Analytical development for the chemical industry and surface treatment

Your need: to carry out an analytical development of surface treatment

Allowing to modify the physical and chemical surface properties, the surface treatments confer to the materials an aspect and particular characteristics.

Depending on the nature of the surface treatment but also that of the substrate which will receive this coating, the various processes of obtaining differ by the technique to be used. We can distinguish in particular :

  • Surface treatments obtained by wet process: electrolytic deposit, chemical deposit, deposit by immersion in a molten metal, …
  • Surface treatments obtained by dry process : spraying, reloading, chemical vapor deposition CVD, physical vapor deposition PVD, …
  • Surface treatments obtained by conversion : anodic oxidation, phosphating, sulfurization, …

In all cases, a high degree of surface preparation is necessary in order to obtain the expected properties of the surface treatment in an optimal way.

In the case of electroplating, the prepared parts are then immersed in baths which, by applying an electric current, produce a metallic deposit on their surfaces. The quality of the deposit thus obtained depends in particular on the chemical composition of the bath, which requires continuous monitoring of its evolution in order to ensure the control of the surface treatment process. These controls and tests require the development of specific analytical methods validated according to adapted references (AFNOR, ICH, VICH…).

Surface treatment refers to a range of techniques used to modify the properties of a material's surface, usually with the aim of improving its performance or appearance. In the chemical industry, surface treatment is used for a wide range of applications, including corrosion resistance, wear protection, adhesion, lubrication and decoration.

Surface treatments can be carried out by a variety of methods such as electroplating, phosphating, anodising, chemical conversion, vacuum spraying, sputtering, electrolytic coating...

The choice of surface treatment method will depend on the properties of the base material and the requirements of the final application. For example, some surface treatments may be more suitable for metals, while others may be more appropriate for plastics or ceramics. In order to determine the ideal surface treatment and process for its application, it is recommended to develop a specific analytical method.

In general, the main purpose of surface treatment in the chemical industry is to improve the quality and durability of the end products or to meet certain regulatory requirements.

In the chemical industry, an analytical method is a procedure or protocol for measuring and analysing the physicochemical properties of a sample. Analytical methods can be developed to characterise raw materials, intermediates and finished products, and to monitor and control production processes.

Analytical methods are used in many areas of the chemical industry, such as pharmaceuticals, speciality chemicals, polymer manufacturing or metal and alloy production. They are essential for ensuring product quality, improving production processes and ensuring compliance with industry standards.

They can be developed in-house by the company itself or by a service provider laboratory such as FILAB. Analytical methods must be validated according to appropriate standards (AFNOR, ICH, VICH, etc.) and their performance must be regularly monitored to ensure their reliability and accuracy.

In the context of a surface treatment process, the development of a turnkey analytical method is particularly important because the quality of the resulting deposit depends on the chemical composition of the bath.

The composition must be continuously monitored to ensure the control of the surface treatment process. This requires regular monitoring and testing, which in turn requires the development of an analytical method specific to the chemical industry. This approach guarantees :

accurate and reliable results
compliance with industry standards.

By using Filab, companies can benefit from the expertise and experience of qualified professionals to develop effective analytical methods that meet the specific needs of their surface treatment process.
