Shen, L. (author), Li, S.B. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)The oxidation crack healing of Cr2AlC and Cr2(Al,Si)C was studied and compared with known healing of Ti2AlC. The oxidation induced crack healing of Ti2AlC is relatively fast and leads to full strength recovery, but the oxidation product contains besides ?-Al2O3 also undesired TiO2. However, when oxidizing Cr2AlC only ?-Al2O3 is formed, but full...conference paper 2013

AbdolahZadeh, M. (author), Esteves, A.C.C. (author), Van der Zwaag, S. (author), Garcia Espallargas, S.J. (author)Sol-gel technology is increasingly being used in coatings for corrosion protection and adhesion improvement. So far, the self-healing concept in sol-gel coatings has only been approached from extrinsic healing perspective (i.e. use of nano and micro carriers of corrosion inhibitors) [1]. Despite the benefits of this approach, the damaged area...conference paper 2013

Prajer, M. (author), Wu, X. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)Polymers reinforced with high performance fibres are successfully replacing metal alloys in lightweight aircraft structures. A critical factor in structural design is the resistance of a structure to progressive damage which develops during its service time. The brittle nature of matrix cracking is the main source of composite failure initiating...conference paper 2013

Farle, A.M. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)The reduction of maintenance and replacement work costs is an important driving force in the development of high temperature materials (T>800 °C) that can autonomously heal damage as a result of local cracks. In recent years some potential routes involving the addition of sacrificial particles have been identified, yet these systems have the...conference paper 2013

Bose, R.K. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)Supramolecular rubbers based on 2-aminoethylimidazolidone and fatty acids with epoxy crosslinks have been shown to self-heal via multiple hydrogen bonding sites. In this work, several tools are used to investigate the molecular mechanisms taking place at the interface to understand cohesive healing in these polymers. The quantification of self...conference paper 2013

(author)A long-lasting barrier protection at damaged sites of coated system can be achieved by means of an active response of the primer. This may be attained through the release of reactive liquids from dispersed containers, the increase of the local mobility of the polymeric network, or the expansion of (dispersed elements in) the primer [1]. Such...conference paper 2013

(author)The role of deformation-induced defects and carbon addition on the copper precipitation during aging at 550 oC is investigated in high-purity Fe-Cu-B-N-C alloy samples by Coincidence Doppler Broadening. In samples with 0% and 8% cold pre-strain, the influence of tensile pre-deformation on the precipitation kinetics of copper is studied. The...journal article 2013

Van den Ende, D.A. (author), Fischer, H.R. (author), Groen, W.A. (author), Van der Zwaag, S. (author)The meso-scale surface roughness of piezoelectric fiber composites can be manipulated by applying an electric field to a piezocomposite with a polished surface. In the absence of an applied voltage, the tips of the embedded piezoelectric ceramic fibers are below the surface of the piezocomposite and a silicon wafer counter surface rests solely...journal article 2013
