This article examines the range of issues related to the construction of the subway in Ho Chi Minh City, Vietnam, using the example of the newly built Thu Thuem area as an example. The problem of construction lies in the difficult mining and geological conditions of Ho Chi Minh City. The geological structure has terrigenous-mineralogical associations, which makes the underground tunneling of the subway lines very difficult. Therefore it was decided to build the subway on trestles, but the calculation of foundations on terrigenous-mineralogical associations requires a detailed geological study.

The use of anti-friction materials in moving units reduces the likelihood of component wear, increases reliability, service life of parts and mechanisms as a whole. The paper considered the effectiveness of molybdenum coating in the design of oil and gas fittings, namely, an axisymmetric check valve and a control valve. Tests for strength, thickness, microhardness of the coating in the rack and pinion mechanism of oil and gas fittings were carried out.

Keywords: molybdenum, plain bearing, rack and pinion mechanism for oil and gas fittings, coating parameters, tests
