摘要: Abstract Process of plasma electrolytic oxidation (PEO) magnesium alloy MA2-1 in an electrolyte containing sodium hydroxide and tri-polyphosphate was investigated. The use pulse shape polarising current both positive negative semi-periods significantly improved efficiency coating deposition, which is connected with increase number microdischarges on the article surface intensification chemical synthesis processes. Optimal combination interval duration before electric itself appeared to be 6 ms 4 ms, respectively, for pulses 2 ones.
