Abstract
The paper gives a description of producing a resistance heating element from multilayer coatings, which were deposited on a steel base by the method of microplasma spraying. TiO2 in the form of powder with particles of 15–40 mm size was used to deposit narrow resistive paths. A sublayer from Al2O3 with 40 mm particle size was deposited to provide electrical insulation from the steel base. Performed testing of resistance heating elements showed their serviceability up to the temperature of 200 ºC at specific power of 75 W. Increase of heating temperature of resistance heating element in air above 230 ºC leads to loss of electrical conductivity. The main possible areas for such resistance heating element application are mechanical engineering, chemical and radioelectronic industries. Performed experiment allowed demonstrating the fundamental possibility of manufacturing resistance heating elements with resistive paths from TiO2 with application of microplasma spraying technology. 18 Ref., 1 Table, 5 Figures.
