Stressstrain state of vacuum plasma and electric-coating to enhance cutting tool

Abstract

The growing interest in machine building and other industries aimed at creating products with an optimum combination of the properties of the surface layer and the core material. Therefore, the rational design of coating discrete structure by analyzing the stress-strain state will increase the life of structures and tools, working in extreme load conditions, high temperatures and speeds, and allow evidence-based approach to their design and application. The solution to this problem in the calculation of the stress state song "base coating" with operational and technological factors was performed the following steps: solving the unsteady heat conduction to determine residual stresses resulting coating; determine the stresses on the power load and temperature; determining stress by superposition. The article describes and analyzes the results of the numerical calculations of the stress state of the basics of vacuum plasma coatings and coating EIL determined their optimal thickness and density. Built finite-element models with discrete cutting tool coatings, analyzed stress-strain state in the concentrated and distributed load considering residual stresses and temperature.
