Abstract

This diploma thesis deals with an experiment in which the influence of different patenting speeds on the resulting mechanical and fatigue properties of a patented steel wire was observed. total of 4 different patenting speeds were used in this thesis, namely 1, 2, 3, 4 metres per minute, followed by tensile, torsion, bending, fatigue testing, microhardness determination and interlamellar distance measurement were subsequently carried out. Drawn wires nowadays find application in a wide range of industries. They are most commonly seen in the automotive or aerospace industries, where they serve as reinforcements for tyres or springs for cars, for example. This paper takes a closer look at the description of wires that are used as a material for braiding high pressure hoses. These hoses must be braided for safety, durability and usability of the hoses at high pressures.
