Full textThe interface between titanium Ti-3Al-2,5V and Polyetheretherketone (PEEK) in Ti-CF/PEEK laminates are investigated. Comparative investigations of mechanical, chemical, chemo-physical and physical surface pre-treatments evidenced that surface pre-treatment by a pulsed Nd:YAG laser (physical pre-treatment) offers both good adhesion and superior moisture resistance of the titanium-PEEK interface. The titanium-PEEK interface modified by laser pre-treatment is characterized mechanically and analytical in detail. This investigation takes into account all process steps (surface pre-treatment, bonding, and ageing) as well as all the phases and interfaces in the titanium-PEEK system (i.e. titanium, oxide, and also PEEK). The delamination behavior is investigated mechanically with the mixed mode bending experiment (MMB). The MMB loading was represented by a superposition of simple mode I and mode II loadings. Based on MMB fracture surface analysis, a failure and damaging mechanism could be assumed. The analytical methods used in this investigation are a cryo-fracture, X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX), secondary electron microscopy (SEM, EDX, transmission electron microscopy (TEM), analytical TEM (EDX, EFTEM, EELS), adsorption/desorption experiments (Krypton-BET), Laser scanning microscopy (LSM), contact angle measurements, and Raman microscopy. The adhesion and degradation mechanism observed at the titanium-PEEK interface strongly depends on the applied surface pre-treatment. The interface properties between pretreated Ti-3Al-2.5V and PEEK show an influence of the morphology of PEEK. For the first time, interfacial crystallization of PEEK at the Ti-3Al-2.5V surface was confirmed by experimental results. Interfacial crystallization is known for its strengthening effect perpendicular to C-fibers within CF/PEEK laminates and implies a strong interaction between PEEK and the oxide layer on the Ti-3Al-2.5V joining partner. Moreover, the investigations of the interface between laser treated Ti-3Al-2.5V and PEEK indicate that adhesion is not only due to mechanical interlocking on micro- and nano-scale. Chemical interactions between the polymer and the joining surface seem be promoted byan increased surface reactivity due to the high surface area structures on micro- and nano-scale. In addition, an aluminum-enrichment was detected with TEM at the treated surface that may play a role in the bonding. During the cooling phase of the consolidation of the thermoplastic, thermal stress arise at the interface due to suppressed expansion and contraction of the individual components. It can be assumed that PEEK, which is interlocked within the oxide pores, reduces the stress by relaxation processes. Relaxation induced re-orientation of the molecule structure is able strengthen the interface as it is known from self-reinforced polymers. This assumption could explain the interface behavior characterized by mode I and mode II loadings. High energy release rates observed at mode I loadings could be traced back to the re-orientated molecule structure which is equal to the direction of mode I loading. This mechanism is material specific and can be applied only to cure-free thermoplastics. The long-term durability is enhanced significantly when of surface structures on nano-scale are formed by the pretreatment. This result is in good agreement with the literature. However, during the bonding process not only on the formation of adhesion between PEEK and Ti-3Al-2.5V is important but also the stability of the interfacial phases within the Ti-PEEK interfacial system as shown on the interface properties between anodized Ti-3Al-2.5V. Anodized oxide phases, for example, which degrade during the bonding by oxidation diffusion, were found to result in low interfacial strength and low long-term durability. Aging in hydro-thermal environment are enhanced by further factors. Residual stress which arises during the bonding process leads to cracks within the oxide and within martensitic region. Entrapped air which especially develop when large areas are bonded enhance water diffusion along the interface and hydrothermal aging. A basic understanding of the titanium-PEEK system requires that all phases and interfaces in the titanium-PEEK system as well as all process steps are taken into account. Although the polymer will be neglected in most cases this investigation reveals that even the polymer morphology significantly influences the interface properties.

Full textEllipsometric light scattering is introduced as a new and powerful technique to characterize layers on colloidal particles. For the experiments, the polarization optics used reflection ellipsometry was installed in the beam of a light scattering setup. Using the priciples of null ellipsometry, a small range of scattering angles is obtained, were the method is sensitive to layers on the surface of colloidal particles. This is an analogy to the layer sensitivity of reflection ellipsometry at planer interfaces close to the Brewster angle. The theoretical basis for ellipsometric scattering is the Mie theory with its modern supplements. The feasibility of characterizing layers on colloidal particles was demonstrated with several systems. First, layer thickness and layer refractive index of poly(N-isopropylacrylamide) layers on a poly(methylmethacrylate) core were determined. This was the first time that the refractive index and with that the degree of swelling of a layer was directly determined in an scattering experiment. Second, polyelectrolyte layers on Poly(methylmethacrylate)-Poly(styrenesulfonate)-blockcopolymer particles were characterized. The influence of the salt concentration on the parameters of the layer was determined. The results show that the polyelectrolyte chains in the system investigated are not streched. Third, layers of ions around electrostatically-stabilized poly(styrene) particles were characterized. The layer thickness and layer refractive index in these examples are shown to be much larger than predicted by the classical Poisson-Boltzmann-theory. In addition, the birefringence of lipid vesicles was determined. Another interesting application of the ellipsometric scattering is the dynamic light scattering with ellipsometric optics. Its results show a characteristic process with a correlation time independent of the scattering vector, but wavelength dependent. The origin of this mode is not yet completely clarified.
