The article shows that in comparison with interaction of steel surfaces the use of aluminum alloys with micro-arc oxide coatings on effective areas when manufacturing friction drives allows to increase a friction coefficient and their load capacity up to 3…8 times. And the inertance of its rotating components can be reduced substantionally and the dynamic qualities connected with inertance can be improved. That in combination with the increased wear resistance of micro-arc oxide coating and rather high damping properties of aluminum alloys determines the prospects of the use of aluminum alloys with these coatings in structures of precision friction drives of precise mechanical engineering, mechatronic systems of different purpose, including robotics.
