Different Ways That Surface Treatments Can Be Used
A variety of surface treatments can improve the performance of a compound. Some of these treatments include coupling agents to help improve the distribution of reinforcing materials and fillers. Fillers are a vital component of many compounds and serve a variety of critical functional roles. Some surface treatments are suitable for a particular type of compound, while others are designed to improve specific properties, such as conductivity or moisture resistance. Depending on the application, multiple treatments may be applied to particles to mitigate pH or other interactions with reagents.
Flame-based surface treatments use high-frequency arcs to melt materials that are mechanically bonded. The materials are typically ceramic or metal. The wire or powder feedstock is ignited and melts, forming a film that adheres to the surface. This process is also commonly used for structural objects. Thermal-barrier coatings can be applied to exhaust heat-management applications. They are effective in preventing the formation of corrosion on a range of metals.

Adhesion processes depend on the chemical composition of the surface’s top molecular layers. Proper calibration of surface treatments is essential for a predictable adhesion process. Some surface treatments involve using high-tech machines, while others are applied by hand. Different types of surface treatments require different methods and power supply. Different materials exhibit different chemical reactivity and may require different surface activation methods. Some processes are easier to perform in large batches while others require more accurate and consistent treatment.
Metallic coatings are applied by different methods. These treatments can increase the properties of aluminium, including its aesthetic appearance and corrosion resistance. The type of surface treatment used will depend on the application of the material and the desired depth of the surface treatment.
In addition to using plasma to modify surfaces, plasma also helps clean and oxidise organic contaminants. It converts hydrocarbons into carbon dioxide and water vapour. It also activates the surface by replacing inert hydrocarbon bonds with reactive groups. As a result, the surface gains a higher energy level, allowing for improved adhesion and bonding with adhesives. This type of surface treatment is particularly useful for applications where the product must be sterile.
Chemical treatment is a popular option for coatings on various surfaces. This technique creates a thin film of oxide or sulphide on a surface. These treatments are usually used for corrosion protection, metal colouring, and priming painted surfaces. In steel parts, black oxide is a common surface treatment, while “passivation” is used for removing free iron from stainless steel. The result is a high level of corrosion protection.
