【 摘 要 】

Nonabrasive finishing of precision mating surfaces in locking devices with the use of a combined erosion-chemical process at the first stage of the processing and with the use of anodic dissolution by alternating low-voltage current at the final stage of a refinement operation till gapless joints obtaining is considered. It is shown that the application of electro-erosion, electrochemical and combined nonabrasive finishing in mating parts opens up a possibility to ensure stable impermeability in locking devices on a macro- and micro-level through the method of a substantiated purpose of technological modes. A procedure is created for the development of such modes, and on their basis technological processes for the obtaining of gapless mating surfaces meeting the performance requirements for locking devices are developed. For this purpose, qualitative devices resistant to hostile environment are manufactured that is urgent for the mechanical engineering including repetition work for the equipment of petrochemical industry, transport and household machinery.
