ANSWERS TO THE CRITICISM CONTAINED IN THE PAPER OF V. B. NOSOV, V.I. PUSTOVALOV, AND S.A. YURASOV 'ON THE PROBLEM OF THE EXPEDIENCY OF A SECTION ON SURFACE ENGINEERING'

摘要

A constantly high quality of ready parts can be provided only in one case, i.e., if we manage to create conditions for the formation of a stable structural state, which is possible only in the case of an optimum combination of various operations in the complex process of production and hardening of parts. Therefore, efficient new hardening technologies can be provided only by improving the entire production process. We cannot hope for only the finishing operations, and solely for quenching, or for control of the ready products. The quality of the parts should be controlled during the entire manufacturing process. For example, for gears we should control the chemical composition of the steel, its initial hardenability and processibility, the precision of the geometry and weight, the microstructure of the forgings, the presence of work hardening, the quality of the microstructure of the surface layers after diffusion saturation, and the structure and properties of the parts after quenching and tempering.All the negative phenomena that hamper or prevent the production of quality parts should be determined from the standpoint of technological inheritance, and the entire production process should be organized from the standpoint of surface engineering in order to make maximum use of the positive effects of the technological inheritance and to eliminate the negative effects so that the prior operations should not complicate the subsequent ones.
