Surface Microalloying Of Titanium Alloys In The Manufacture Of Spacecraft Elastic Components

According to technical experts from Russian state research university, JSC NPO LAVOCHKINA and other research institutes, the surface saturation of titanium alloy with oxygen is achieved by forming a stable oxide coating on the electrode surface. MSTU in the course of many years of research work. Bauman of the national research university found that the most technologically advanced method for forming an oxide layer on a filler rod is MICROARC oxidation (MAO) . A method of oxygen microalloying on the surface of titanium alloy by micro-arc oxidation electrode is presented, which is suitable for manufacturing high-power elastic components of spacecraft:

1.It can increase the hardness and wear resistance of the structural mating surface.

2.Capable of providing a wide range of properties required by the part material to form a composite material with a predetermined set of properties.

3.Titanium alloys and structures made of them that can be strengthened by heat treatment without or without strengthening.

4.No complex and expensive process equipment is required, and in some cases no subsequent machining is required.

5.It can reduce the mass of the spacecraft’s lander.

Currently limited by technical qualifications and process strength, the use of oxygen microalloying in single and small-scale production is economically more appropriate.
