Финишные и отделочные методы обработки деталей машин

Abstract

In lucrare au fost analizate rezultatele experimentale si exploatationale ale sculelor aschietoare de strunjit si frezat dotate cu insretiuni din carburi metalice si oteluri rapide acoperite cu straturi rezistente la uzura. Se arata ca durabilitatea sculelor aschietoare depinde de structura multistrat, de componenta straturilor si de metoda de aplicare a straturilor. Sunt analizate in principal doua metode a aplicare a straturilor si anume Chemical Vapor Deposition si Phisical Vapor Deposition.

The paper analyzed the experimental and operational results of turning and milling cutting tools equipped with metal carbides and high-speed steels covered with wear-resistant layers. It is shown that the durability of cutting tools depends on the multilayer structure, the composition of the layers and the method of applying the layers. Two methods of layer application are mainly analyzed, namely Chemical Vapor Deposition and Physical Vapor Deposition.
