| Abstract: | The results of an increase of wear and corrosion resistance of the working surfaces of transfer press molds by means of the development and use of the microarc oxidation method are given. The protective coatings obtained enabled an increase their service life mainly within the most stressed area of the junction (closing area) and its sharp edges. Taking into account the processes occurring in the transfer press molds, the best properties of the coating and their operation modes are specified. The laboratory tests of coatings for bending, compression with shear, wear and thermal resistance, as well as tests on the structure of the transfer press mold in full-scale production proved their safe operation over 105 cycles without any damage. |
