Nowadays, a significant problem of high powered two-stroke engines is burning-through of the piston. This problem can be solved by the thermal barrier coatings. It is formed by the method of microarc oxidation (MAO). In this work it was proved that MAO coating of the piston bottom increases the burning-through resistance of two-stroke internal combustion engines. The influence of MAO-layer on the two-stroke engine characteristics (torque, brake specific fuel consumption, temperature under the spark plug and emissions) are investigated. As result, in case of MAO coating of the piston bottom 2.4 times reducing of the burning-through likelihood is take place. Negative impacts on the engine parameters (brake characteristics or emissions) are not detected.
