Oxide coating

ABSTRACT
The development of modern industry requires the development of high
performance methods for producing coatings on the surface of light constructional
materials. The use of products and structures made of aluminum and its alloys with
high wear resistance, corrosion resistance, prevails in many industries, in particular,
in aircraft industry, shipbuilding, transport engineering.
Currently, a more advanced surface treatment method, a microarc oxidation
method (MAO) is being used to solve this problem. However, when implementation of
a MAO process is carried out using stationary and
is the problem of limiting widespread use of the method. This is due to high power
consumption.
The objective of the study of this work is to study the effect of rapid pulsed effects
of the microarc oxidation process
coating. This mode allows to obtain coatings with high mechanical properties and
reduce power consumption.
Studies were carried out in a pulsed mode with an anodic current pulse duration
of 50–200 μs and a polarizing voltage of up to 300 V. An alkaline electrolyte solution
