and Sustainable
Reduces waste material.
Allows reuse of old parts through recoating.
Industrial Applications of Thermal Spray Coating
Aerospace: Coatings on turbine blades protect against high temperatures and erosion.
Automotive: Prevents adhesive wear in pistons and cylinders.
Energy: Increases corrosion and erosion resistance in steam turbines.
Medical: Biocompatible coatings extend the lifespan of implants.
Conclusion: Why Choose Thermal Spray Coating?
Wear is a major issue that directly impacts industrial efficiency and profitability. While traditional methods offer limited solutions, thermal spray coating technology stands out with its high performance, long lifespan, and cost-saving benefits.
Why thermal spray coating? Because it:
✔ Minimizes economic losses caused by wear.
✔ Extends equipment life by 3 to 5 times.
✔ Dramatically reduces maintenance costs.
✔ Is an environmentally friendly and sustainable solution.
Thermal spray coating is the future of engineering materials. By adopting this technology, industries can enhance their competitiveness and achieve resource efficiency on a global scale.
