This article reviewed the methods that are available to test thermal properties of various insulating materials. These methods can fall under one of two categories: steady state techniques and non-steady (transient) techniques. The transient plane source (TPS) method is classified as a non-steady state technique. The TPS sensor is a round piece of engraved nickel that conducts electrical currents and is covered with a coating of Kapton, Mica or Teflon. To measure thermal conductivity and thermal diffusivity, the sensor is sandwiched between two identical samples, and it heats the sample in every direction while measuring the temperature increase over time. TSP methods are popular because they are quick, and they provide accurate measurements from 0.005 to 500 W/mK for temperatures between 30 and 1200 K. Another advantage of hot disks is that they can test smaller samples than other methods because the size of the sensors can be changed depending on the sample.
Composite spray coatings containing Al2O3 and AlN were prepared and their tensile bonding strength, microhardness, corrosion behavior and thermal conductivity were compared to those of pure Al2O3. The goal of this study was to identify a spray coating with an improved thermal conductivity over that of Al2O3 for use in coating heat exchangers, furnace walls, heat pipes, etc. The coatings that were prepared had AlN : a-Al2O3 ratios of 4:6 and 6:4. It was determined that the thermal conductivity of the spray coatings increased with increasing AlN content, as did the coatings’ resistance to corrosion; however, the microhardness and tensile bonding strength were decreased by the addition of AlN.
