The main factors characterizing the uncertainty of the measuring situation during thermophysical measurements are considered. An approach is proposed for determining the parameters of the thermophysical properties of materials and the measurement error under uncertainty. A conceptual model of the formation of a measuring environment for an intelligent information-measuring system of thermophysical properties of materials in a situation of uncertainty has been created. The solution of the optimization problem of identification of the measuring situation when determining the thermophysical properties of solid materials of various ranges of thermal conductivity is presented. An information model has been developed to identify a measurement situation in an intelligent information and measurement system operating under conditions of uncertainty.

The analysis of properties of thermosensitive elements used in devices for monitoring the temperature and thermophysical properties of the medium and materials is carried out. Thermal converters made of various materials are considered: metals, semiconductors, oxides. The sensitivity to infrared radiation of the considered elements is analyzed. The range of measured temperatures and the linearity of the output characteristics of the converters are investigated. A conclusion is made about the purposefulness of using one or another type of thermosensitive elements.

New data for thermophysical properties of materials are being discovered and measured routinely throughout the world, but sometimes conflicts exist in the published data from various sources. We introduce an online thermal properties database intended for use as a repository for experimentally obtained thermophysical properties of materials by researchers across the globe. This online database is a part of www.thermalhub.org, which is a NSF-funded cyber infrastructure initiative aimed at serving the global heat transfer community. The relevant details associated with an experiment, such as the material type and composition, the thermophysical property measured, the test methods employed, the test conditions of the experiment, the results of the experiments, the uncertainty associated with the experimental results, and the literature where the results are published, are included as fields in the online database. It is known that one thermophysical property can be tested by various methods whose results may differ. Similarly, one thermophysical property can be experimentally measured under varying test conditions to produce different results.

AbstractIncreasing demands on production processes in terms of performance, reliability and environmental compatibility shape the specification profile for modem wear resistant coating systems. The specification of PVD coated cutting tools by the parameters hardness, wear and frictional behavior, chemical structure or chemical resistance are already known and inspected by small scale tests, e.g. pin on disc or taber abraser test. Hitherto the thermophysical properties of thin film PVD coatings were not characterized completely although the investigation of the thermal diffusivity of coated substrates give information about the thermal barrier function of the deposited coating.To determine the thermophysical properties of PVD coatings the Jenoptik Thermal Wave Inspection (TWIN) can be used. This nondestructive and contactless measuring system is based on the photothermal spectroscopy. In this paper fundamentals of the TWIN measuring technique are presented as well as first TWIN results of investigated MSIP TiN and TiAlN coated and oxidized high speed steels.
