The Scientific and Technological Council

One of A3TS's main missions is to promote the scientific aspects of the heat treatment and surface treatment industries. This involves disseminating information via various media (press, internet) and organizing technical days and conferences.

The Scientific and Technological Council ensures the quality of the information disseminated by the A3TS. Composed of about twenty members and animated by its President, the Scientific and Technological Council exercises a mission of proposal by generating ideas and by ensuring the renewal of the themes.
Representative of the diversity of the actors and the sectors, it claims a strong anchoring in the reality of the profession as well as in innovation through research.

It is the guarantor of the scientific quality of the information disseminated by the A3TS, and also has a mission of monitoring and control over the content of conferences and articles.

Technical Commissions led by the Scientific Committee

The technical commissions are the "kingpins of the A3TS", they federate the skills of its members to promote the technical and technological developments of the moment.
Thus, within the framework of their work, the commissions contribute to making the capitalized knowledge available to the companies concerned. In addition, the expertise induced by this work in the field of heat treatment is widely disseminated to industries where these technologies are essential in the design and manufacture of products, components, mechanical equipment...

 

Generally the dissemination of the work of the commissions is carried out in four forms:

  • Writing articles in specialized magazines

  • Participation in technical days, seminars, conferences...

  • Realization of training courses specific to the field

  • Writing and publishing of specialized books

TREMPLE FLUID Commission: facilitator Alexandre FLEURENTIN

The "quenching fluids and systems of today and tomorrow" committee, led by Alexandre FLEURENTIN (Métallo Corner), meets three times a year and brings together a wide range of industrial users and formulators of quenching fluids (gas, polymer, oils, salt baths). These days, rich in exchanges, are the right time to tackle the following projects:

Standardization of the "infrared" method to measure the ageing of a quenching oil: Led by Odile ALLEAUME (Fuchs), this working group's mission is to propose a draft standard to measure the level of oxidation and cracking of a quenching oil in service. Circular tests in about ten laboratories are underway to complete this project.

Control and design of gas, oil, water/polymer and salt quenching tanks: At each meeting, we decided to invite a manufacturer of industrial furnaces to discuss the safety and design of quenching installations. We would like to thank the companies we have already met (ECM, ALD, SECO WARWICK, PETROFER, SAFED to follow) for the constructive exchanges we have had on this subject.

Development of sensors for drasticimeters: A problem was raised within the working group regarding the availability of this type of sensor, which is produced "outside our borders" by only two suppliers. This configuration can be a source of problems in terms of supply. A sub-group was formed around Eric FRADET (Synergy Consult) in order to remedy this situation.

Update of the book of the 90s on "quenching fluids and systems": The members of the commission decided to update a book of the 90s on quenching fluids, it was time... We are currently working on different topics: standardization and specifications, oil quenching, polymer / water quenching, gas quenching, press quenching, salt bath quenching, cryogenic cooling, but also defects and remedies associated with the various technologies.

Approach of the strain dispersion in different quenching chambers: this new project aims at studying the impact of the quenching fluid but also of the dimensioning of the quenching cell on the strain dispersion, by analyzing the response of specimen coupons placed in different heat treatment facilities.

ALUMINIUM & STEEL surface treatment commission: facilitator Frédéric RAULIN

One of the objectives of the commission is an exchange of industrial, technical or scientific information between its members, which is concretized at each meeting by an important part in the agenda.

Another objective is to intervene in training establishments: Universities, professional high schools, IUT, engineering schools. It has been noted that surface treatments of light alloys are absent, or only briefly mentioned, in the curriculum of these establishments. It was therefore necessary to prepare an adapted training, intended to present:
* the heat treatments of light alloys
* the main treatments carried out on Al and Ti (chemical and electrolytic conversions)
* the safety, environment and quality issues
* the surface treatment professions

In 2014, a day was organized, on February 12, at the ENI in Tarbes with the participation of students from the Lycée Professionnel Jean Dupuy, a day that proved to be particularly rich and full of questions from the students. A second day was organized on October 14, at the Lycée MERMOZ in Saint Louis, with the participation of 70 people, and the honors of an article in the Dernières Nouvelles d'Alsace!

The third objective is to list and make known to the members of the association and more widely to the users of aluminium, the usable surface treatments and their characteristics, as well as their state of development, industrial or R&D. This information is made available in the form of electronic sheets available on the association's website:
. These sheets are short, A4 format, and simple. The target is a non-specialized public. The treatments described range from the most commonly used to the least known, from those that have been industrialized for many years to those that are under development.

This year has seen the revision of sheets on chromium anodizing, coloring, hexavalent chromium-free chemical conversions and surface treatment standards, and new sheets on TSA, painting technologies and pre-paint treatments.

The last objective is the organization of technical presentations, in front of the commission, by formulators, laboratories or organizations, on novelties interesting the profession. These presentations are then reported in "A3TS Sciences et Techniques".

Wear and tear commission: facilitator yVES gachon

Improving wear resistance and optimizing friction properties are the goals of many surface treatments and heat treatments. This is an essential concern for design offices and a way to progress in mechanics, automotive, aeronautics, energy ... A number of conventional solutions are then questioned. It is therefore necessary to look for sustainable solutions with respect to future regulations and to evaluate them from a tribological point of view. This evaluation requires tests, which are not standardized enough, making it difficult to compare each solution. It is therefore essential to have a range of tests covering a wide range of applications.

In order to reduce development time and to validate the integration of tribological parameters earlier in the design process, it is necessary to have a tool for modeling the mechanics of contacts.

Before being able to provide solutions to all these problems, it is important to take stock of what has already been achieved and to lay the foundations of the technique.

For this purpose, the Commission has set itself several objectives which will be, in the first instance, the drafting of documents in the form of a collection, review or technical bulletin:

  • To provide the industry with sources of information and expertise on the subject of "Friction - Wear".

  • List the different tests characterizing friction and wear

  • To extract combinations of tribological functionalities (friction, wear) from sensitive components and key positions in the aeronautics, automotive and energy sectors

  • Establish a matrix of the different solutions applied to meet these functionalities

  • Propose simple test methods to control the drift of the different production phases with respect to the tribological performance of coatings

to propose at regular intervals an event of restitution of the work and exchange with the community. (conference, publication...)
