Abstract

Steel parts and structures are often used in an aggressive environment, which causes corrosion. Corrosion leads to deterioration of the mechanical properties of steel in two ways. First, it reduces the area of the carrying cross sections. Second, it increases surface defects, which are stress concentrators. Therefore, it is necessary to study the impact of corrosion on the mechanical properties of steel. The paper reviews the methods for causing corrosion of steel specimens for mechanical testing. The impact that the corrosion method and the degree of corrosion have on the mechanical properties of steel is also discussed.

Highlights

  • Mechanical properties of traditional construction materials have been studied closely as the structures behaviour depend on them

  • The aim of the present study is to review the methods that cause corrosion of steel specimens for mechanical testing

  • Nowadays the salt spray test is widely accepted as a method of testing paints and other anti-corrosion coatings [9, 11]. It is a well-known and proven fact that it has a number of drawbacks, which often bring in question the results both in coatings and in obtaining corroded specimens for mechanical testing:

Summary

Introduction

Mechanical properties of traditional construction materials have been studied closely as the structures behaviour depend on them. That can lead to an unexpected behaviour and even to an unexpected destruction of the structure The study of such an effects is done using specimens, which are first subjected to the corrosion impact, and to mechanical tests. The aim of the present study is to review the methods that cause corrosion of steel specimens for mechanical testing. It will analyse the impact of the corrosion method and the degree of corrosion on the mechanical properties
