To improve the performance of micro-motors, internal combustion modelers increasingly use parts from non-ferrous metals. For example, the cylinder liner can be made of brass, and the piston is of aluminum alloy. To such a pair worked better, mirror shells coated with a layer of chromium.
On the Republican syut in Alma-ATA, chrome plated cylinder liners of engines with a working volume of 2.5 cm3 with a special suspension, which greatly facilitates the time-consuming process.
The suspension itself consists of an ebonite body with a groove in the lower part under the flange of the sleeve. Top in detail on epoxy glue is inserted into lead terminal is the anode. Around it are drilled 8 holes Ø 2 mm, which are used to drain from the internal cavities of the hydrogen generated in the chrome plating process. There is also a ebony cover: between it and the housing is brass ring is the cathode. Cover drawn by three M3 bolts.
