In this study, the influence of different types of contact materials and their surface roughness, on initiation of a matchhead composition by impact load was analysed using LS-DYNA®.
Recent efforts in lowering contact resistance have led to significantly improved field-effect mobility of OFETs, up to 100 times higher, as the results of careful choice of contact materials and/or chemical treatment of contact electrodes.
Tribocorrosion is the material degradation or transformation of contacting materials resulting from the combined action of wear and corrosion.
We thought that, in point of the effect of the surface topographic feature of contacting materials, there may be some analogy between crawl behavior of the earthworm and the nerve growth of mammal.
Various types of coating systems have been studied to reduce the deleterious effect of volatile chromium species as well as adverse interactions of contacting materials with the ferritic steels.
It is recognised that thermal contact conductance is a function of several parameters, the dominant ones being the type of contacting materials, the macro- and micro-geometry of the contacting surfaces, temperature, the interfacial pressure, the type of lubricant or contaminant and its thickness.
The explanation for this is a relatively small difference between the optical constants of contacting materials.
The method was successfully applied to an extract of food contact material containing over 300 unknown substances.
Thus, the potential for migration of components of food contact materials into foods, and the assessment of exposure and toxicity of any migration is the basis for the safety determinations.
However, because silver is not resistant to an atmosphere containing H2S, SO2 and Cl2, the surface of the silver contact material must be protected.
