Introduction
Coating is one of the widely used procedure that involves the application of a functional material in the form of a thin or thick film over a substrate material.
Generally, coating improves wear and corrosion resistance and surface finish of a base material.
Heat energy produced by combustion of coating material.

Interest in zirconia-based ceramics is based on high crack resistance and low setting ability in comparison with most ceramic materials.
Powders of superhard materials and carbon nanotubes are used [8, 9].
Materials and Methods Samples were made in the form of short rods (fingers) with a square section of 5x5 mm and a length of 5 ... 15 mm.
Running-in is one of the important indicators of the tribological properties of materials, during which optimization of the micro geometry and physico-mechanical properties of the surface layers of the contacting materials occurs.
Tribological parameters are influenced by three groups of factors: values that determine the level of external influence on the tribosystem: p - contact pressure, sliding speed, temperature; physical and mechanical properties of materials, of which the most important are the quantities that determine the properties of the surface layers of the contacting materials: elastic modulus E, hardness H, and for brittle materials such as ceramics - stress intensity factor K1c; micro geometry of friction surfaces.

An identification method is used which minimizes the difference
between the measured values and those from a simulated model of heat transfer in the materials.
Introduction The phase change materials (PCMs) are used in microelectronics for the production of non-volatile memory of the new generation.
This assumption is consolidated by the fact that the zone of contact between probe and material is very small and that in addition the characterized materials are more insulating than the cantilever.
