where robustness meets durability
thermal spraying
what is thermal spraying?
Thermal spraying is the process of applying a coating material in powdered or wire form to a surface to improve or modify its properties. The surface coating process is typically performed using a thermal energy source such as a flame, plasma or arc to melt or vaporize the spray material. The melted or vaporized material is then sprayed onto the surface to be coated, where it emerges and cools to form a thin, homogeneous coating.
Thermally sprayed coatings are characterized by high surface hardness as well as excellent non-stick properties. Using metals, ceramics and polymers, our experienced Aalberts surface technologies team create the optimum protection for heavily stressed components in a variety of process variants.

We will cooperate with you in order to find the coating process to match your material. All kinds of surfaces can be coated using thermal spray: aluminum, steel, and other types of metals, but also glass, ceramics, plastics, and more. From initial sampling to series introduction, we will determine the relevant process steps together with you. We also support you in choosing the right spraying method such as flame spraying, plasma spraying or arc spraying. Upon request, we will supplement our technical services by a logistics concept with pick-up and delivery services tailored to your needs.

PlasmaCoat® thermal spraying for excellent non-stick properties
Our PlasmaCoat® thermal spray coating process comprises different coatings which are applied to components with varying degrees of roughness and different profiles with the aim of creating surfaces with excellent non-stick and traction properties as well as corrosion protection. Prior to thermal spraying applications, we clean the material and roughen up its surface. This results in the spray particles’ mechanical adherence to the surface and guarantees coating adhesion strength. An embedded metal or ceramic layer serves as a substrate for the anti-corrosion coating. Depending on the coating type and application, the coating thicknesses customary to thermal spraying range between one-tenth of a millimeter and several millimeters.
properties of thermal spray coatings
Our PlasmaCoat® spray coating process merges the extreme surface hardness and excellent wear protection of thermally sprayed metal or ceramic coatings with the non-stick and gliding properties of polymers and fluoropolymers. In this way, we prolong the service life of components subject to heavy mechanical loads. When mechanically reworked, PlasmaCoat® coatings can also replace hard-anodized layers. Precise diamond tools are usually required for high quality and clean reworking of the hard surfaces. Thanks to our comprehensive expert knowledge and high-quality tools, the results we achieve are accurate to one-thousandth of a millimeter.
By the targeted thermal spray coating of different materials, we also create other excellent functionalities, such as:
- Non-stick properties
- Improved tribological values
- Corrosion resistance
- Very low porosity
- Low degrees of roughness
- Resistance to temperatures
base materials suitable for thermal spraying
PlasmaCoat® coatings can be applied to almost all metallic materials as well as to CFRP components. Thermal spray coatings are primarily applied to aluminum, steel, stainless steel, cast iron, brass and copper. However, it is also possible to apply this type of coating to ceramics, glass or temperature-sensitive materials, such as (fiber-reinforced) plastics, wood or fabrics. We will find the appropriate procedure for your requirements, be it plasma spraying, electric arc spraying or flame spraying.
fields of application of thermal spraying
PlasmaCoat® is primarily used as a surface finish in the nonwovens industry. To allow for the safe and trouble-free transport of materials or webs made from plastics, textiles or paper, transport rollers and other relevant components require wear-resistant traction coatings. Depending on the type of application, non-stick and conductive properties might be required as well. Thermal spray coatings by Aalberts surface treatment create precisely these characteristics.

frequently asked questions - thermal spraying
WHAT ARE THE ADVANTAGES OF THERMAL SPRAYING?
Due to the wide range of possible materials and the targeted creation of characteristics, thermal spraying processes are superior to many other coating processes. Apart from metals and metal alloys, it is possible to process hard metals, ceramics and plastics.
WHICH BASE MATERIALS CAN BE COATED WITH THERMAL SPRAYING PROCESSES?
Almost all metallic base materials can be finished with thermal spraying (aluminum, steel, cast iron, brass, copper, etc.). However, it is also possible to coat ceramics, glass or temperature-sensitive materials, such as (fiber-reinforced) plastics, wood or fabrics. Since the coating adhesion is usually based on mechanical interlocking, the surfaces to be coated have to be roughened up by sandblasting.
IS THERMAL SPRAYING ALSO SUITABLE FOR THE REPAIR OF WORN COMPONENTS?
Thermal spraying is an excellent method for repairing worn components, as their original dimensions can be restored while protecting their surfaces against further wear and tear.
WHAT CHARACTERIZES THERMAL SPRAY COATINGS?
Thermal sprayed coatings are particulary characterized by high surface hardness. In addition, some properties such as temperature resistance, corrosion protection or wear protection can be achieved or improved by the coating process. Using metals, ceramics and polymers, our experienced employees create the ideal protection for components subject to heavy loads with different process variants.
