Applications

Treatment of materials & alloys

Stainless steel, titanium, aluminum, additive manufacturing: adapt the treatment to the material, its surface condition, and its manufacturing method.

The material is a starting point. Grade, initial condition, manufacturing process, assemblies, geometry, and function together determine the surface treatment suited to your part.

The Challenges

A strategy tailored to the material

Identifying the grade

Taking into account the actual material present, its composition, and its manufacturing method.

Understanding the surface

Examining its condition, roughness, topography, and any alterations or contamination.

Ensure compatibility

Selecting the process and chemistry compatible with the material and the desired result.

Your Need

Different materials, different challenges

Technochim develops and implements mechanical, chemical, and electrochemical treatments tailored to materials and their applications, from stainless steels used in pharmaceutical environments to alloys and surfaces resulting from more specific manufacturing processes.

Stainless steel
Stainless steels represent a major area of Technochim's expertise. 316L, as well as other stainless steel grades, may require different strategies depending on their manufacturing, surface condition, and operating environment.
In the pharma and biotech sectors, 316L is particularly prevalent in tanks, piping, clean fluid loops, and process equipment.
Titanium
Titanium surfaces require an approach that takes into account the grade, initial condition, and desired outcome, whether for preparation, finishing, or protection.
Aluminum
Treating aluminum must factor in the specific characteristics of the material and its alloys. Cleaning, preparation or protection options are assessed according to the application and surface condition.
Additive manufacturing
Additive manufacturing does not refer to a single material. It produces parts in different alloy families with specific surface conditions and geometries.
Technochim studies how to adapt surface treatments to these new configurations, particularly when geometric complexity or the surface condition resulting from manufacturing calls for a specific approach.

Our Approach

The material alone does not define the treatment

Two parts made from the same alloy may require different strategies depending on their manufacturing, surface condition, geometry, and function.

Identifying the material

Gathering the grade, manufacturing process, assemblies, and available history.

Characterize the surface

Examining the initial condition, roughness, topography, deposits, or any alterations.

Assess Feasibility

Defining the process, chemistry, and, where necessary, compatibility testing.

Treat & characterize

Carrying out the treatment and verifying the defined surface characteristics.

Understanding materials

Focus — Stainless steel & critical environments

Stainless steel plays a central role in pharmaceutical, biotech, and high-purity environments, notably for its corrosion resistance properties and its suitability for integration into process equipment and installations.

Adapting the strategy to stainless steel grades

Technochim works with 316L and various stainless steel grades, adapting the strategy to the actual condition of the surface and its intended use.

Depending on the issue at hand, this strategy may combine degreasing, pickling, passivation, derouging, descaling, mechanical polishing, electropolishing, or other surface preparation and restoration operations.

Focus — Additive manufacturing

Additive manufacturing processes open up new design possibilities, but also generate specific geometries and surface conditions.

The post-treatment strategy must therefore take into account the alloy, the manufacturing process, the initial topography, and the desired final characteristics.

Technochim is building its expertise in this field with dedicated additive manufacturing testing facilities and the study of treatments suited to these new surfaces.

Technochim Expertise

One material, one surface, one strategy

Technochim combines material knowledge, surface characterization, and mastery of mechanical, chemical, and electrochemical processes to determine the strategy suited to each application.

The choice of treatment is therefore never based on the material name alone, but on the combination of material + surface condition + manufacturing + desired function.

What strategy suits your material?

Specify the grade, manufacturing method, assemblies, surface condition, and desired function. Drawings, photographs, and available data will help us prepare the study for the appropriate treatment.
