Repair
Wear-resistant coatings by thermal spraying
Coefficient of friction
Whether repairing cylinders, shafts or other critical machine components, thermal spraying offers several advantages. It not only extends the service life of components but also improves their performance under demanding conditions. In addition, it minimises the need for costly replacements and reduces machine downtime, which is vital for businesses that depend on continuous, efficient operation.
This technique is often used to apply wear-resistant coatings to machine components, tools and other substrates exposed to abrasive conditions.
The most common thermal-spraying processes for wear-resistant applications are flame spraying and HVOF (High-Velocity Oxy-Fuel) spraying. During the process, a wear-resistant material such as tungsten carbide, ceramic or a metal alloy is heated in powder or wire form and accelerated towards the surface using a flame or high-velocity gas jet.
Controlling the coefficient of friction through thermal spraying involves applying coatings with specific properties to reduce or increase friction, depending on the application. This technique is crucial in industries where friction affects performance, wear and efficiency.
Electrical insulation
Electrical insulation by flame spraying is often used where traditional insulation methods are impractical or where a thin but effective insulating layer is required. The process provides a durable and reliable solution for protecting components against unwanted electrical conduction.
Chemical attack
In machine maintenance, applying the right thermal-spray coatings is crucial for preventing chemical attack and preserving the integrity of machine components, especially in environments where exposure to corrosive chemicals is a constant concern.
Corrosion protection
Surface roughness
Thermal spraying makes it possible to apply protective coatings of high-quality materials such as zinc, aluminium or alloys to metal machine components. These coatings form an effective barrier against corrosive influences including moisture, chemicals and atmospheric exposure.
Using thermal spraying to achieve specific surface-roughness properties is a valuable machine-maintenance technique that we use for:
-
Improved wear resistance.
-
Optimised grip.
-
Adjusted surface roughness for improved lubricant retention.
-
Creating functional surface textures.
-
Reduced friction on sliding surfaces.
