Designed for laboratory micro‑arc oxidation research tasks, this 15A 750V air‑cooled micro‑arc oxidation single‑pulse rectifier supplies reliable single‑pulse power output to generate ceramic protective coatings on aluminium, magnesium and titanium alloy test samples under bench‑top operating conditions.
15A 750V Air‑Cooled Micro‑Arc Oxidation Single‑Pulse Rectifier fulfils critical power requirements for small‑batch micro‑arc oxidation testing, where consistent single‑pulse output directly impacts coating repeatability and experimental data accuracy. In fact, general‑purpose power supplies cannot deliver sharp pulse edges required for MAO reactions, and they often suffer overheating issues during continuous lab testing cycles. Since micro‑arc oxidation creates instantaneous high‑voltage plasma discharge, efficient air‑cooled heat dissipation becomes essential to maintain stable working temperature and prevent output drift across multiple test runs.
Rated for 15A 750V working specification, this 15A 750V air‑cooled micro‑arc oxidation single‑pulse rectifier adopts compact air‑cooled cooling structure without auxiliary water chiller, which greatly simplifies bench‑top lab deployment. Operators adjust pulse frequency, duty cycle, current and voltage values via local control interface to match different alloy substrates and target coating properties. After equipment wiring and parameter setup, researchers can carry out repeated MAO experiments for small‑size alloy specimens. Meanwhile, multi‑layer electronic protection responds quickly to over‑voltage, over‑current and short‑circuit risks, and this protective mechanism protects both test samples and internal circuit components throughout long‑time experimental operations.
This 15A 750V air‑cooled micro‑arc oxidation single‑pulse rectifier applies high‑speed IGBT switching components, and equipment efficiency remains above 86% under conventional experimental loads. Unlike water‑cooled MAO rectifiers that require supporting circulating water facilities, its air‑cooled layout cuts auxiliary equipment investment, so research teams can launch test work without complex site transformation.
Fast closed‑loop control stabilises pulse output status when ceramic oxide layers grow on alloy surfaces. As a result, processed specimens show smaller coating thickness deviation and fewer surface defects, and researchers can acquire highly comparable experimental data among different test groups. Furthermore, internal memory saves multiple groups of process parameter presets, and users can call verified parameter schemes instantly instead of manually configuring for each new test batch.
Optimised for micro‑arc oxidation laboratory research scenarios, internal control circuits keep pulse fluctuation within a narrow range across full adjustment scope. Therefore, it provides stable driving energy to form uniform, wear‑resistant ceramic coatings for various small‑sized alloy test pieces.
