In Situ Synthesis of Fe–TiC Nanocomposite Coating on CK45 Steel From Ilmenite Concentrate by Plasma-Spray Method
Journal of Tribology, 2016Co-Authors: Alireza Firouzbakht, Mansour Razavi, Mohammad Reza RahimipourAbstract:These days wear-resistant coatings including Fe–TiC composites because of their properties such as high melting point, hardness, and wear resistance are used in different fields such as Aerospace, Transport, cutting, and abrasive. In situ synthesis of Fe–TiC nanocomposite as a wear-resistant coating by the plasma-spray process is the purpose of this study. Ilmenite concentrate and carbon black were used as raw materials. Three kinds of powders with different conditions were prepared and sprayed on CK45 steel substrates in constant conditions. Microstructure, phase identification, wear resistance, and hardness of coated samples were determined. The results showed that activated sample was synthesized during the plasma spray, but in situ synthesize did not happen for inactive sample which was sprayed by plasma spray. Also, wear resistance and hardness tests showed by synthesis of Fe–TiC composite in coated samples, wear resistance, and hardness were increased.

Investigation of mechanical properties of tufted composites: Influence of tuft length through the thickness reinforcement
Composite Structures, 2017Co-Authors: Lingshan Liu, Peng Wang, Xavier Legrand, Damien SoulatAbstract:Abstract In the Aerospace, Transport and energy industries, laminated composites are widely used to manufacture thicker and more complex composite pieces. Three-dimensional (3D) fabrics have been developed to replace the multilayered reinforcements in some applications to increase performance through the thickness. The present study is dedicated to improving the understanding of the mechanical performances of 3D composite pieces reinforced by tufting. The tufting process and the equipment configuration are described in detail in the present paper. A 3D reinforcement architecture is prepared by the tufting process with varied tuft length, and then resin transfer moulding technology is used to manufacture the composite samples. Tensile tests are carried out to characterise specifically the influence of the tuft length on the tensile performance of tufting threads through the thickness of composites. The tensile results and microscopic analysis on the cross section of the 3D specimens show that the tuft length strongly influences the mechanical properties of tufted composite. Therefore, control of the tuft length is necessary to optimise the tufting process and thus improve the mechanical performance of assembled thick reinforcements and composites.

Sol-Gel Technology for Innovative Fabric Finishing - A Review
Journal of Sol-Gel Science and Technology, 2016Co-Authors: Wan Norfazilah Wan IsmailAbstract:Sol–gel technology continues to interest researchers from both industries and governmental institutions in many parts of the world decades after its discovery. It offers efficient and high-purity production of nanopowders, fibres, solid structures and thin-film coatings. Possible applications of sol–gel technology can be found in a wide range of sectors, such as pharmacy, medicine, construction, Aerospace, Transport, food industry, optics, agriculture, semiconductor devices, catalysis and biotechnology. Also in the textile sector, sol–gel technology is expected to lead the production of fabrics with completely novel properties or the combination of various functions in one fabric. The sol–gel reaction is easy to perform and does not require special conditions and high temperatures. The reaction consists of a series of simple hydrolysis and condensation reactions. This paper presents an overview of sol–gel technology and discusses the fabric functions that can be achieved by the technology.

ISoLA (1) - Thematic track: formal languages and methods for designing and verifying complex embedded systems
Lecture Notes in Computer Science, 2010Co-Authors: Yamine Aït Ameur, Frédéric Boniol, Dominique Méry, Virginie WielsAbstract:Nowadays, it is well accepted that the develop- ment of critical systems involves the use of formal methods. One of the major fields where these methods made a lot of progress are the avionics, Aerospace, Transport areas, telecom, etc. These systems are responsible for various functions, such as navigation, guidance, stability, power management, board/ground communications, passenger entertainment.... Moreover, their complexity is continuously growing.
