Improvement of mechanical characteristics of a cutting edge of the blade instrument by means of electromechanical processing

Abstract

It is shown, that in case of electro mechanical handling (EMH) of the blade instrument shaping of the cutting edge consisting of high dispersible martensite (a white stratum) is taking place, which is distinguished by heightened durability and endurance. Energy requirement of white stratum's forming in case of the restricted heat sink are established. The features of white stratum forma-tion by the width commensurable with the sizes of the hardened instrument are discussed.
