Functional treatments: dehydrogenation

In the context of galvanic treatments,that is, all those industrial processes used to apply metallic coatings to materials in order to improve their surface properties or give them specific characteristics, dehydrogenation is a crucial process.

What dehydrogenation is used for and why it is important in galvanic processes

Dehydrogenation has the task of removing hydrogen absorbed during galvanic processes. If this hydrogen is not removed, it can cause stresses, microfractures and damage in the crystalline structure of the material. This process is crucial to ensure that treated objects maintain their integrity and strength over time, especially when subjected to stress during normal use.

How dehydrogenation occurs

When metal is deposited in electrolyte solutions, hydrogen is also released, which can be absorbed by the base material. This hydrogen can cause structural problems over time. Therefore, dehydrogenation is necessary to effectively remove the absorbed hydrogen, and this is done through heat treatment within a short period after galvanic treatment.

Speaking of ferrous materials, such as steel, they are particularly susceptible to dehydrogenation. This post-galvanization heat treatment is vital to ensure that the steel maintains its strength and structural integrity over the long term.

Exploring dehydrogenation’s practical uses

Dehydrogenation, a sophisticated process, reveals its potential in different situations. Through the use of catalysts, this advanced technique can selectively remove hydrogen from specific molecules, opening up new avenues in organic synthesis. Let’s find out some fascinating details of its practical uses:

● Dehydrogenation of Oxidation: Preserving the robustness of materials.

After materials have undergone the oxidation process, dehydrogenation becomes vital. Its job is to remove any hydrogen that may have been absorbed, preventing the formation of microcracks and ensuring that the structure of the material remains intact over time.

● Dehydrogenation of Alkanes: Molecular Versatility for New Perspectives.

In the vastness of organic synthesis, the dehydrogenation of alkanes presents itself as a magic key. This process makes it possible to produce molecules with higher unsaturation, offering structural flexibility that opens up new design perspectives for chemical compounds.

● Dehydrogenation of Alcohols: What is obtained by dehydrogenation of alcohols.

A common practice in organic synthesis, dehydrogenation of alcohols is a true transformation artist. It removes hydrogen atoms from alcohols, transforming them into compounds with higher unsaturation such as alkenes or ketones. This process is fundamental to the creation of specific chemical compounds, thus contributing to diversity and specialization in chemistry.

● Catalytic Dehydrogenation: An advanced chemical process.

Catalytic dehydrogenation is a sophisticated process that uses catalysts to selectively remove hydrogen from specific molecules. This process has wide applications in organic synthesis, enabling controlled and selective dehydrogenation reactions.

What are the advantages of dehydrogenation in the electroplating industry

Benefits of dehydrogenation in the electroplating industry include the prevention of microcracks and structural damage caused by hydrogen absorbed during electroplating processes. This ensures the durability and strength of treated objects, contributing to their reliability over time.

Which ferrous materials are most susceptible to dehydrogenation

In general, ferrous materials such as steel are more susceptible to dehydrogenation. However,
the extent of susceptibility depends on various factors
, including the specific details of the material and the electroplating process.

Dehydrogenation in Different Contexts: Steel, Screws, Nickel and Galvanizing

● Dehydrogenation of Steel: Protect the strength with heat treatment.

In the electroplating process, dehydrogenation of steel is critical to prevent structural damage caused by hydrogen absorbed during deposition. After electroplating, a targeted heat treatment removes excess hydrogen, ensuring the material’s fatigue resistance over time.

● Dehydrogenation of Screws: Ensuring structural soundness and strength

When it comes to vines, dehydrogenation is a crucial step. This essential process ensures that screws maintain their structural integrity, preventing microfractures that could compromise their effectiveness. A necessary precaution to ensure the strength and durability of the screws.

● Dehydrogenation of Nickel Plating: Critical for a strong and durable surface.

In the case of nickel plating, dehydrogenation is a critical step. It ensures the strength and integrity of the nickel-plated surface, ensuring that the material maintains quality and durability over time. An indispensable step to preserve the surface and ensure high-quality results.

● Dehydrogenation of Galvanizing: Protecting the structure with a key step.

Dehydrogenation in galvanizing is crucial to remove absorbed hydrogen, thus preserving the structural strength of the galvanized object. This process not only prevents microfractures but also protects against trapped hydrogen. A key precaution to ensure robustness and prevent damage over time.

In conclusion, dehydrogenation is a crucial step in electroplating treatments, contributing to the durability and reliability of treated objects.

How does the process take place?

The oxide that is formed is not due to material input but to a transformation of the original surface of the object. The aluminum surface undergoing anodizing is progressively oxidized from the outside of the surface progressing inward. The ‘oxide that is formed has a larger volume than the original metal (aluminum) so that apparently, from a dimensional point of view, it seems away is a material contribution, in reality the thickness of oxide partly “penetrates” into the metal partly “grows” outward. In practice for a thickness of e.g. 10 microns, 5 microns penetrated and 5 microns expanded so the geometric increase amounts to 5 microns. Note that, on a diameter, the 10-micron thickness produces an increase in diameter of 10 microns, not 20.

Oxide also tends to form fairly uniformly in recesses, undercuts, and inside pipes. The structure of the oxide is very similar to the “honeycomb” structure with vertical tubules with respect to the thickness formed. These tubules are much less than a micron in diameter, but particular dyes can penetrate them, being able to impart a wide variety of colorations to the oxide layer. Following the formation of the oxide layer and, eventual staining, a pore-closing operation is performed in order to ensure compactness and corrosion resistance. This operation is called fixing and can be done cold or hot. in any case, the pores are closed; however, it turns out to be safer to heat fix especially for colored oxide layers.
