The SPTCS

Presentation of the laboratory

The purpose of the S.P.C.T.S. works (Science laboratory for ceramic processes and surface treatements) is to study the transformations of material that occur in the implementation of ceramic processes and surface treatment processes.

These activities are at the intersection of the «materials» field and the field of «processes», and the SPCTS concentrates its effort on certain specific fields, such as those relating to the shaping of ceramics, to processes of thin or thick layers deposit, most of them ceramic, and to functional materials and their properties of use.

Its objective is to understand, characterise, control, and, if possible, model the various processes which lead to obtaining an object with one or more properties for a given use. It thus occupies an original place in French research, which gives it a reputation that is recognised at national and international level.

What is more, the scientific knowledge acquired provides effective support for companies which use ceramic processes, in particular in energy production, electronics, optoelectronics and bio medical fields (Liquid air, Snecma, Alcan, Areva…).

The areas of research

The S.P.C.T.S. (Ceramic Processes and Surface Treatment Sciences) offers three main lines of activities :

1) ceramic processes

2) surface treatment processes

3) multi-level organisation of materials

The GEMH

Presentation of the laboratory

Le The Heterogeneous Materials Study Group (G.E.M.H.) consists of 27 teacher-researchers. It is divided into 2 teams :

- The aim of the “Mass distribution mineral materials” team, based in Limoges, is to study the mechanisms governing the development and evolution of properties of very heterogeneous materials under the effect of the constraints of use.

- The “Civil Engineering and Durability” team, based in Egletons, studies the problems of durability and ageing of materials and structures. Experimental approaches and modelling are carried out jointly. The effects of mechanical and environmental load are treated in an uncoupled to coupled way.

The GEMH (Heterogeneous Materials Study Group)

The areas of research

Main lines of research of the “Mass distribution mineral materials” team :

1. Cold consolidation of materials: reaction mechanism and development of new processes ;

2. Development of ceramics: processes and microstructure :

- Control of the microstructure of products derived from natural raw materials,

- Thermal aspects of the processes,

3. The mechanical and thermal behaviour of heterogeneous material: characterisation and simulation

The products concerned are mass distribution materials, generally containing silico – aluminous minerals, such as :

- massive refractories, cements, natural mineral raw materials and their ceramic derivatives, silicate ceramics, enamels, composites, porous materials, coatings.

Main lines of research of the “Civil Engineering and Durability” team :

1. Durability of roadways: diagnoses, behaviour under load, material fatigue, thermo mechanical couplings, mechanics of interfaces

2. Wood-construction: creep behaviour, hygro-mechanical couplings, assemblies of structures under load, thermo-hydric behaviour of wood envelopes.
