Investigation of strength of pressure couplings with various types of metal coatings

The role of pressure couplings in mechanical engineering and their advantages are shown. The conditional division of the coatings of one of the parts of the pressure coupling into groups is given. The dependence of metal coatings on the design and technological features of the coupling is noted. A contact model is given. Studies of the strength of pressure couplings with various types of metal coatings were performed. Conclusions have been drawn.
