Definitions
- titanium in the aerospace industry has increased over the past 30 years, which accounts for up to 15% of the structural weight in the latest generation of aircraft (e.g. Airbus 350 XWB, Boeing 787).
- the reasons for the increase could be due to the need to replace aluminum structures at connection points between composite materials and metal structures due to problems due to galvanic corrosion.
- the corrosion resistance and the strength-to-weight ratio of titanium and its alloys make it interesting for new design concepts. Titanium materials show problems with long-term stable adhesion. Rivet rash on titanium rivet heads, loss of color on crack flaps or delamination of fiber metal laminates are some examples of this problem.
- the surface treatment is the most important step to ensure permanent connections.
- developed for the surface modification of titanium In order to increase the durability, developed for the surface modification of titanium.
- Mechanical surface treatments such as sandblasting are mainly used to create a macroscopically rough surface and to remove residues.
- CAA leads to a high bond resistance.
- alkaline electrolytes are being discussed as a pretreatment for the structural bonding of titanium.
- electrolyte based on sodium hydride porous oxide layers on titanium could be created.
- Sodium hydroxide anodization can ensure a good durability of adhesive bonds in moisture and stress.
- DE 3427543 discloses the use of electrolytes with sodium hydroxide with complexing agents such as ethylenediaminetetraacetic acid (EDTA) in order to increase the rate of dissolution. This NaTESi process enables a highly porous oxide layer and good long-term durability to be achieved.
- EDTA ethylenediaminetetraacetic acid
- DE10201 1 106764B4 discloses an anodizing process based on sodium hydroxide, methylglycinediacetic acid and disodium tartrate dihydrate and pentasodium phosphate.
- sol-gel processes the Rocatec process, pyrosil treatment.
- the prior art lacks a process that can ensure long-term stable adhesion to titanium without using an energy source such as a laser or an electrical field or chemical components that do not comply with the regulations on a permanent basis.
- Anodizing procedures are limited in application. Due to the physics (Faraday effect), they cannot be used in pipes, cavities or channels without additional effort. Shadow effects could also lead to a non-homogeneous oxide layer development.
- the anodization parameters often have to be adapted for each titanium alloy used.
- a laser also includes a surface melting process that creates a heat affected zone with different properties compared to the base material, even for nanosecond pulsed systems.
- the prior art lacks a method which can ensure long-term stable adhesion to titanium without using an energy source such as a laser or an electric field or chemical components which do not comply with the regulations on a permanent basis.
- Surface pretreatment in the sense of the present invention is to be understood as a chemical conversion of oxide layers of the titanium or the titanium alloy. Titanium alloys consist predominantly of titanium, based on atomic%. The NaOH content advantageously does not exceed 590 g / l.

- Contact can be diving, spraying, painting.
- nanostructures with dimensions below 100 nm can be produced and thus mechanical and chemical processes can be realized with an enlarged surface, which improves the durability and adhesion properties on titanium or titanium alloys treated in this way.

- the invention further comprises an aircraft, in particular an aircraft with an article according to the invention made of titanium or titanium alloys.
- the examples show different treatments of different titanium alloys. The conditions are given in each case. Before the treatment, the material samples were washed with isopropanol or with an alkaline degreasing agent (Metaclean T2001, only tests 7 and 8). To the treatment, the material samples were washed with isopropanol or with an alkaline degreasing agent (Metaclean T2001, only tests 7 and 8). To the treatment, the material samples were washed with isopropanol or with an alkaline degreasing agent (Metaclean T2001, only tests 7 and 8).
