The computer model that allows predicting the temperature distribution during local ion nitriding with hollow cathode effect (HCE) and depth of the diffusion zone after the treatment was developed. The influence of the HCE on the temperature distribution for the gear was studied. Investigation results of the hollow cathode effect influence on the hardened layer depth for a sample of 38KhMYuA steel are presented.

The actual problem of accelerating and reducing the energy costs of the foam concrete slabs heat treatment technological process is considered. It is shown that to solve this problem, it is advisable to use the microwave radiation energy as a heat source. The main advantages of the microwave method of foam concrete slabs heat treatment in comparison with traditional methods are considered. The design of a microwave installation for the foam concrete slabs heat treatment has been developed. The installed microwave radiation sources have energy outputs in the form of a rectangular waveguide openings, which are used as radiating antennas. Huygens-Kirchhoff method was used to calculate the temperature distribution on the foam concrete slab surface; the method of loaded long lines was used to calculate the temperature distribution over the foam concrete slab thickness. A method for measuring the foam concrete slab temperature distribution is proposed. The results of theoretical and experimental temperature distribution studies on the surface and the cross-section of foam concrete slab with a width of 1500 mm, a height of 1000 mm and a thickness of 200 mm, a density of 1000 kg/m3 on the electromagnetic fields oscillation frequency of 2450 MHz are shown. The obtained experimental results showed a high efficiency of using microwave radiation for the foam concrete slabs heat treatment technological processes. Microwave technologies can be used for heat treatment of products made of concrete, reinforced concrete and polymer composite materials.

This paper deals with the theory and application of microwave radiation and experimental optimization of microwave radiation for the distribution of temperature field in the irradiated wooden elements. The article describes the experimental work performed at the Faculty of Civil Engineering, in close cooperation with the company S. P. UNI, s.r.o.. Analysis of the research results was to determine the optimal intensity of microwave emitters and the necessary length of exposure to moist building materials microwave radiation with respect to a particular type of a wooden element. A part of the research was divided into several separate experiments. In each experiment the heating under various conditions was carried out on: I.- samples of the same size, but different weight moisture content, irradiated in the same time periods, II.- samples of the same size, same weight moisture content, irradiated for different time periods.

This paper describes the development of computer model used to characterize the heat transfer properties of the laser sealed advanced zirconia based ceramic coating. The model is built using ANSYS (11) software where all the environments simulated to be similar to the experimental environments. According to experiments dealed with the same data the temperature cant be reading since it is difficult to be fast enough as the changes occurs due to small interaction time .The temperature profile was recorded with each traverse velocity, the temperature changes with time and velocity were recorded too.
