The adhesion of thin CVD films on polyolefins is often critical due to the low surface free energy of the polymers. In this study, injection moulded PP samples are produced and investigated. The samples are treated in very well-characterized pulsed plasmas before a HMDSO-based coating is applied. The resulting bond strength is analyzed using pull-off tests. The fractured interfaces are characterized with XPS. Oxygen and argon plasma pre-treatments of the PP samples result in a bond strength improvement by a factor of about 2. Comparing oxygen and argon pre-treatments at equal ion fluences to the surface, it can be shown that the bond strength between CVD-coating and polymer is similar.

“…The applicability for a large substrate area and the absence of electrode degradation or pollution makes them attractive for a variety of purposes. A computational investigation of these plasmas with a feeding gas of either argon or oxygen is the main objective of this study with a focus on a coaxial plasmaline [1][2][3] used in the processing of the PET bottles. Considered operation conditions cover a pressure range of 25 − 8000 Pa in cylindrical (surfatron) or coaxial (plasmaline) structures with either continuous or pulse-modulated power input.…”

A volume-averaged global model is developed to investigate surface-wave discharges inside either cylindrical or coaxial structures. The neutral and ion wall flux is self-consistently estimated based on a simplified analytical description both for electropositive and electronegative plasmas. The simulation results are compared with experimental data from various discharge setups of either argon or oxygen, measured or obtained from literature, for a continuous and a pulse-modulated power input. A good agreement is observed between the simulations and the measurements. The calculations show that the wall flux often substantially contributes to the net loss rates of the individual species.

“…In this way, HPPMS simplifies coating deposition on complex geometries [22][23][24][25][26]. In addition to that, plasma-based deposition of coating layers has considerable ecological and economic advantages [27,28]. To increase the life time of the coatings, the investigation of their fracture behavior is a crucial point which was discussed by several authors [29][30][31][32].…”

Cohesize zone‐based modeling of nano‐coating layers for the purpose of establishing process signatures

et al. 2017

View full text Add to dashboard Cite

The purpose of this work is to establish the notion of process signatures in the context of manufacture processing. In this context we provide an overview of selected computational approaches which are capable of resolving the basic features of non-linear heterogeneous microstructures and process related boundary and loading conditions. As an example, the cohesize zone element method is employed to predict the state of damage and fracture in coated systems. The latter are composed of CrN-or AlN-based protective coating layers and steel-based substrates. The state of damage and fracture is simulated for nano-indentation tests and discussed at different deformation stages. Furthermore, the influence of residual stresses within the polygrain microstructure on the evolution of damage and fracture is analyzed. Lastly, future developments and computational challenges are discussed.
