Resumo
The tribological problems, which have to be taken into consideration in micromachines, micromechanisms, Micro Electro Mechanical Systems (MEMS) devices and components such as silicon micromotors, toothed gears, gas turbines etc. are discussed. In such systems appear entirely different problems as compared with tribological problems in macroscale machines. It was proved that the values of friction parameters in the devices where the contact area is some millimeters square cannot be applied to the situation when the realistic contact area is only some micro- or nanometers square as well when the geometrical dimensions are changed.
